What I'm looking for

I'm open to relocation and looking to lead hands-on engineering teams building scalable backend and distributed systems, while strengthening delivery, experimentation, reliability, and people growth.

I've led engineering at Adpushup, a B2B ad-tech SaaS company, scaling the team from 7 to 30 engineers while delivering $500K+ in recurring annual savings through platform re-architecture, cloud migration, and database optimization.

I build and improve high-volume systems hands-on, including an ETL pipeline processing 30B+ events monthly that cut processing time by 60% and saved more than $300K annually. I also improved a FastAPI and SQLAlchemy reporting API, reducing analytical query latency by 50–90%.

I create durable engineering organizations through product-aligned pods, structured coaching, clear ownership, and data-driven experimentation. I developed engineers into team leads, reduced engineering escalations by about 30%, and helped achieve 99%+ SLA compliance for critical support issues.

Earlier, I led remote teams at Ideagist, built NFC-based mobile products at Tap A Phone, co-founded Codebrew Systems, and contributed to a bus-ticketing distribution system at Travelyaari.
