About this gig

Are you looking for a reliable full-stack developer to build or improve your web application?

I'm a Software Engineer with 3+ years of experience building production-grade web apps using Django, Django REST Framework, and React.js. I've worked across manufacturing, sales, and financial-service systems, delivering scalable backends and clean, responsive frontends.

What I can help you with:

Full-stack web app development (Django REST API + React UI)

Fixing bugs and improving existing Django/React codebases

Backend performance optimization (resolved N+1 queries, reduced API response time from seconds to milliseconds)

Third-party API integrations (Stripe, VNPT e-Invoice, KiotViet, SMS/push notifications)

Database design (PostgreSQL, MySQL) and REST API architecture

Real-time features using Django Channels

Why work with me:

  • Proven track record on production systems, not just tutorials
  • Strong problem-solving background (ICPC national/regional rounds)
  • Clear communication and clean, maintainable code
  • Fast turnaround without compromising quality

Whether you need a new feature built, a bug fixed, or a full application developed from scratch, I'll deliver working, well-structured code you can
