Summary
👤
Senior🎓
Top SchoolPriyanshu Jain is a Principal Engineer and platform builder with 11 years of engineering experience and nine years focused on distributed systems and payments at scale, currently shaping infrastructure for a YC-backed fintech serving 3M+ merchants. He’s the senior-most IC at OkCredit, where he led architecture and delivery that scaled payments from $2M to $20M monthly, slashed UPI payout latency from 30 minutes to 15 seconds, cut cloud costs by 40%, and drove ISO 27001–grade security and compliance work. A hands-on systems thinker, he built large-scale migration tooling (10B+ rows), moved microservices to fully automated testing, and created developer CLIs and log-analysis automation that halved on-call tickets. He co-founded and led engineering at multiple startups, bringing a product-first pragmatic approach—favoring simple, well-understood tools over trend-chasing—and he mentors engineering teams while fostering psychological safety. Currently experimenting with autonomous property-based testing using LLMs at 73ai, Priyanshu blends research-driven curiosity with production-hardened experience in regulated, high-throughput domains.
