Internal Automation Tool (LLM API + File-Based Workflow)
Aravinth built a file-driven automation system with Claude API integration, Google Drive routing, and a verification loop - all in under 2 days. He delivered exactly what we discussed, on time, and the system worked out of the box.
What impressed me most:
Speed: He moved fast. No delays. He quoted 1-2 days and delivered in 1-2 days.
Clean handoff: He walked me through the system via Zoom and made sure I understood how everything worked before wrapping up.
I immediately hired him for a second contract to extend the system.
Highly recommend.

Internal Automation Tool (LLM API + File-Based Workflow)
Exceptional developer. Highly skilled and professional
Aravinth delivered a complex system automation tool involving Google Drive integration, Claude API routing, verification loops, admin and client UIs, and deployment across multiple platforms. The result was exactly what I needed.
What stood out:
Technical excellence: He built a full-stack system from scratch with a Python backend, Next.js frontends, Google OAuth, multi-model Claude API routing (Opus/Sonnet/Haiku), and deployment via Vercel, Render, and GitHub. Everything works.
Clear communication: He asked smart clarifying questions, confirmed understanding before building, and kept me informed throughout. No guessing, no surprises.
Efficiency: He works fast and delivers on time. The entire system was built, tested, and deployed in days.
Professionalism: He walked me through the architecture and setup via multiple Zoom calls so I could manage things independently going forward. He knows his craft and explains it clearly.
Aravinth is the real deal. You aren't paying for someone to "figure it out". He's skilled, reliable, and easy to work with. I could not be more pleased with this working relationship. I'll be hiring him again.
