At Aspora \(Sequoia / Greylock / YC\-backed\), I work on the infrastructure moving $2B\+ in annual remittance volume for 800K\+ NRIs — primarily in Go and Java/Spring Boot\. I'm drawn to the hard parts of backend — low\-latency services, async workflows, and distributed systems\. A few things I've built: • A Go user\-segmentation service powering platform\-wide cohort routing at p99 <15ms across 3\.7M\+ requests, zero errors\. • A Debezium → Kafka CDC pipeline that cut attribute\-propagation latency from minutes to <10s across 1M\+ daily events\. • Outside work: an LLM\-powered log\-triage service that correlates Kafka logs by trace ID and proposes root\-cause hypotheses, and a Go ad\-targeting engine running at 8\.4K RPS, p99 35ms\. Day to day I live in Go, Kafka, PostgreSQL, Redis, Temporal, and Docker — and I'm increasingly interested in AI\-driven tooling for debugging and automating backend systems\. ## Location Bengaluru ## AI stack claude code claude claudecode ChatGPT Devin LM Studio ## Work experience Software Engineer \- Backend at Aspora \(formerly Vance\) \| Sequoia, Greylock, Y Combinator – backed, Nov 2025 \- Present · 9 mo, Bengaluru, Karnataka, India, – Backend engineer at a remittance fintech processing $2B\+ annual volume for 800K\+ NRIs; authored 7\+ design docs reviewed by senior leads, shipped on 2 product launches, mentored interns, and collaborated cross\-functionally across Go and Java/Spring Boot\. – Solo\-built backend for the Activation Stepper – a 3\-step home\-screen onboarding widget driving users from KYC to first transfer; delivered \+4pp Order Completion lift \(\+10\.4pp on iOS, \+15\.4pp on referred users\) across UAE/UK/EU/US within first week of launch\. – Shipped backend for the NRE/NRO Bank Account launch – NRIs open an Indian bank account in <10 min \(vs\. industry\-standard 1–2 weeks\); built the KYC document\-normalization pipeline \(image → notary\-compliant PDF\), remote online notarization flow, and biometric/MPIN auth setup; onboarded 100s of users in month one\. – Solo\-built a Go user\-segmentation service from scratch powering platform\-wide cohort routing at p99 <15ms and p50 <2ms with zero errors over 3\.7M\+ requests; authored the system design doc and shipped end\-to\-end with a hot\-reload rule engine, unlocking a new product launch\. – Architected a Debezium → Kafka CDC pipeline from inception, replacing legacy polling\-based aggregation and cutting user\-attribute propagation latency from minutes to <10s across 1M\+ daily events\. – Proposed and led PII field\-level scoping rollout on a Spring Boot CRM serving sensitive customer data – plan\-based masking, full audit logging on data access, and outbound\-call masking; passed internal security audit across admin surfaces\. – On\-call across backend services; root\-caused and patched a cross\-environment config drift bug breaking the free\-transfer reward flow and resolved an MSK consumer\-lag outage, restoring a key acquisition feature mid\-hotfix\.
