Hi, I’m Pandurang.

Software craftsman with 14+ years of experience building scalable backend systems, and 6+ years leading and growing engineering teams in Fintech and Consumer Tech. Track record of owning end-to-end delivery, managing engineering budgets, and building high-performing teams from hiring through mentorship. Proven ability to architect fault-tolerant, high-throughput distributed systems — and the organisational discipline to ship them reliably at scale.

• My development workflow with an agent loop

  How I now work on my side project: I write the issue, label it, and an agent loop running on my laptop works on it, verifies it and opens a PR for me to review.
• Partial Indexes in Postgres

  How partial indexes work in PostgreSQL, when they earn their keep, and how to create one.
• Tips to stay hands-on as Tech Lead/Manager

  Practical ways to keep writing code and stay technically credible after moving into a lead or manager role.

Projects

• Flostepflostep.dev

  Interactive system-design diagrams you can step through one interaction at a time, rather than pointing at a static picture. Build by drag-and-drop or from plain text, share as a read-only link, and embed anywhere.
• agent-loopgithub.com/pandurang90/agent-loop

  An open-source background coding agent that runs on your own machine. Label a GitHub issue, and it works on it with Claude Code in an isolated git worktree, reruns your own checks, and opens a PR. Label the PR after review, and it addresses your comments.
