02.About

Architect turned developer

Full-stack developer based in Stockholm. My background in architecture gave me a structural eye that shapes how I approach software — from system design to UI detail.

I've shipped production systems across React + FastAPI, Angular, .NET, and MERN stacks — including ApplyLuma, an AI job-search SaaS, Rostid, an e-commerce platform with 400+ automated tests, and DeskFlow, an IT helpdesk with SLA tracking and a grounded AI assistant. On the data side, I built liftpipe, a dbt + DuckDB + Dagster pipeline with an in-browser DuckDB-WASM dashboard, and Bostadspuls, a housing market analytics platform on BigQuery. I also integrated Swedish BankID into a recent project — a niche but valuable skill in the Swedish market.

I care about owning problems end-to-end and building things that hold up in production.

Full-Stack ITSM

DeskFlow

IT Helpdesk & Asset Management Platform

A small ServiceNow-style service desk: tickets with a status workflow and SLA timers, a hardware inventory, a Markdown knowledge base with Postgres full-text search, an append-only audit log, and an optional AI assistant that only answers from published articles. Angular front end, async FastAPI back end and a background worker, containerised and deployed on Railway.

SLA engine: per-priority response/resolution targets, clock paused while Pending, worker flags at-risk and breached tickets
Single source of truth for SLA rules — API, dashboard, filters and worker can't disagree
Grounded AI assistant (Claude): retrieves only published articles, cites them, drops answers that cite nothing
Postgres full-text search (tsvector + GIN) with ranking, stemming, phrases and highlighted snippets
Append-only audit log written in the same transaction as each change, with filters and CSV export
Role-based access (Requester / Agent / Admin), 370+ backend and frontend tests on real Postgres in CI

Data Engineering

liftpipe

Strength-Training Data Pipeline & Analytics

An end-to-end, free-to-run data pipeline: it ingests Hevy workout exports and Apple Health data, models them with dbt on DuckDB, orchestrates everything as one Dagster asset graph, and serves a static dashboard that queries the marts in the browser with DuckDB-WASM. Visitors can upload their own Hevy CSV and see their own dashboard in seconds.

Layered dbt models (raw → staging → intermediate → marts) with 75 data tests and unit tests
One Dagster lineage graph from file to dashboard — every dbt test becomes an asset check
Idempotent, incremental loads keyed on natural keys and file hashes
Streaming Apple Health XML parser: 27 MB memory on a 109 MB export vs 1 GB for a full parse
Validation at the edge with Pydantic and Pandera before anything is persisted
FastAPI upload API on Railway reuses the batch pipeline; container smoke-tested in CI

Guess the Music

Real-Time Party Music Quiz

Multiplayer music-guessing game for game nights: the TV shows the video, everyone buzzes in from their own phone, and the host runs the round from a control panel. Built with Node, Express and Socket.IO, with English/Farsi (RTL) support and a set of optional game modes. Built with Claude Code; I directed the design, played it with friends and family, and made the product and architecture decisions.
