The road so far
00KM — THE GUN
The start line
B.Tech in Computer Science, BIT Mesra, Class of 2022. Left campus with a degree, a CodeChef 4★ rating, and a pair of legs that refused to sit still.
10KM — SETTLING IN
The telecom years
Three years at Amdocs — Claro Chile, Vodafone Romania, Rogers Canada, PLDT Philippines. Learned what scale means: millions of records migrated, 15K transactions a day, uptime measured in nines.
21KM — THE TURN
Where it got serious
Past the half-marathon mark, running stopped being a hobby and became the profession: periodised blocks, double days, sleep guarded like a secret, every kilometre logged and reviewed.
30KM — THE SURGE
All-in on AI
September 2025: traded big-company comfort for startup pace at DBSync. Now building MCP servers and RAG pipelines — the plumbing that lets AI agents do real work. KM 30 is where races are decided; careers too.
42KM — THE A-RACE
Tata Mumbai Marathon 2027
Every alarm, every interval, every boring easy mile is a deposit toward one January morning on Marine Drive — sea on the left, PB on the mind.
THE OTHER 9 TO 5 — SHIPPING SOFTWARE BETWEEN SESSIONS
Built in sprints,
trained for distance
SDE-2 at DBSync, on the Cloud Workflow platform — Java and Python microservices syncing data across CRMs and ERPs. The fun part: building multi-tenant MCP servers and RAG pipelines on Milvus, so AI agents can actually use the tools instead of just talking about them.
Before that, three years at Amdocs keeping telecom systems honest across four countries. Big systems and long races reward the same things — show up daily, trust the process, let small gains compound. One pays the bills. The other sets the alarm.
