I'm a technical problem-solver, an accomplished backend engineer well-versed in Java, AWS, and a spectrum of databases including PostgreSQL, Redis, and MongoDB. I bring a wealth of expertise in designing and implementing robust distributed systems with a proven track record of applying microservices architecture and domain-driven design principles to large-scale scale highly complex business domains.

As an engineer with a "shifting left" mindset, I emphasize writing clean code with highly efficient and mature unit tests. I follow modern software design principles, leverage cloud services and deliver solutions that adhere to 12-factor methodology which are very easy to maintain and operate at scale on the cloud.

I am also an effective team player, I have led more than 20 engineers across 4 different teams and successfully delivered 10+ projects. My biggest achievement as a team lead is to deliver a product on Java, Postgres, Redis and AWS stack that is used by 40,000 employees of a Fortune 500 company with zero downtime and <150ms p95 response time across 40+ APIs and I have successfully secured highly sensitive personal information of the employees in a way that passed Google Madiant Pen Test, AWS Security Audit and the Company's internal CS Audit.

My primary programming stack is Java and Spring Boot, however, I have also developed solutions on the serverless stack using NodeJS and GoLang. Besides software development, I love to challenge myself to solve algorithmic problems that often require advanced data structures to process a large dataset under strict time constraints. Starting from 2009, I have solved 2000+ problems in 10+ platforms e.g. Topcoder, Codeforces, LeetCode, UVA, URAL, USACO etc and participated in 300+ online competitions and 50+ onsite competitions. You can learn more by following my online profiles below -

I also love continuously educating myself by taking online courses from Udemy and doing Certifications. I am currently 4x AWS certified and Kubernetes Certified Application Developer.

Occasionally, I do small fun projects to explore new domains e.g IOT/Machine Learning/Big Data. Here are two of my noteworthy projects -
