About

Senior backend engineer with 8+ years building distributed systems for fintech and B2B SaaS. Owns a multi-tenant workflow orchestration platform top to bottom — a custom execution engine with recursive workflows and rollback, the handler services behind its step primitives, and the customer-facing Workflow Builder on top — running as shared infrastructure across 3 services at ~1,000 runs/day, while leading a small team. Core stack: TypeScript, PostgreSQL, Redis, AWS.

SDE 3 at Neuron7.ai, Nov 2024 - Present · 1 yr 10 mos, Bengaluru, Owned multi-tenant workflow stack top to bottom — built the custom execution engine (shared infrastructure, ~1,000 runs/day across 3 consumer services) and Customer Workflows, the customer-facing product, including its visual workflow Builder, on top of it. • Designed the engine from scratch: recursive (nested) workflows, rollback/compensation mechanics, and developer-facing handler interfaces, with composable step primitives — Assignment, Notification, Integration (ERP pull/push), and AI Enrichment. • Built the User Tasks Service (human approval/general-task assignment) from the ground up and re-architected the brittle legacy Notifications and Integrations services into reliable step handlers. • Led a team of 3 engineers — owned architecture, delivery, and code reviews — and shipped the Dev Kit documentation other engineers build against.

Senior Software Engineer at Rattle, Mar 2023 - Oct 2024 · 1 yr 8 mos, Bengaluru, Built Project Board from scratch — a Salesforce data visualization product. Owned backend API design, coordinated frontend integration (React, Next.js), shipped iteratively from MVP through production, and continued expanding the product surface based on customer feedback. Architected backend services in Node.js and NestJS with multi-layer caching, reducing API response times by 65% and page load times by 50%. Set up Docker-based microservices on AWS ECS with Nginx and ALB, built CI/CD pipelines via GitHub Actions, and defined auto-scaling policies. Tech: Node.js, NestJS, Python, AWS ECS, Docker, Nginx, ALB, GitHub Actions

SDE II at slice, May 2021 - Mar 2023 · 1 yr 11 mos, Bengaluru, Built two platform-level microservices — a Document Management Service (encrypted KYC document storage and retrieval with retention policies) and a Credit Reporting Service (durable credit bureau data ingestion, storage, and report generation) — both serving as shared infrastructure consumed by multiple downstream services. Rebuilt Jenkins deployment pipelines for reliability and configurability, achieving zero-downtime deployments. Revamped user onboarding backend — built experimentation infrastructure for A/B testing that drove 25% engagement increase and 18% drop-off reduction. Tech: Node.js, Express, TypeScript, PostgreSQL, MongoDB, Redis, AWS SQS, AWS ECS, Jenkins

Software Engineer at Pratilipi, Aug 2019 - May 2021 · 1 yr 10 mos, Bangalore, Developed high-performance APIs with Python/Flask, Node/Express, and GraphQL, serving 500K+ daily requests. Migrated monolithic Python services to cloud-native microservices on AWS ECS, improving performance by 40% and resource utilization by 60%. Tech: Python, Flask, Node.js, Express, GraphQL, PostgreSQL, AWS ECS
