A Finnish proptech platform where an XGBoost model trained on historical apartment transactions turns an address into an instant valuation — and a valuation into a commission-based sale mandate. I own the model, the warehouse, the scrapers that feed it, the realtor and admin portals, and the WebSocket dashboards on top. Retrained and re-validated every three to four months against newly ingested sales.

I build the things other people got stuck on.
Taught myself to code at fifteen, starting with cyber-security and the parts of a computer nobody looks at. Seven years on, that's still the job.

I work best at the seams: where a model meets a database, where a scraper meets a business that bills on its output, where an undocumented legacy system meets a deadline. I've owned an entire technical estate alone — web app, realtor portal, admin platform, warehouse, scrapers — and I've dropped into distributed teams on a daily ticket cadence without friction.
Nothing about that came from a curriculum. It came from wanting to know how the machine works, one layer further down, and then one more.
“Hand me the problem nobody else could crack. However difficult, it gets built.”✳

Active users on platforms I've scaled
The replacement for the spreadsheet every QA team secretly still runs on: suites, execution runs and results in one platform, with AI-generated test cases. I built the administration portal end to end — tenants, users, audit logging — and shipped Bring Your Own Storage so customers can point the product at their own back-end.
Registering a chemical means transcribing toxicology studies into IUCLID by hand, for days. I built the RAG pipeline that ends that: study PDFs ingested into a Weaviate vector database, LLM retrieval populating structured IUCLID records directly. Shipped publicly as chemassist.ai.
A LinkedIn-shaped network built from the back end out: profiles, connections, feeds, posts, comments and reactions, with privacy controls, background jobs for notifications and analytics, and feed generation tuned for social-interaction volumes that punish naive queries.
Back-end APIs and business logic with server-side processing and layered caching, with endpoints designed around SEO-driven content delivery and structured data consumption — built in close contact with the front-end team rather than thrown over a wall.

Blok.ai
Lead Developer — Sole Engineer
- Sole engineer for the company's entire technical estate — customer web app, realtor portal, admin platform, data warehouse and scraping infrastructure — across a large multi-repository codebase.
- Took over a completely undocumented legacy system after the previous engineering team was dissolved; reverse-engineered the architecture and restored a working delivery pipeline for features and fixes.
- Own the XGBoost apartment price-prediction model end to end, retraining and re-validating it every three to four months against newly ingested Finnish sales data.
- Build and maintain the automated scrapers and ETL processes feeding sold-property data into the warehouse, and act as the single technical point of contact for a commission-based business.
- Deliver real-time dashboards over WebSocket, with Redis caching and query optimisation keeping the platform responsive at scale.

Software Engineer — Contract
- Shipped features and defect fixes on a SaaS test-management platform replacing spreadsheet-based test-case management for QA teams.
- Built the administration portal end to end, covering tenant and user management.
- Integrated AI services for automated test-case generation and validation, and implemented Bring Your Own Storage so customers can connect their own storage back-ends.
- Implemented data encoding/decoding handling, authentication and audit logging for enterprise QA teams on a daily ticket cadence inside a distributed team.
SilverBrain.ai
Full-Stack & AI Engineer — Contract
- Built IUCLID Assist — live as chemassist.ai — automating regulatory data entry into the IUCLID chemical-safety database used for chemical registration.
- Designed and implemented the retrieval-augmented generation pipeline: toxicology study PDFs into a Weaviate vector database, LLM retrieval populating structured IUCLID records.
- Designed scalable REST APIs for complex domain logic, data validation and visualisation requirements.
- Contributed to a second product initiative (Nexus), discontinued for competitive market reasons.

Early-stage start-up
Software Engineer
- Built phishAnt — a Python/Tkinter desktop application and companion Chrome extension classifying URLs as phishing or legitimate with a machine-learning model.
- Developed an automated image-enhancement tool integrating the PerfectlyClear engine, and contributed to an in-house hospital management system.
Grouped the way I actually think about them, not as a wall of logos. Depth is concentrated in channels 00 to 02; the rest is working fluency, earned by shipping with it.
