I'm the kind of developer who opens the network tab before the design file. I like systems I can see into: traces that explain where the time went, caches that know when to step aside, and pages that render before you finish blinking.
I started out building UI components. Over time I took on the layers underneath them: server rendering, runtime, caching, telemetry and the infrastructure the whole thing runs on. Today I spend most of my time where a slow request turns into a good question.
Enterprise web platform. I'm a contractor on the global web platform of a large industrial company. It's one big SvelteKit monorepo that serves marketing pages, a help center, a product catalog and a B2B partner portal across dozens of countries and languages, including right-to-left. I joined to build CMS-driven components. Now I own performance, observability and much of the runtime underneath:
- brought in OpenTelemetry end to end in server rendering, with telemetry config that changes at runtime without a redeploy
- moved the app to Bun on Kubernetes with a custom multi-worker server, and found every place where Bun and Node quietly disagree
- built a Redis/Valkey caching layer with an in-memory L1, pipelining, cluster mode and a latency-aware circuit breaker
- shipped SSR islands for the global header, so the page hydrates only what needs to be interactive
- hunted down memory leaks, trimmed the bundle with lazy component loading, and ran production performance audits (TTFB, LCP, payload, cache) that ended in fixes, not slides
- made failures readable: precise upstream errors, request IDs that tie logs together, and pages that survive when one component fails
E-commerce in-house. I'm the developer and product owner for a fashion brand that sells in two markets. I build integrations between the store, order management, warehouse and accounting, plus a data layer that gives every dashboard one shared definition of revenue. The storefront is mine too.
Freelance. Custom storefronts and Shopify apps for brands, built pixel-perfect from Figma.
Just for fun. Small tools I build because I want them to exist, like an offline-first training app that runs on my phone every day.
- Following a span through three services and a queue until the bug has nowhere left to hide
- Turning "it's slow sometimes" into a graph, a cause and a fix
- Hydration puzzles: Svelte 5, web components, shadow DOM, all on one page
- Workers, retries and idempotency, so nothing gets lost when the network doesn't cooperate
- Front-ends that feel instant on a mid-range phone, not only on my machine

Currently tinkering with: SvelteKit 3, and AI agents that write specs before they write code.
