## 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\.
