👋 Hi, I’m Abhilash Koliwad — a Senior Software Engineer with over 8.5 years of experience building and scaling backend systems across startups and large enterprises like HubSpot, Phasio(startup), and JPMorgan Chase. I specialize in backend software engineering, with a deep focus on distributed systems, data integrations, cloud infrastructure and asynchronous programming. Over the years, I’ve led end-to-end development of high-performance services, improved scalability through caching and architectural redesigns, and driven technical initiatives across teams. Along the way, I discovered my passion for mentoring - whether it’s career growth, prepping for interviews or cracking backend system design. If you’d like to discuss backend design or career growth in software engineering, I’d love to connect.
