About

I am a Software Engineer with 2.5+ years of experience building highly scalable, distributed backend systems for the FinTech industry. Currently, I develop enterprise financial solutions at Q2, focusing on high-throughput payment architectures, complex REST API integrations, and operational reliability. Previously, I worked as a Software Development Engineer Intern at Amazon, where I optimized backend microservices and improved data processing throughput. I thrive on owning the end-to-end software development life cycle (SDLC), enforcing secure coding standards, and tackling complex system design challenges under strict memory and resource constraints. Core Tech Stack: 💻 Languages: Java (21, 8+), Python, Apex, SQL ⚙️ Backend: Spring Boot, RESTful APIs, Spring Data JPA, Node.js ☁️Cloud & DevOps: AWS, Docker, CI/CD Pipelines 🗄️ Databases & Caching: PostgreSQL, Redis, NoSQL Architecture: Distributed Systems, Microservices, Low-Level Design (LLD)
