About

Professional summary

I am a Full Stack Developer and Software Engineer with over two years of experience designing, building, and deploying production web applications end to end.

I specialize in modern JavaScript and TypeScript development, with hands-on experience using React, Next.js, Node.js, Express.js, and REST APIs to create responsive and scalable applications.

I work with relational and NoSQL databases including PostgreSQL, MongoDB, Supabase, Neon, and Prisma. I design database schemas, build backend logic, and create reliable API integrations.

I have experience developing AI-powered products that combine OpenAI APIs, web retrieval, retrieval-augmented generation workflows, and automated PDF report generation.

I also build real-time and network-focused applications, including systems using WebSockets, ARP scanning, WinPcap, traffic control, and persistent leaderboards.

I focus on accessible user interfaces, input validation, predictable error handling, correct data flows, and dependable deployments using Docker, Vercel, Git, and CI/CD practices.
