# Robin Singh Baran on Tal

## Headline

Backend Engineer · Python · Node\.js · FastAPI · Kafka · PostgreSQL · GCP \| Building distributed systems that scale

## About

I build backend systems \- APIs, distributed pipelines, and the infrastructure that keeps products running at scale\. Most recently: founding backend engineer at an AI startup, where I built the entire Python/FastAPI backend for a VS Code coding\-assistant from zero to closed beta in 4 months\. That meant OAuth integrations across GitHub/GitLab/Bitbucket, encrypted token storage, ML engine orchestration, Stripe billing, and GCP Cloud Run deployment \- solo\. Before that, 3 years at Tech Mahindra on a logistics platform handling \~100K daily transactions: \- Reduced API latency by \~30% through query profiling and database indexing \- Designed and built a fault\-tolerant payment pipeline using Kafka, AWS SQS/DLQ, and Redis \(idempotency, rate limiting, transient state\) \- cut operational errors by 37% \- Improved SLA adherence from 87% to 95% \- Cut Docker build times by 35% via Dockerfile layer restructuring\. I also built PulseQueue \- a distributed webhook delivery system with Kafka, async workers, exponential backoff, DLQ routing, Redis pub/sub, WebSockets, and Prometheus/Grafana observability across an 8\-service Docker Compose stack\. Built it to go deep on distributed systems fundamentals\. What I'm good at: → Python \(FastAPI\) and Node\.js backend systems → PostgreSQL, MongoDB, Redis, Kafka → AWS and GCP Cloud Run deployments → Building things that actually ship Open to: Backend Engineer / SDE / SDE 2 roles at product\-first companies\.

## Work experience

Full Stack Developer at Bajaj Finance, Sep 2026 \- Present · 1 mo, Bangalore

Backend Engineer at Code Gauge, Dec 2025 \- Apr 2026 · 4 mo, Remote, Built the entire Python/FastAPI backend for an AI coding\-assistant VS Code extension, from zero to closed beta in 4 months\. Designed the data layer: PostgreSQL for user, auth, and billing data; MongoDB for repo content and chunked code; deployed on GCP Cloud Run\. Built OAuth 2\.0 integrations for GitHub, GitLab, and Bitbucket to fetch private repos, with encrypted token storage and weekly token refresh handling\. Wrapped 3 ML engines into FastAPI services and orchestrated end\-to\-end request flow between repo ingestion, embedding generation, and the VS Code client\. Cut Cloud Run cold\-start by \~40% via Docker image slimming and lazy dependency loading; load\-tested ingestion pipeline with k6 against 2K GitHub profiles\. Built Stripe subscription backend with webhook\-driven plan activation, plus the full auth system: JWT sessions, signup/signin flows, and RBAC\.

Software Engineer at Tech Mahindra, Jan 2023 \- Dec 2025 · 3 yrs, Bengaluru, Reduced API latency by \~30% on a logistics platform handling \~100K daily transactions by identifying slow queries and overhauling database indexing strategy\. Diagnosed and fixed a race condition in the Order & Shipment service where concurrent requests caused duplicate processing via non\-atomic read\-modify\-write flows; resolved with DB\-level transactions\. Designed and built a fault\-tolerant payment pipeline using Kafka, AWS SQS/DLQ, and Redis for rate limiting, idempotency, and transient state — reducing operational errors by 37%\. Improved SLA adherence from 87% to 95% by monitoring API bottlenecks via CloudWatch and driving targeted backend fixes across the team\. Cut Docker build times by 35% by restructuring Dockerfiles to separate dependency installation from source layers, enabling aggressive layer caching\. Implemented JWT\-based auth with token rotation and OAuth 2\.0; wrote and contributed to Jest unit and integration tests across multiple service modules\.
