Go orchestration over locally hosted language models: tool loops, structured output and retries, with nothing leaving the network. Built so small models can do useful work by being told the conventions instead of inferring them.

• Go
• Local LLMs
• Tool calling

Component APIs and house architecture rules served to coding agents over MCP, so generated code matches the codebase it is landing in rather than the average of the internet.

• MCP
• Go
• TypeScript

Forty-three standalone components. Variants compose as fragment directives instead of prop switches, defaults are injectable per application, and themes are pure custom-property layers. Published to a private registry.

• Angular 21
• Signals
• SCSS

Background workers classify PDF attachments, extract their fields with a quantised model on my own GPU, and record every decision exactly once so nothing is ever evaluated twice.

• Go
• Postgres
• Ollama

Go compiled to WASM driving raw WebGL2 — greedy meshing, hand-written shaders and a shadow pass, with the chunk protocol shared as one type between the native server and the browser client.

• Go
• WASM
• WebGL2
• GLSL

IMAP sync into Postgres that can be interrupted at any point and resumed without duplicating a message — because it will be interrupted, by servers that time out mid-fetch and mailboxes that renumber themselves.

• Go
• IMAP
• Postgres

OAuth2 and OIDC across every service, with token introspection in one Go middleware every handler embeds. No service holds a session, so any of them can be rescheduled without logging anyone out.

• OIDC
• Ory
• Go

Structured input rendered to print-accurate PDF in milliseconds — real kerning, real hyphenation, real bleed — instead of an HTML-to-PDF pipeline that breaks on the first long word.

• Typst
• Node
• Docker

OpenAPI to Angular services and models from a single static Go binary, so backend build images stop carrying a Node toolchain purely to emit TypeScript.

• Go
• OpenAPI
• Codegen

Medicover Sport is a platform that provides users with access to a wide range of sports and leisure activities. As part of a development team, I worked on the frontend of the Medicover Sport homepage using Angular, implementing and maintaining user-facing features based on provided designs and requirements. My work included developing reusable UI components, integrating frontend functionality, and ensuring responsive behavior across different screen sizes. I collaborated with other developers and team members throughout the development process to deliver and maintain a consistent, production-ready user experience.
