What I'm looking for

Own Go and Python backend end to end. Real-time distributed pipelines, reliability with SLOs and observability, cost and performance work. Senior IC or tech lead at a small remote-first team. Async-friendly, design-doc-first culture. Full-time or contract.

Backend engineer with 9+ years in Go and Python. Based in Bangalore, open to fully remote roles worldwide, any timezone.

Most recently I spent five months solo building EVPanda (evpanda.io), an observability platform for EV charging networks. Shipped end to end alone: Go and Python backend, NATS ingest pipeline, custom rule engine with a DSL, capture SDKs in Go, Python, Node, and Java, and a VueJS dashboard.

Previously:

Engineering Lead at Ionage where I grew from the third engineer into leading a 12-engineer team owning the full EV software suite (CSMS, eMSP, Fleet, Payments) serving 10k+ chargers across 70+ operators.
Senior Software Engineer at Twilio (Segment) owning GDPR and BCR data-deletion pipelines and observability tooling across Personas destinations.
Senior Software Engineer at Instamojo where I led a zero-downtime OAuth2 migration to ORY Hydra, cut monthly AWS ECR cost by 75% and Mixpanel by 20%, and shipped a high-throughput SMS microservice handling 50k+ daily messages.

Strongest at distributed systems, real-time data pipelines, payments infrastructure, EV charging protocols (OCPP and OCPI), observability, and shipping 0 to 1 products end to end. Comfortable owning systems from protocol edge cases to production reliability.

Looking for senior IC, tech lead, or founding-engineer roles at small remote-first teams. Go and Python primary. Async-friendly, design-doc-first cultures preferred. Full-time or contract. USD compensation.
