Backend-Focused Full-Stack Developer
I build production-ready systems with Django REST, Flask, PostgreSQL, React, and Next.js.
[SYSTEM_STATUS]:
Active๐ข [FOCUS]:Scalable Backend Architectures[MISSION]:Ship software that survives production
I do not build throwaway demos. I build applications like they are going to be used.
- Clean APIs that make frontend work easier
- Secure authentication and authorization flows
- Database structures that can grow with the app
- Production deployments that actually work outside localhost
- Debugging when real-world issues appear
A production-deployed e-commerce system built with Flask, PostgreSQL, Redis, and real backend workflows.
What makes it real:
- Email + Google OAuth authentication
- Cart, wishlist, checkout, and order management
- Stripe payment flow
- Admin dashboard
- Deployed on Render
A simulated internal hotel operations system built with Django REST Framework and React, designed for staff and admin workflows rather than customer-facing booking.
๐๏ธ System Architecture:
- Frontend: React + React Query
- API Layer: Django REST Framework
- Database: PostgreSQL
- Cache / Broker: Redis
- Background Jobs: Celery
- Deployment: Railway + Vercel
โจ Highlights & Production Wins:
- JWT authentication and role-based access with invite flows and protected APIs.
- Migrated from local SQLite thinking to production PostgreSQL behavior.
- Configured Redis for caching and task brokering; deployed a separate Celery worker service for async workflows.
- Solved CORS issues across Railway and Vercel.
- Integrated async email delivery using Resend.
- Debugged production logs and network issues instead of guessing.
๐ What I Learned:
- How frontend and backend deployments interact in production.
- Why environment variables matter more than localhost configs.
- How async task queues work with Celery and Redis.
- How production debugging depends on logs, retries, and service separation.
- How to design internal tools instead of only customer-facing apps.

Build clean. Ship real. Debug the hard parts. Improve until production feels boring.
