What I'm looking for

I’m seeking full‑stack or backend roles where I can build scalable SaaS, IoT, or blockchain systems, mentor teams, and improve cloud and DevOps practices.

I am a full‑stack developer with over eight years of experience delivering scalable web, mobile, and enterprise solutions across SaaS, eLearning, blockchain, IoT, and online gaming industries. I focus on building reliable systems using modern technologies like JavaScript/TypeScript, React, Node.js, Nest.js, PHP (Laravel, Symfony), PostgreSQL, MongoDB, and AWS.

I have led backend and full‑stack work — developing custom CMS and website builders, designing IoT dashboards and GPS/LoRa tracking systems, and implementing SCORM/LMS integrations. I delivered off‑chain infrastructure for blockchain‑integrated platforms and optimized cloud deployments and APIs for high‑traffic systems.

I’m known for progressing from junior to senior roles, mentoring junior developers, and consistently producing maintainable, scalable solutions with an emphasis on security, trust, and long‑term value.
