What I'm looking for

I am seeking senior full‑stack or AI/Web3 engineering roles where I can lead technical delivery, mentor teams, work with modern cloud and LLM stacks, and build scalable, secure production systems.

I am a results-driven software engineer with 20+ years designing, developing, and deploying high-performance web, enterprise, AI, and blockchain solutions. I specialize in backend systems, intuitive frontends, and secure decentralized applications across multi-cloud environments.

My work spans full‑stack architectures using Python, JavaScript/TypeScript, React, Angular, Node.js, .NET, and FastAPI, and includes LLM/AI integrations, smart contract development, and scalable CI/CD pipelines. I have delivered measurable performance improvements, built reusable components, and engineered multi-cloud deployments for production systems.

I thrive in Agile teams, mentor developers, and focus on reliable, secure, and data-driven systems that solve real business problems. I seek roles where I can drive technical excellence and deliver impactful, production-ready solutions.
