👋 Hi, I'm Javi

a dedicated software engineer, currently based in the vibrant 😏 city of Helsinki 🇫🇮, but ready to pack 🧳 and head over my next destination 🏝️ (which I really hope will be a warmer one 🌞)

For the last couple of years, I've been paying the bills 💸 by working as a full-stack web developer at a fintech startup, writing RESTful APIs using TypeScript, and crafting intuitive UIs with React, all that powered by the Azure cloud.

When I'm not conjuring full-stack magic, I'm teasing AI, writing shell scripts until they grow too long, and have to port them to Python 🐍, or hacking through the Web3/blockchain jungle 🐒. Apart from my school and professional experience, I've been playing with tech for as long as I can remember 👴🏻, and have experience in lots of other languages (C, Golang, etc).

Aside from programming, I enjoy cooking 🍳, working out 🏋🏻, and drawing 🎨. I'm also a big fan of music, and movies.

Things I can do for you

Integrating AI Into Your Business

Lately I’m more focused on integrating LLMs into real businesses, so they can benefit from the AI revolution. I work comfortably across TypeScript-based AI frameworks such as the Vercel AI SDK, Mastra, and Copilot Kit. I’ve also built demos with the MCP TypeScript SDK, though frameworks typically help ship faster in production.

• MCP tools + streaming: implement MCP tool integrations (schemas, auth, error handling) and real-time streaming for responsive UX.
• Agent building: design instructions, tool-calling policies, and function routing with resource/thread-scoped memory and working-memory templates.
• Workflow orchestration: chain agents and tools into multi-step flows with parallelism, conditional branches, retries, and context assembly.
• Context window management: conversation history, semantic recall (vectors/embeddings), and structured working-memory templates.

Full-Stack Skills

Product-oriented engineer working mostly with TypeScript, React, Node.js, and some Azure cloud.

• TypeScript + Node.js: APIs, background workers, CLIs.
• React: React-router, Zustand, ShadCN, Tailwind CSS, MUI.
• Azure: Functions/App Service, Azure OpenAI, Table and blob storage, basic infra.

About the Site

Oh, by the way, this site is SSGed with Astro, but all the styles, and code (pagination, scripts, etc) have been written by yours truly, from scratch 😉.
