About

From a lab in Rasht to design systems in Berlin.

I wrote my first real JavaScript in 2013, in a university lab in Rasht, trying to make a button do anything other than submit a form. A few years later I was building WordPress themes for local businesses, more than thirty of them, and learning the hard way that a page that takes six seconds to load is a page nobody reads.

The tools changed since then, from jQuery to React and Next.js, but the job did not: take something complicated and make it feel simple, then make it fast. I have led small teams in Rasht and Istanbul, shipped a student portal used across the UK, and today I work on AgyleOS, an HR platform where I own the design system and the performance of our heaviest dashboards.

Outside work I build TaleSelf, a story game for learning languages, and I am slowly getting better at German. Langsam, aber sicher.

  • 01

    Performance is a feature

    I set a budget before the first component and measure in the field, not only on my laptop. Users feel 2 seconds more than they read any copy.

  • 02

    Systems over screens

    Tokens, components and docs that let a team build the tenth screen faster than the first, and keep it looking like one product.

  • 03

    Accessible by default

    Keyboard paths, contrast and screen reader labels go in the first pull request. Retrofitting WCAG is always the expensive way.

  • 04

    Teams ship, not heroes

    Code reviews that teach, pairing when someone is stuck, and guidelines short enough that people actually read them.

TaleSelf

Learn a language by living inside a story where you are the main character.

Pick a language and a level, then read and listen to a branching adventure written for you. Every choice moves the story; the first player to open a new branch has it written by an LLM, and every player after them reads it with their own name and character. Streaks, chests, weekly leagues and a word ladder keep people coming back.

  • 22languages to learn
  • 9app languages, RTL too
  • 1story, shared by every player
  • Flutter
  • TypeScript
  • Fastify
  • PostgreSQL
  • Drizzle
  • Gemini on Vertex AI

Meet the cast

No images here: every character is drawn in code from a look (hair, skin, shirt, eyes). Flutter paints it in the app, SVG draws it on the web. Each one greets in a different language, in the voice the app ships with. Move your pointer, then click one to hear it say hi.

What I bring

Senior means the whole picture.

Pixels are the visible part. Most of the value is in the decisions around them.

  • 01

    Frontend architecture

    Folder structure, data flow, rendering strategy and the boring decisions that keep a codebase easy to change in year three.

  • 02

    Design systems

    Tokens, accessible components, Storybook docs and a release process designers and engineers both trust.

  • 03

    Performance work

    Caching, code splitting, render profiling and Core Web Vitals. I like a chart that goes down and to the right.

  • 04

    Auth & enterprise

    SSO with Keycloak or OAuth2, role-based access and multi-tenant UIs that hide what people should not see.

  • 05

    Testing culture

    Unit, component and end-to-end tests that catch real regressions without slowing every pull request.

  • 06

    Leading & mentoring

    Reviews, pairing, onboarding docs and hiring loops. Most of my best work is code other people wrote.
