Senior software engineer building scalable, low-latency cloud-native banking platforms.
IndiaWhat I'm looking for
I’m a Senior Software Engineer with 6.5+ years of experience building highly scalable, high-throughput, low-latency distributed applications. I bring a product-minded approach—collaborating with business and product teams to deliver technical solutions against stringent targets and deadlines.
Most recently, I’ve helped build cloud-native banking and operations platforms by spearheading greenfield KYC/KYB onboarding engines and creating AI-based automated Trust document extraction to reduce manual verification. I also led the migration of critical KYC/KYB workflows from AWS Step Functions to Temporal, improving reliability, observability, and resilience for long-running processes.
I’ve additionally driven large-scale distributed system work with Kafka-based event messaging at Paytm, including a Redis + Lua sliding-window API rate limiter that reduced third-party service costs and performance-focused tuning with ProxySQL. Earlier, at Cisco, I migrated legacy monoliths to microservices, improved response times, and strengthened observability through automated alerting; I’m recognized for both technical excellence and impact.
