What I'm looking for

I seek a customer-focused company where I can lead development of web, mobile, and blockchain solutions, drive automation, and improve customer retention through scalable, innovative software and collaborative teams.

I am a results-driven senior software engineer with over a decade of experience building web, mobile, and blockchain solutions. I have led full‑stack projects using React, core PHP backends, AWS, Docker, CI/CD pipelines, and developed NFT marketplaces and smart contracts across Ethereum, BSC, Solana, Avalanche, Polygon, and Cosmos.

I automate processes to reduce overhead and accelerate growth, having improved internal systems for rapid business expansion and built integrations like ad API reporting, high-performance web crawlers, and client self-serve portals. I work well in Agile teams and enjoy mentoring, leading technical efforts, and delivering customer-focused products that improve retention and efficiency.
