I build high-performance, scalable software using Next.js, React, Node.js, and modern tech stacks — new products, existing applications, technical improvements and custom development. If it needs to be built, improved, fixed or integrated, you're in the right place.
From new builds to fixing what already exists — and if your requirement isn't listed, contact me anyway and we'll figure it out.
New products, applications and platforms — built end to end.
Complete production-ready applications — frontend, backend, database, auth, APIs and deployment.
Responsive UI, design implementation, component systems and dashboard development with React & Next.js.
Node.js/Express REST APIs, MongoDB, authentication, role-based systems and integrations.
Cross-platform mobile apps with React Native, connected to real backend APIs.
Business websites, portfolios, SaaS apps, admin panels, dashboards and custom platforms.
For founders and early ideas: Idea → Planning → Architecture → Development → MVP → Deployment.
Installable, offline-capable, app-like web experiences that run everywhere.
Figma or any design reference → responsive, production React/Next.js implementation.
Already have a codebase? I extend, fix, optimize and ship it.
You don't need to start from scratch — I work on existing codebases: features, fixes, refactors, deployments.
Bugs, responsive issues, API problems, performance bottlenecks — diagnosed and fixed.
Frontend/backend deployment, database setup, environment config and third-party integrations.
Developer support, consultation and everything in between.
Debugging guidance, code review, architecture and deployment guidance for developers and teams.
Every project is different. If your requirement isn't listed here, share what you're trying to build, improve, integrate, or solve. I'll review the requirement and see how I can help.
