Senior Front-End Developer with 10+ years of experience in JavaScript and TypeScript, building high-performance web and mobile applications in fast-paced, product-driven environments. Most recently, I led front-end development at a sports betting startup later acquired by a US-based fantasy sports company entering the betting market. I built and maintained high-load, real-time applications for internal and customer-facing use, focusing on performance, scalability, secure authentication, KYC flows, and third-party integrations, while collaborating closely with designers and backend engineers to deliver reliable systems under heavy traffic and business demands. In addition to web development, I have experience contributing to mobile development initiatives, including native Android work, allowing me to better understand platform-specific constraints and user experience considerations. I’m looking for a role in a collaborative, open environment where engineers are involved in product decisions, and I can contribute across web and mobile projects depending on team and product needs, while continuing to grow my mobile development expertise.
