## Headline

Backend Software Engineer \| Go · AWS · Distributed Systems \| Fintech infrastructure @ scale \| ACM ICPC Regionalist

## About

I build backend systems that don't break under load\. At KFin Technologies — one of India's largest financial registrars – I've shipped production infrastructure in Go and Node\.js handling large\-scale financial data: streaming PostgreSQL exports directly into AWS S3 multipart uploads to cut peak memory by \~80%, replacing a blocking query frontend with an async Lambda \+ Athena pipeline, then re\-architecting it with AWS Step Functions to bring pipeline reliability from \~80% to 85% and cut failed\-job debugging time by 60%\. On the frontend side, I've solved performance problems at a systems level — designing a virtualised table component for 10,000\+ row datasets that drove a 90% DOM reduction and 40–50% latency improvement\. My stack: Go · Node\.js · TypeScript · React · PostgreSQL · AWS \(Lambda, Step Functions, S3, Athena\) · REST APIs\. I'm drawn to distributed systems, cloud\-native architecture, and performance engineering — problems where correctness and scale both matter\. Currently looking for backend or platform engineering roles where I can own infrastructure end\-to\-end\. Open to remote and India\-based opportunities\.

## Work experience

Software Engineer at KFin Technologies Ltd\., Jun 2024 \- Present · 2 yrs 1 mo, Hybrid, Eliminated server memory bottlenecks on large\-scale exports by implementing PostgreSQL COPY streaming piped directly into AWS S3 multipart uploads via Go — reducing peak memory usage by approx\. 80% and enabling streaming of datasets exceeding available server RAM\. • Built an asynchronous AWS Lambda \+ Athena workflow with PostgreSQL job tracking and S3 event notifications for status updates — eliminating frontend blocking on long\-running queries averaging 3–8 minutes\. • Scaled a high\-volume financial reporting pipeline from a brittle Lambda chain to an orchestrated AWS Step Functions workflow — managing Athena query state, retries, and S3 event transitions\. Improved end\-to\-end pipeline reliability by 5pp and cut failed\-job debugging time by \~60% via structured execution logs in Go\. • Improved frontend API maintainability by implementing Axios interceptors for centralised token management and global error handling — consolidating 3 separate auth implementations into 1 and reducing per\-request boilerplate by approx\. 40%\. • Drove an approx\. 90% DOM reduction and 40–50% latency improvement by owning the design and implementation of a virtualised table component for 10,000\+ row financial datasets\.

Software Engineer at KFin Technologies Ltd\., Dec 2023 \- Jun 2024 · 7 mos, On\-site, • Optimised initial load performance by 40% through lazy loading of landing page components, ensuring on\-demand content delivery\. • Streamlined state management with Redux Toolkit, reducing re\-renders and improving data flow efficiency\.
