Clients
US, EU & AU Clients
Full-stack engineer with 8+ years building production systems for startups and product teams in the US, EU, and beyond — spanning backend, frontend, cloud infrastructure, AI pipelines, and Web3. I work with PHP/Laravel, Python/Django/FastAPI, and Node.js/NestJS on the backend, and React, Next.js, Vue, Nuxt, and Svelte on the frontend.
I deploy with Docker, Kubernetes, and CI/CD pipelines on AWS and GCP, integrate payment systems like Stripe, PayPal, and iDEAL, and build AI features using RAG with LangChain, OpenAI, and Pinecone. On Web3, I write and ship Solidity smart contracts on Ethereum and integrate them with frontends via Wagmi and ethers.js.
I’ve led small development teams, set code standards, and mentored junior developers while staying hands-on — owning everything from spec to deployment. Open to remote, part-time, or project-based engagements with startups and scaling teams in Australia, Europe, and North America.
