  • AI Software Engineer at Advice Bytes
    May 2025 - Sep 2025 · 5 mos

    Worked on Sector8.ai, a secure middleware observability platform for GenAI applications. Designed and implemented Supabase-backed APIs to ingest and evaluate LLM prompt-response telemetry, using project-scoped API keys and JWT-based auth. • Built secure backend APIs to collect AI prompt and response data, and set up checks to control who can access it using API keys and login tokens. • Added tracing (using OpenTelemetry) to track how AI and database systems are working. This helped in finding bugs and understanding costs. I helped create a system that flags toxic, biased, or incorrect AI responses, making the product more reliable. • Contributed to both backend and frontend parts of the project and helped launch it online using Vercel.
