You need software that works in production, not just in a demo. That's what I build. My background is enterprise software, I spent a year at WSO2 shipping Java backend features across two product releases used by enterprise clients worldwide. That taught me what it takes to write code that doesn't break when real users depend on it: clean APIs, proper testing, and deployments that actually hold up. What I deliver: • Backend APIs (Java, Python/FastAPI, Node.js) with Swagger documentation • React frontends that connect cleanly to your backend • PostgreSQL and MongoDB schema design through optimization • Docker, CI/CD pipelines, and cloud deployments (AWS, DigitalOcean) • OAuth 2.0 and API security when your project needs it How I work: Clear communication, no disappearing acts. You get working code, not excuses. I scope honestly, deliver on time, and flag problems early instead of hiding them. Whether you're building from scratch or need someone to stabilize what's already running, I can help. Let's talk about your project.
