What I'm looking for

I seek senior engineering roles where I can lead cross-functional teams to build scalable web, e-commerce and Web3 products, delivering measurable business outcomes in collaborative, product-focused environments.

I am a Senior Full-Stack Engineer with over 8 years building scalable web, e-commerce, and blockchain solutions using the MERN stack, Python, Shopify, and Web3 technologies. I specialize in React, Next.js, Node.js, Django, Solidity and AWS to deliver mobile-first and high-traffic platforms.

I have delivered AI-powered chatbots (Python & OpenAI), a sports betting platform serving 35k+ users, Shopify theme and app customizations that increased sales by 25%, and deployments to AWS that cut operational costs by 15%. I also built mobile apps that boosted user engagement by 30% and job applications by 35%, handled 1M+ API requests daily while reducing server load by 35%, and improved backend efficiency by 20% through GraphQL and Apollo collaboration.

I lead and collaborate effectively in cross-functional, remote, and freelance teams, favouring pragmatic, measurable solutions. My goal is to foster strong team collaboration and turn client ideas into high-impact digital products that drive business results.
