About Me
Get to know me and my professional journey.
Senior Software Engineer — Mobile & Full-Stack Web
I am a Senior Software Engineer with around 4.5 years of experience specializing in both high-performance mobile application development and enterprise-grade full-stack web applications.
My expertise spans building native Android and smart POS ticketing applications (Java/Kotlin, SQLite, payment gateways) as well as architecting modern web platforms, online printing marketplaces, and billing SaaS applications (React, Next.js, REST APIs).
I focus on writing clean, maintainable, and highly secure code, executing VAPT audit requirements, optimizing performance, and delivering robust offline-first and cloud synchronization systems that serve millions of transactions daily.
Passionate about pushing the boundaries of technology, I thrive on solving complex engineering challenges and transforming ideas into scalable, production-ready products that make a real impact.
