I need a full-featured captive portal that lets guests connect to my WiFi, land on a responsive plan-selection page, and pay securely through Mercado Pago. The system must: • Offer time-based plans (with an additional free-trial option) and show them in a fully branded, custom-designed interface that matches my visual guidelines. • Process payments via Mercado Pago Checkout and listen for status updates through Webhooks. Once a payment is approved, the user’s MAC/IP should be automatically authorized on the gateway or controller for the purchased duration; when the time is up, access must be revoked without manual intervention. • Expose an internal REST API to authorize or de-authorize devices programmatically, so I can later integrate other services if needed. ...

We are a small food retail chain (ready-made meals, no tables, no waiters, no kitchen interaction) and we want to develop a very simple, web-based POS software customized for our needs. This is NOT a restaurant system with tables, waiters, KDS, or complex operations. It is a single cash register per store, with a fixed menu and very basic day-to-day functions. We are open to using an existing open-source POS as the base (e.g., OSPOS, WallacePOS), or any other modern framework you recommend — as long as the code is clean, maintainable, and easy to extend. This project is Phase 1 (MVP). Functionality must stay minimal and stable. ⸻ Core Requirements (MVP) 1.

I need a DevOps-savvy cloud engineer to stand up a fresh AWS environment that cleanly hosts a Node.js (Fastify/Express) API, a PostgreSQL RDS instance, and an S3 bucket dedicated to test artifacts and screenshots. The emphasis is on security best-practice, tidy networking, and a foundation I can grow over time. Here’s what matters: • The stack should sit inside its own VPC with public and private subnets, security groups, and routing configured for tight traffic control. • IAM must be role-based and least-privilege; use managed policies wherever practical. • I prefer manual scaling for now, so size the compute layer with right-sized instances and leave headroom for future Auto Scaling Groups once traffic justifies it. • Please wire everything into CloudWa...

I need our existing Python / Django website moved from its current host to a brand-new dedicated server running Debian Linux. The codebase and database are stable; the task is to replicate the full stack on the new machine, switch traffic over, and keep downtime to an absolute minimum. Here is what we expect delivered: • Provision the Debian server with all required packages (Python, virtualenv, pip, Gunicorn or uWSGI, Nginx or Apache, PostgreSQL/MySQL as used in the current setup). • Copy the project files, environment variables, media/static assets, and migrate the database. • Re-create any cron jobs, Celery workers, or background services the project relies on. • Point the domain, issue/renew SSL certificates, and verify HTTPS works. • Run functional ...

Our security-attendance platform is already live on a solid Python Django back-end with a fully tested REST API. What I now need, above everything else, is a modern ReactJS single-page front-end to replace the current server-rendered HTML. Once the web experience is refreshed, the same codebase should power companion iOS and Android apps through React Native, and the data layer must move from SQLite to PostgreSQL with zero downtime. Scope of work • Build a ReactJS SPA that consumes the existing API. Core pages to re-implement and polish are the Dashboard, User Profile, Project Management, Attendance + GPS, Companies, Invoices, and the dedicated Guard/Supervisor UI. • Fine-tune Attendance + GPS tracking; at the moment location capture sometimes drifts—behaviour must be ...

I am looking to bring a full end-to-end remote street-lighting solution from concept to live deployment. The luminaires already on site use DALI-2/D4i drivers with Zhaga sockets, so the hardware piece centres on Zhaga-mounted LoRaWAN nodes that can switch, dim and read diagnostics from each fitting. Those nodes must talk to robust gateways and the gateways, in turn, push data to the cloud over 4G/LTE. My top priority is granular control and monitoring at scale: every lamp must report power, driver health and runtime events, and accept command schedules or real-time overrides. To keep that data useful, the backend has to focus on reliable storage and processing pipelines—think PostgreSQL/Timescale, MQTT or LwM2M brokers, and clear REST or GraphQL APIs. Once the data lands, I need...

My Ubuntu VPS is brand-new, FastPanel is already in place, and the domain points to the server, but the site is still empty. I now want the GitHub project running there in production. The application expects Ruby 3.0.x, so you’ll begin by installing that exact version together with the right Bundler, Node.js and Yarn. PostgreSQL also has to be set up; please generate strong random credentials, plug them into , and send the login details to me privately. Once the dependencies are in, configure all environment variables, run migrations, pre-compile assets, and launch the app with either Puma or Passenger—whichever plays nicest with FastPanel. Finish by wiring the service through Nginx inside FastPanel so the site loads over my domain. I would like a short, clear note (in Russ...

Our newly launched IT firm is building a pool of reliable, senior-level freelancers who can jump straight into client work and keep quality high from day one. Every assignment you touch will involve real production code, so deep, hands-on expertise in Python, JavaScript, and Java is non-negotiable. Most of the work revolves around full-stack web development, mobile apps, and data analysis pipelines. Because many of our clients rely on us for end-to-end delivery, I’ll also expect you to steer project management—setting realistic milestones, coordinating with designers or QA, and reporting progress directly to me and, when required, to the client. If GIT, CI/CD, agile sprints, and clear documentation are second nature, you’ll fit right in. Typical engagement flow &bul...

I’m preparing our application for a major configuration overhaul and I need a rock-solid stored procedure that focuses exclusively on data validation. The procedure will run against our configuration tables before each deployment and must confirm that every record is correct before it reaches production. Scope of validation • Format & structure – verify each field follows the expected data type, length, and pattern rules. • Range & constraints – reject any values that fall outside permitted boundaries or violate business rules. • Dependencies between fields – catch cross-field issues (e.g., a flag set to “enabled” must have its companion value populated). What I’ll supply • Current table schema and sample confi...

I need my existing Odoo installation copied to a new server so that everything—core files, custom modules, configuration, and user data—works exactly as it does today. The target machine is already provisioned; what’s missing is the full Odoo stack mirrored, tested, and switched over with minimal downtime. Experience with Odoo deployment, PostgreSQL backups/restores, and Linux server administration is essential. If you can schedule the cut-over during a low-traffic window, even better. Thanks!

I’m building a new freelancing platform and the first milestone I want to tackle is the user-facing profile and portfolio area. What I need is a self-contained module that lets every freelancer create a polished profile, tag their skills, and collect endorsements from past clients or collaborators. Core requirements • Skill tags must be searchable, stored efficiently, and editable by the user. • Endorsements should function much like LinkedIn’s: a quick one-click action backed by a short comment, with safeguards against spam or duplicate entries. • A simple portfolio gallery where each item can reference external links or hosted media. • Clean, modern UI components ready to drop into a React or Vue front-end and a well-documented REST or GraphQL API f...

I’m ready to bring a high-performing recent Computer Science graduate onto my team for a full-time, fully remote role building and integrating analytics models. Your focus will be customer data, and your first challenge is to produce predictive analytics that help us anticipate behaviour and drive smarter product decisions. Day to day you’ll be coding in Python, shaping data pipelines with tools such as Pandas, SQL, or Snowflake, and exposing your work through light-weight REST or GraphQL APIs so it slots cleanly into our existing SaaS platform. I value strong academic results over workplace experience, so show me a standout GPA, clear reasoning, and solid knowledge of ML fundamentals. Deliverables for the initial month • A containerised predictive model trained on...

I have a handful of small web ideas that I want turned into clean, well-structured micro-applications written in Python with FastAPI. Each project is intentionally simple—think CRUD-style APIs, a couple of endpoints, and lightweight persistence—yet I still expect production-ready code: type-hints, Pydantic models, async handlers where it makes sense, and concise docstrings. Here’s how I see the workflow: • You receive a short functional brief for each micro-app (for example: “store and retrieve user notes” or “serve a filtered list of products”). • You implement the FastAPI service, wire up a minimal data layer (in-memory, SQLite, or Postgres—your call as long as it’s documented), add basic unit tests, and share a or so ...

I already hold an active SmartAPI key from Angel Broking and now need a developer to wire it into my analytics stack. The goal is simple: stream real-time stock prices, trading volume, and market indices into a format I can query or visualize at will. What I expect from you is a lightweight service—Python preferred because the rest of my tooling is in pandas and Plotly, but Node.js is fine if that speeds you up—that authenticates, subscribes to the relevant WebSocket channels, and keeps the connection alive with solid reconnect logic so no ticks are missed. Push the incoming data either to a small REST endpoint or directly into a Postgres table; choose whichever you can deliver most reliably. Deliverables • A runnable script or micro-service that continuously fetches t...
