About me
Thanks to working in a software development company, I was able to gain experience delivering web & mobile projects across multiple industries using modern JavaScript frameworks as a full-stack engineer.
I'm a full-stack engineer with 8+ years of hands-on experience building high-performance web and mobile applications from end to end. I specialize in modern JavaScript/TypeScript ecosystems and cloud infrastructure to deliver scalable, maintainable solutions that drive real business results.
Core expertise:
Frontend: React, Next.js (SSR/SSG/App Router), React Native (iOS + Android cross-platform apps), Angular 16+
Backend: Node.js (Express/NestJS), Python (FastAPI, Django, Flask)
Cloud & DevOps: AWS (EC2, S3, Lambda, RDS, Amplify, CloudFront, API Gateway, Cognito), CI/CD pipelines, Docker basics
Databases: PostgreSQL, MongoDB, MySQL, DynamoDB
Other: REST/GraphQL APIs, authentication (JWT, OAuth), performance optimization, responsive design, testing (Jest, Cypress)
I’ve delivered projects for startups and mid-size companies in e-commerce, SaaS tools, fintech, health-tech, and education — ranging from MVPs launched in weeks to complex platforms handling thousands of daily users.
Clients value my:
Clean, modular code & best practices
Clear communication & realistic timelines
Focus on performance, security, and scalability
Post-launch support & quick iterations
Available for long-term partnerships, fixed-price projects, or hourly work. Let's discuss your idea — whether it's a new SaaS product, mobile app, complex dashboard, or API integration — and turn it into a production-ready solution.
Looking forward to working together!
