Software Engineer II building scalable Node.js, TypeScript, AWS, and full-stack systems for travel-tech and fintech.
IndiaWhat I'm looking for
Software Engineer II with nearly 4 years of experience building scalable backend and full-stack products for travel-tech and fintech. I work across Node.js, TypeScript, React, Angular, AWS, REST APIs, microservices, distributed systems, payments, event-driven architecture, and observability.
At udChalo, I built end-to-end payment collection covering customer UI, payment orchestration, webhooks, retries, recovery, reconciliation, and notifications. I led distributed Node.js microservices that reduced peak-traffic latency by 25%, developed APIs that reduced average response time by 30%, and delivered a hotel platform supporting inventory, bookings, an agent dashboard, and SEO management for 10,000+ landing pages.
I also built airline NDC integrations and real-time flight notifications, automated incident response to reduce MTTR by 40%, improved monitoring while saving approximately USD 3,000 annually, and led a Redis Enterprise migration and Node.js upgrades that saved approximately USD 1,000 monthly. I enjoy solving reliability, performance, integration, and product-delivery problems end to end.
Recognition includes the Star Performer Award (2025), Project of the Year for Price Drop Assurance (2024), the Rising Star Award (2023), and multiple Rookie Rockstar awards.
