Hi, React, NestJS, PostgreSQL, and AWS are my daily stack — I've built and maintained SaaS platforms with similar architecture (scalable backends, REST APIs, CI/CD pipelines, code reviews included). I write clean, well-documented code and work comfortably in remote async teams — no hand-holding needed on process or tooling. 10 years full-stack | 5.0 rating | 100% on-budget delivery. Hourly rate: ₹750 — available to start this week. Happy to do a short technical call before you decide. Ronak

I’m a full-stack developer with strong experience in React and NestJS, and I can contribute effectively to building and scaling your ticketing and event management platform. I’ve worked on applications that require clean architecture, high performance, and reliable API integrations, using PostgreSQL for structured, scalable data handling. My approach focuses on writing maintainable code, building efficient REST APIs, and ensuring the frontend remains fast and responsive across devices. I’m comfortable working with AWS for deployment and infrastructure, including CI/CD workflows, and I actively participate in code reviews and technical discussions to keep projects moving forward. I also have experience debugging complex issues across frontend and backend layers, which helps maintain stability as features evolve. I can collaborate closely with your team, deliver production-ready features, and help optimize performance while keeping the codebase clean and extensible.

The core challenge here isn't just React + Nest. js, it's architecting scalable event/ticketing features that handle real-time updates, amplu state, and AWS Lambda integrations without performance bottlenecks. I've built 28 React/Next. js projects and 10 Node. backend systems in the last 2 years, including real-time dashboards, API integrations, and serverless architectures. My stack includes PostgreSQL improvement, RESTful API design. AWS deployments. Recent relevant work: https://www.freelancer.com/portfolio-items/11324131 https://www.freelancer.com/portfolio-items/11324098 I work extremely fast with modern tooling and can start immediately. Since I'm building my Freelancer profile, I'm offering a competitive rate to earn strong reviews while delivering production-ready code. Ready to contribute to your engineering team.

I have strong experience building scalable React and Node.js applications with clean architecture, REST APIs, and PostgreSQL. While my experience is slightly below the requirement, I am highly skilled in working on production systems, optimizing performance, and quickly adapting to complex codebases.
