About Me

Hello! I'm Chathura Uddeepana.

I'm a passionate Senior Software Engineer with 7+ years of experience in building practical, scalable, and impactful digital solutions.

My experience is strongly centered around full-stack development and blockchain development, supported by hands-on work in backend API development, database design, admin dashboards, automation workflows, cloud-based deployments, mobile application development, and Linux server environments. I have worked with technologies such as Angular, Next.js, Node.js, Express, MongoDB, REST APIs, iOS, Android, Solidity, Rust, blockchain technologies, and modern cloud hosting platforms. I also have experience building crypto-related blockchain solutions, including smart contracts, decentralized applications, and performance-focused backend systems.

Throughout my career, I have contributed to the design, development, and delivery of business-critical software systems. I have also had the opportunity to work as an Associate Tech Lead, where I supported technical decision-making, guided development work, and helped improve delivery quality within the team.

I enjoy learning deeply, solving complex problems, and turning ideas into reliable working products. My current interests include fintech, blockchain, AI automation, trading systems, and performance-driven backend development.
