About

I build backend systems that handle real money and real risk at scale. At Ethos Life, I've shipped 4+ insurance product launches covering 100K+ policies annually — owning everything from system design to production war-room releases. I've migrated core business logic out of monoliths, architected microservices from scratch, and stepped up as a de facto lead when needed. At Wells Fargo, I worked on enterprise investment banking systems — building real-time market data streaming with SignalR, improving coverage on a 125K+ LOC codebase, and transitioning infrastructure from Solace to Kafka. What I care about: systems that are correct under pressure, APIs that don't surprise you at 2am, and teams that ship with ownership. Stack: NestJS · Kafka · PostgreSQL · .NET Core · TypeScript · AWS Looking for: SDE-2 roles at product-driven companies where backend complexity is a feature, not a bug.

Software Engineer

Sep 2024 – Present · 1 yr 8 mos · Bengaluru, Karnataka, India · On-site

Designed and delivered Agent of Record (AOR) functionality end-to-end — implemented agent validation and contracting workflows, led standups, maintained documentation, and drove the project to completion independently in the absence of the lead.
Played a key role in the IUL Cross-Choice product launch in California (one of the company's highest-revenue states) — implemented bundling logic and coordinated QA in a war-room style rollout, contributing to 100K+ policies annually.
Architected an explainability module within the Product Routing Service (PRS) to surface transparent, auditable reasoning for product eligibility decisions — improving trust for both agents and end users.
Migrated premium and code calculation logic from the monolithic application to the Product Config Service (PCS) using spreadsheet-driven configurability — reducing dependency on the main app and improving long-term maintainability.
Contributed to 3 core microservices (PRS, PCS, Profile Service) — added AD support, PCS enhancements, and routing optimizations that directly unblocked multiple product launches.
Implemented replacement letter functionality for the Spirit product and contributed to TrueStage policy onboarding and AD policy bundling, ensuring smooth, on-time launches.
Onboarded 2 engineers (1 junior, 1 incoming lead) with end-to-end knowledge transfer across 5+ microservices and product flows — structured documentation and KT sessions cut ramp-up time significantly.
Handled critical production incidents (P0/PNOTs), releases, and cross-team coordination independently — consistently delivering features across insurance products, policy admin, and microservices teams.
