Harsh kumar Khatri — Software Engineer

“Persistence is very important. You should not give up unless you are forced to give up.” – Elon Musk This principle strongly reflects how I approach my work, as a Senior Full Stack Engineer and Flutter Educator, focused on building reliable, scalable software that delivers real-world impact. With 4+ years of professional experience, I specialize in designing high-performance backend systems using ASP.NET Core (.NET 9) while also building modular, scalable Flutter applications. I’ve architected and shipped enterprise-grade products serving 900k+ users, working across startups, product teams, and freelance engagements, often owning systems end to end, from architecture and performance optimization to deployment. On the backend, I enjoy solving hard problems around scalability, data access, and reliability, optimizing APIs with Dapper, designing hybrid database architectures, building real-time analytics pipelines with ClickHouse, and setting up CI/CD workflows for zero-downtime releases. On the mobile side, my Flutter experience helps me design APIs that are practical, efficient, and client-aware. Beyond building products, teaching has been a major part of my journey. I’ve been educating developers for 3+ years, creating Flutter courses and learning resources that have reached 54,000+ students on Udemy, along with technical content on my YouTube channel Hexhybrids and my Medium blog. I strongly believe in community-driven learning and enjoy sharing lessons learned from real production systems, not just theory. I thrive in collaborative environments and bring a strong sense of ownership, logical thinking, and problem-solving to everything I do. Whether it’s writing clean architecture, mentoring developers, or creating technical content, my goal is to build impactful solutions and help others grow along the way. Outside of work, you’ll usually find me exploring new ideas, creating content, traveling, or simply unwinding with friends.

Jul 2020 – Dec 2022 · 2 yrs 5 mos

HackItShipIt was a part of the brand new summer hackathon league series which is organized by Major League Hacking and in this series, a hackathon is conducted every weekend.
I got a chance to be a mentor at HackItShipIt, which was a two-day hackathon, and this was a hell of an experience. I got to have a conversation with people from various different subcontinent and solve their doubts which made me learn and research new things. The MLH team was also great and was there to help mentors and participants. This was a change for me as well as I have always been a participant at a hackathon prior to this and now after being a mentor I got to know what all things are going there under the hood .
