SERVICES

My Services

I own products end-to-end - from architecture and database design to deployment - using React, React Native, and NestJS to turn ideas into scalable, production-ready applications.

01

Custom Web & Mobile Development

I build responsive web applications with React, Next.js, and TypeScript, and cross-platform mobile apps with React Native (Expo & Bare) - tailored for performance, scalability, and long-term maintainability.

02

Full-Stack API & Backend Development

I architect robust backend systems with NestJS, TypeORM/Prisma, and MySQL/PostgreSQL - including REST and GraphQL APIs, JWT auth, dynamic role-based access control, and DDD/CQRS-driven module design for complex business logic.

03

Frontend Optimization & Integration

I optimize frontend performance with code splitting, lazy loading, and efficient rendering, and integrate GraphQL/Relay data layers and third-party services like Stripe and PayPal for secure, production-grade payment flows.

04

Database Design & System Architecture

I design efficient database schemas and migrations, and build back-office tooling - bulk data import/ERP mapping, analytics dashboards, tiered business logic - to keep data integrity intact as products scale.

SKILLS

My Advantages

I use a solid mix of modern tools to build reliable web and mobile applications, working with React and React Native on the frontend and NestJS, TypeORM, and MySQL on the backend.
