Slow backend? Unclear architecture? Need a complete web application built and deployed — without managing three different contractors? I build production-ready Java + Spring Boot backends paired with clean React frontends, deployed on AWS or GCP. Six completed Upwork contracts, three cloud certifications (AWS Solutions Architect, Oracle Java SE, GCP Associate), and a consistent track record of shipping systems that work on day one and stay maintainable at month twelve. What I deliver end-to-end: — Spring Boot REST APIs with OpenAPI documentation and proper error handling — Secure authentication: JWT, OAuth 2.0, role-based access control — PostgreSQL / MySQL database design with clean data modeling — React dashboards, admin panels, and workflow UIs wired directly to your APIs — Docker containers deployed to AWS (EC2, ECS, RDS) or GCP — CI/CD pipelines so your team ships without manual steps What makes this engagement different: I write documentation. I design APIs before I build them. I flag problems before they become your emergency. And I don't hand off code — I hand off a system you can actually operate. Best fit for: - SaaS startups that need a reliable backend with a functional frontend in 2–6 weeks - Teams replacing spreadsheets or manual workflows with internal tools and admin panels - Technical founders who want one accountable engineer, not a fragmented team My specialty is projects where the backend has to be correct — auth flows, data integrity, business logic, third-party integrations. The frontend needs to be functional and maintainable. If you need pixel-perfect animations, I'll refer you to the right person and stay focused on what I'm actually great at. Three certifications. Six contracts. Zero missed deadlines. 📩 Send a brief on your project — I respond within 4 hours (9 AM–9 PM IST). I offer a free 20-minute scoping call for projects that are a clear fit.
