What I'm looking for

I seek a role where I can lead full‑stack and AI/blockchain projects, work collaboratively with stakeholders, and build scalable, user‑centered products while continuing to grow technically.

I am a versatile senior software developer with deep experience building AI/ML models, blockchain smart contracts, and full‑stack e‑commerce platforms that prioritize scalability, performance, and user‑centered design. I have delivered marketplace and payment integrations, redesigned front ends for speed and UX, and integrated AI conversational features and image upload/live preview capabilities to improve conversion and reliability.

My background spans Next.js/Nuxt.js front ends with .NET backends, Node.js ecosystems, Solidity/Solana smart contracts, and cloud/DevOps workflows; I have led data projects in healthcare and finance to automate workflows, improve predictions, and speed decision making. I am committed to clean, maintainable code, effective stakeholder collaboration, and continuous learning to drive measurable business impact.
