Full-stack software developer with over 7 years of professional experience delivering custom software solutions for clients worldwide. I specialize in building scalable, secure, and maintainable systems with a strong focus on performance, reliability, and clean architecture. My work includes developing custom Discord bots using Discord.js (v13–v14+), QuickDB, MongoDB, and REST APIs, as well as building backend services, automation tools, and monitoring systems using JavaScript, Python, C#, and C++. I also design and implement full-stack web applications, handling API development, database structure, and frontend integration. I have worked on complex systems such as ranked matchmaking and Elo systems, moderation and security tools, real-time trackers, and event automation solutions. In addition, I integrate third-party services and APIs including Riot Games, TMDB, Instagram monitoring, and EOS SDK-based systems. I work directly with clients to understand their requirements, provide clear technical guidance, and deliver production-ready solutions on time, while also offering ongoing maintenance, optimization, and post-delivery support to ensure long-term stability and success.
