Hi, I'm Tekeshwar 👋

Senior software engineer. I build backend systems, AI pipelines and agent tooling, and ship mobile apps at scale.

🤖 AI engineering

Small, focused tools for the parts of LLM apps that break in production.

  • deprecation-mcp: an MCP server that tells an agent whether a vendor API or SDK is active, deprecated or sunset, so upgrade work checks before it breaks instead of after.
  • rag-latency-profiler: runs one full RAG cycle, measures the metrics that matter for LLM apps, and shows with a failing case why 200 OK is not a health signal.
  • Agent Eval: LLM-as-judge evaluation, so you can tell whether a prompt or model change made your agent better or worse.
  • research-agent: a Plan → Research → Write → Review multi-agent pipeline with Zod-validated structured outputs.
  • groundwork: an Agent Skill for Claude Code, Codex and Cursor. Plan a project once, then pick it up where you left off.

🛠 Building

  • pglens · pglens.org: a no-code PostgreSQL workstation. View, explore, visualise, edit and query your database from a local web UI. One-line install.

💼 Work

  • xFarm Technologies: Flutter apps for a farm platform serving 600k+ farms in 14 countries.
  • Breakthrough: multi-tenant Stripe billing on AWS ECS, AI media indexing with Gemini-reranked vector search, a Vertex AI smart-search pipeline, and a Next.js paywall serving 60+ brands from one codebase.
  • PixelApps / Pingolearn: Clean Architecture Flutter, and an AI language-learning app with 700k+ users.
