Software Engineer @Heizen(backed by Titan capital) · Building scalable backend & real-time systems (Rust, Node.js, Nextjs, Nestjs, AWS)

About

I’m a Software Engineer focused on building scalable backend and real-time systems used by thousands of users in production. I’ve worked across the stack, but my core strength lies in backend architecture, system design, and performance-critical services. I’ve worked and maintained systems serving 100k+ monthly users, processing 2000+ TPS, and managing 100K+ records with reliability and low latency. My day-to-day work involves designing secure APIs, real-time services using WebSockets, and cloud-native applications on AWS. I’ve integrated payment systems (Stripe, PayPal, JustPay), worked with distributed data stores (PostgreSQL, MongoDB, Redis), and deployed production workloads using Docker and Kubernetes. I enjoy working on problems where scale, performance, and correctness matter, and I like taking ownership end-to-end — from design and implementation to deployment and monitoring. Open to connecting and discussing backend engineering, system design, and building real-world scalable products.

Work experience

Software Engineer at Heizen, Sep 2025 - Present · 10 mos, Hyderabad, Designed and developed production-grade backend services using NestJS, TypeScript, and AWS, supporting core product workflows. Built secure and scalable REST APIs, focusing on performance, reliability, and clean service boundaries. Integrated Stripe payments and handled transaction flows with proper validation, error handling, and observability. Worked on deploying and operating applications on Vercel and AWS, collaborating closely with frontend and product teams. Took ownership of features end-to-end, from requirement clarification to production rollout and post-deployment fixes.

Software Engineer at Curious Business Solutions, Jan 2025 - Sep 2025 · 9 mos, Bengaluru, Engineered high-performance, fault-tolerant backend services at CBS, focusing on multi-region payment processing and blockchain signature systems. Utilizing Rust (Actix-web, Tokio), I architected microservices capable of handling 2000+ TPS with sub-millisecond latency. A key achievement involved building a robust integration layer for Razorpay, where I implemented idempotent request logic and atomic state transitions to ensure zero-loss transaction integrity.

Full Stack Engineer at Build in Bharat, Jun 2024 - Jan 2025 · 8 mos, Delhi, India, Developed Robust backend system and User Friendly UI
