Hi, I'm Dhayanidhi

Backend Software Engineer

I build and deploy production-grade backend systems. From API design and database modeling to Linux deployment, cloud storage, and real-world integrations — I own features end-to-end.

About Me

Backend Engineer with Real Production Experience

I’m a backend-focused software engineer working primarily with Python, FastAPI, PostgreSQL, and SQLAlchemy. I don’t just write APIs — I design systems that run in production.

Since joining my current company, I’ve worked on multiple live products including booking systems, CRM integrations, call-recording platforms, AI-assisted workflows, and e-commerce backends.

My responsibilities regularly include database design, writing and optimizing SQL queries, integrating third-party services, deploying applications on Linux servers, configuring Nginx, Cloudflare, SSL, cron jobs, and managing AWS S3 storage.

I’m comfortable taking a feature from requirement → implementation → deployment → production debugging — without hand-holding.
