About

Backend engineer with experience building scalable distributed systems and high-performance backend services. I’ve worked on designing systems that go beyond the happy path — handling failures, concurrency, and data consistency in real-world production environments. My work includes building asynchronous processing pipelines, optimizing high-scale APIs, and ensuring correctness in systems with complex state transitions. Some areas I’ve worked on: * Designing backend systems with clear architecture and service boundaries * Building asynchronous workflows using Redis and Celery * Solving concurrency issues such as race conditions, double execution, and inconsistent state * Optimizing APIs by improving query design and reducing unnecessary data transfer * Implementing reliable workflows with idempotency, retries, and fault-tolerant design I also have a strong foundation in data structures and algorithms, with a Top 5% global ranking (Knight) on LeetCode. Currently focused on deepening my understanding of system design and building scalable, reliable backend systems.

Work experience

Software Engineer at Shorthills AI, Nov 2025 - Present · 10 mos, India, Software Development Engineer — JumpIQ * Built a production-grade payment and subscription system from scratch, handling billing, retries, dunning, reconciliation, and webhook processing * Designed a gateway-agnostic architecture (Facade + Service + Gateway + Repository), enabling clean extensibility for future providers * Implemented reliable event processing using DB-first webhook persistence and asynchronous pipelines (Celery), ensuring zero data-loss under failures * Engineered a strict subscription state machine and idempotent workflows to maintain consistency across retries and partial failures * Solved critical concurrency issues (race conditions, double charges, TOCTOU bugs) using Redis-based distributed locks and atomic operations * Optimized high-scale analytics APIs (40+ endpoints), reducing latency by ~70% by eliminating unnecessary data transfer and improving query design * Designed a modular data processing pipeline (Strategy + Factory + Pipeline), enabling reusable and extensible analytics computation * Increased test coverage to production-grade levels (90–100%) and established platform-wide standards for logging, API contracts, and reliability
