Back End Developer

Freelance · Jan 2024 – Present

Not yet confirmed
  • API development: designed and built REST APIs in Flask for a production rental-platform startup, documented with Swagger/OpenAPI for frontend and third-party consumption.
  • Cloud deployment: deployed and ran backend services on AWS EC2 with S3 for storage; authored the backend architecture diagram used to plan the system end-to-end.
  • Performance decision: proposed and implemented Cloudinary for image handling, using its multi-resolution delivery to shrink product photos from 3–4MB to 15–100KB variants for faster load times; scoped a future migration to AWS as usage scales past the free tier.

Developer

Jagruk Durbe · Jan 2025 – Jan 2026

Not yet confirmed
  • Full-stack platform: Flutter frontend, FastAPI backend with 86 endpoints across 16 routers, and a SQLAlchemy ORM with Alembic-managed migrations — architected and built end-to-end as sole developer.
  • Security: JWT auth with OTP verification, role-based access control (user / admin / super_admin), and a purpose-bound OTP enum that prevents cross-flow replay attacks.
  • Hardened image pipeline: MIME check → size limit → NudeNet NSFW screen → signed Cloudinary upload; per-endpoint rate limiting, bcrypt hashing, env-based secrets.
  • Performance: display-time Cloudinary URL transforms cutting image payload 60–80% via on-the-fly auto-quality and auto-format — critical for rural 4G performance.
  • Data integrity: soft-delete with audit trails across all data models, and a 6-month rating cooldown enforced at the query layer.
