Project Description Overview I have a Windows desktop application that is approximately 90% built and I need an experienced engineer to take it across the finish line: close out the remaining feature work, build a proper automated test suite, set up a production CI/CD pipeline, integrate code signing, and ship the first signed public release. This is a fixed-scope, fixed-deliverable project with a defined end date. It is not an open-ended retainer. If the engagement goes well there may be ongoing maintenance work afterwards, but that would be negotiated separately. The product is a productivity tool for business users. Further detail on the product itself will be shared after an NDA is signed — please don't ask me to describe the product concept in the public chat. Current State Core application is built and functional in development Frontend, backend, database schema and native audio layer are all implemented What's missing is the last mile: edge-case handling, hardening, tests, packaging, release infrastructure and production deployment Tech Stack Desktop: Electron, React, TypeScript Native module: Rust sidecar (Windows audio APIs via windows-rs), IPC to Electron main process Backend: Node.js + TypeScript (NestJS) Database: PostgreSQL with pgvector, on AWS RDS Infra: AWS (us-east-1) Auth: WorkOS Real-time: Authenticated WebSockets Target platform: Windows 10/11 only (no macOS, no Linux) Scope of Work 1. Finish remaining feature work (~10%) Close out a defined punch list of outstanding items (list provided post-NDA) Error handling, edge cases, loading and empty states Reconnection/recovery logic on the WebSocket layer 2. Automated test suite Unit tests for backend services and business logic Integration tests covering the API and database layer End-to-end tests for critical desktop user flows Basic test coverage for the Rust sidecar and its IPC boundary Target: sensible, meaningful coverage of critical paths — not a coverage-percentage box-tick 3. Build & release pipeline electron-builder + NSIS installer configuration electron-updater auto-update with stable and beta channels and delta updates Code signing for both the Electron app and the Rust sidecar binary (EV certificate will be procured and provided by me — you configure the signing integration) GitHub Actions CI/CD: build, test, sign, publish signed artifacts to the update feed Reproducible builds, versioning and release tagging 4. Observability Sentry integration on the Electron process and the Rust sidecar (including native minidumps) Sensible error grouping and release tracking 5. Production deployment Deploy backend to AWS Environment/secrets management Basic runbook documentation for deploys and rollbacks Deliverables Punch-list items completed and merged Passing test suite running in CI on every PR Working GitHub Actions pipeline producing signed installer artifacts Auto-update verified working across two sequential versions on a clean Windows machine Backend live in production on AWS Sentry receiving errors from both processes Short written handover document: architecture notes, deploy runbook, rollback procedure Milestones # Milestone Payment 1 Punch list complete, all features working in dev 25% 2 Test suite complete and green in CI 25% 3 Signed build pipeline + auto-update verified end-to-end 30% 4 Production deployment, observability live, handover doc delivered 20% Required Experience Essential: You have shipped and signed a production Windows Electron app — not just built one locally Hands-on experience with electron-builder and electron-updater (channels, delta updates) GitHub Actions CI/CD for desktop application release pipelines Strong TypeScript across both Node backend and React frontend Working knowledge of Rust — enough to test, debug and maintain an existing sidecar Comfortable with AWS deployment and PostgreSQL Nice to have: Windows audio API experience (WASAPI) NestJS pgvector Native crash reporting / minidump handling Terms NDA required before any product detail or repository access is shared Full IP assignment — all work product assigns to my company. A written contractor agreement will be signed before work starts. You must confirm you have the right to take on this work — i.e. no employer agreement or existing obligation that would conflict with assigning IP on this project Work performed on your own equipment and accounts Credentials will be scoped and revocable; you will not receive production root access To Apply Generic or copy-paste bids will be ignored. Please answer the following in your proposal: Link me to a Windows Electron app you have shipped and signed. What signing method did you use — hardware token, cloud HSM, or a signing service? EV code signing certificates are generally bound to hardware tokens or HSMs. How would you integrate that into a GitHub Actions pipeline? Tell me what you'd actually use. Have you worked with a Rust binary as a sidecar to an Electron main process? What IPC mechanism did you use, and how did you handle sidecar crashes? What is your testing approach for an Electron app? Which frameworks would you use for E2E, and how do you handle the main-process/renderer split? Roughly how many hours do you estimate for this scope, and what is your availability per week? State your fixed price for the full scope and your hourly rate separately.

Hi — Elias here from Miami. I see you’re looking to finalize a Windows Electron app with React and TypeScript. Completing this project involves more than just finishing the remaining features. The goal is to ensure a stable, well-tested application capable of reliable performance. What usually matters most here is establishing a solid CI/CD pipeline that integrates seamlessly with your current setup. A common issue in projects like this is ensuring that the testing suite adequately covers all functionalities, which is critical for maintaining quality as the app evolves. The tricky part is usually managing dependencies and ensuring compatibility across various Windows environments. My approach would focus on maintainability and scalability. I’d implement systematic testing and automate deployment processes to streamline updates. Having worked on similar desktop applications, I understand the importance of robust documentation. A few questions to better understand the scope: Q1 – What specific features remain to be implemented, and are there any critical deadlines? Q2 – How is your current testing framework structured, and what coverage do you have? Q3 – Are there any particular integrations or third-party services that need to be included? Happy to go through the details and suggest the best approach. Looking forward to hearing from you.

Taking a 90%-built Electron/React/TypeScript app across the last mile — hardening, tests, CI/CD and a signed release — is exactly the kind of work I enjoy, and your stack (Electron + NestJS + a Rust/windows-rs audio sidecar over IPC, PostgreSQL/pgvector on RDS, WorkOS auth, authenticated WebSockets) is squarely in my wheelhouse. I'd close out the punch-list features first, then build a layered test suite — Jest/Vitest units, IPC and NestJS integration tests, and Playwright end-to-end for the Electron UI, including the Rust sidecar boundary. For release I'll set up GitHub Actions to build, test and package with electron-builder, integrate Windows Authenticode code signing, and ship the first signed Win10/11 installer with auto-update, plus a smoke-tested production deploy. Happy to sign the NDA and start right away.

Hello, I will finish your Electron + React/TypeScript app: close the punch list, wire up the Rust sidecar IPC recovery, build the test suite, configure electron-builder with NSIS and delta updates, and deliver a signed release through GitHub Actions. On a similar Windows Electron project, integrating EV signing via cloud HSM (DigiCert KeyLocker) into GitHub Actions kept the pipeline fully automated with no hardware token bottleneck. Questions: 1) For the Rust sidecar IPC, are you using stdin/stdout JSON, named pipes, or something else currently? 2) Is the WebSocket reconnection logic partially started, or does it need to be built from zero? Share repo access after NDA and I will deliver a detailed punch list review within 48 hours. Looking forward to your response. Best regards, Kamran

Hi, Thank you for considering my bid on your project. I am confident that I can deliver a high-quality solution within the defined scope. Here’s an overview of what I will do: 1. Finish Remaining Feature Work: I'll address any outstanding items, focusing on edge-case handling, error recovery logic, and ensuring robust loading and empty states. 2. Automated Test Suite: I’ll develop comprehensive unit tests for backend services, integration tests for API/database interactions, and end-to-end tests covering key desktop flows. 3. Build & Release Pipeline: I’ll configure electron-builder and NSIS installers, set up auto-updates with delta updates, and integrate code signing using an EV certificate provided by you. GitHub Actions will be used to build, test, sign, and deploy signed artifacts. 4. Observability: Sentry will be integrated for error tracking on both the Electron process and Rust sidecar. Error grouping and release tracking will ensure efficient debugging. 5. Production Deployment: I’ll handle backend deployment to AWS with proper environment/secrets management, provide a basic runbook for deploys and rollbacks, and ensure auto-update functionality. I have extensive experience shipping and signing production Windows Electron apps using EV certificates via cloud HSM services like Venafi. For the GitHub Actions pipeline, I would use the `sign` action by Snyk to handle code signing seamlessly. In my previous work with Rust sidecars in an Electron main process, I used IPC through channels for communication, ensuring robust handling of crashes and restarts. For testing approaches, I utilize Jest for unit tests, Supertest for integration tests, and Cypress for E2E tests. I also manage the main-process/renderer split effectively to ensure comprehensive test coverage. Estimating roughly 100 hours in total, with a mix of full-time effort over four weeks. My fixed price is $7,500, and my hourly rate is $80. Please review the details above and visit my portfolio at https://www.freelancer.com/u/reedsystems for additional references. I look forward to working together! Best regards, Reed

Hello, I work with Electron, React, TypeScript, Node.js, and PostgreSQL on release-ready desktop and web systems. For this Windows app, I can handle the remaining punch list, harden the WebSocket recovery flow, and align the Software Architecture with the signed release process. I would add unit, integration, and E2E tests around the backend, database, Electron main process, renderer, Rust sidecar IPC, and crash recovery. For EV signing in GitHub Actions, I would use a cloud HSM or signing service, then package with electron-builder, verify electron-updater beta and stable channels, deploy AWS, connect Sentry, and deliver the runbook.

Hi, I understand you need to finish an Electron/React app with Rust sidecar, set up a full test suite and CI/CD pipeline, and ship a signed Windows release. I shipped a similar Electron productivity tool last year with electron-builder, electron-updater, and EV code signing via cloud HSM in GitHub Actions—had to handle sidecar crashes and native minidumps in Sentry, which we can replicate here. I’d approach this using NestJS backend with deterministic builds in CI, Rust sidecar IPC with tokio channels for crash recovery, and Jest/Cypress for layered testing (unit, integration, E2E). The biggest improvement will come from reproducible pipelines isolating signing and updates before merge. I’ll restrict sensitive credentials to encrypted secrets and provide rollback steps in the runbook to keep the system maintainable. The goal is a stable release pipeline that lets you iterate without worrying about build or deployment issues. Happy to share the signed app link and dive into the details. I can start right now. Thanks, Denis.

Your Rust sidecar will fail silently in production if you don't configure minidump handling and Sentry's native crash reporting before the signed release ships. Most Electron devs skip this and only discover it when users report phantom crashes with zero logs. Quick questions - are you using an EV certificate on a hardware token or cloud HSM for the signing pipeline? And what's your rollback strategy if a signed update introduces a regression that breaks the auto-updater itself? Here is the architectural approach: - ELECTRON-BUILDER + CODE SIGNING: Configure dual signing for both the Electron app and Rust binary using your EV cert, set up GitHub Actions secrets for the signing token, and implement delta updates with stable/beta channels so users get sub-10MB patches instead of full reinstalls. - RUST SIDECAR TESTING: Build integration tests that validate the IPC boundary between Electron main process and the Rust audio layer, mock Windows audio APIs for CI environments where WASAPI isn't available, and wire Sentry native crash reporting so minidumps upload even when the sidecar segfaults. - CI/CD + AUTO-UPDATE VERIFICATION: Create a GitHub Actions pipeline that runs your test suite on PR, builds signed artifacts on merge to main, publishes to your update feed, and includes an automated E2E test that spins up a VM, installs version N, triggers an update to N+1, and verifies the app relaunches without manual intervention. I've shipped 4 production Electron apps with auto-update and code signing, including one that handles real-time audio processing on Windows. Let's schedule a 20-minute call to walk through your punch list and confirm the signing cert setup before we lock the timeline.
