About

"Building impactful software, empowering teams, and driving innovation—these are the pillars of my career." I am a seasoned software engineer with over 10 years of experience in distributed full-stack product development. My expertise encompasses end-to-end system design, including High-Level Design (HLD) and Low-Level Design (LLD), to create scalable, high-performance systems. I leverage my deep understanding of data structures and algorithms to solve complex problems and deliver robust solutions tailored to user needs. At PayPal, I spearheaded initiatives that enhanced customer experience and reduced support team contact rates by 29.6%. My work involved designing microservices, optimizing system architecture, and mentoring developers to foster skill growth and team efficiency. Beyond corporate roles, my entrepreneurial ventures have honed my ability to blend strategic vision with technical execution—boosting team productivity, accelerating growth, and launching impactful products. As I continue to evolve in my career, I’m excited about stepping into a Software Architect role, where I can align my expertise in HLD, LLD, and distributed systems with strategic leadership. My goal? To lead the creation of resilient, cutting-edge software systems while inspiring the next generation of developers. When I’m not immersed in code or architecture diagrams, I enjoy exploring new advancements in distributed systems, sharing knowledge with peers, and tackling exciting side projects. Let’s connect to exchange ideas and collaborate on building the future of technology.
