For this 30-35 day engagement, I can personally take ownership of the Java 17/Spring Boot backend and React Native architecture while working directly with your Backend Engineer and 4 Frontend Interns. I also understand this is an individual contributor role with active Slack participation, PR reviews, architectural decisions, and production accountability throughout the contract. I’d work within your existing Java 17, Spring Boot, MySQL, microservices, JWT, AWS EC2/IAM, Jenkins, SonarQube, JUnit/Mockito, and React Native stack rather than introduce unnecessary technology changes. My two priorities would be scalability and maintainability: query/index tuning, transaction boundaries, service contracts, and performance profiling on the backend, plus clear React Native module/state conventions using Redux or Zustand on mobile. I’d also establish PR standards, testing expectations, folder/service conventions, and mentor the team through difficult features such as real-time matching, KYC, sensitive workflows, third-party integrations, and AI wrappers. Core architecture, debugging, security, and production logic would be reviewed and owned directly, not delegated to AI-generated code. Relevant project: FileChannels, where I worked across real-time communication, mobile workflows, messaging, file handling, integrations, and production-facing architecture. I can commit for the full 30-35 days.

@Abror86

Hi-Abror Here From Uzbekistan. "Deliver Java 17 And React Native Development" - I can deliver Java 17 services and React Native features with clean architecture, refactoring, testing, performance improvements, and integration. I can develop Java 17 backend services and React Native features, refactor existing code, improve performance, and maintain clean architecture across both platforms efficiently reliably. I will implement features, review pull requests, test integrations, resolve defects, document decisions, mentor developers, and deliver production-ready updates within your required thirty-five-day timeframe successfully. Can you share the current architecture and highest-priority features planned for this 30-35 day engagement? Looking forward to working with you.

@mikes126

I would first review the existing architecture, service dependencies, API contracts, database access, React Native structure, and current performance bottlenecks. Then I would implement new features end-to-end with clear separation of concerns, validation, error handling, and maintainable code. A key challenge in similar full-stack systems is keeping backend and mobile changes synchronized without introducing regressions. I address this through well-defined API contracts, backward-compatible changes, reusable components, automated testing, logging, and structured refactoring. 3.1 For performance issues, I would profile Java services and database queries, optimize expensive operations, improve caching where appropriate, and reduce unnecessary React Native renders/network calls. 3.2 I would also review pull requests, establish coding standards, mentor junior/mid-level developers, and contribute to the long-term technical roadmap. For your project, I can take ownership from Java 17 service development through React Native implementation rather than treating backend and mobile work as separate tasks.
