I build web applications and backends on AWS

I've been programming professionally since 2013. I join teams as a contractor, and I take on smaller projects, such as company websites, web apps and integrations, on my own. I also work with machine learning and AI.

I have worked in teams building systems for Sky, hayu (NBCUniversal), Wärtsilä, RTS and Bird Control Group. Selected projects

What I do

  • Contract development

    I join your team as a frontend developer, a backend developer, or both. VAT invoices.

  • Websites and web apps

    Company websites and applications in React and Next.js that load fast and are cheap to run.

  • Machine learning and AI

    Machine learning and AI: forecasting, classification, pattern detection, text recognition in images, speech transcription, LLM agents.

  • Integrations and automation

    I connect systems through APIs, automate repetitive work and build data workflows on AWS.

How we work together

  1. Conversation

    You tell me what you need and I ask about the details. We agree on what to build and how we'll work.

  2. Estimate

    I give you an hourly rate or a fixed price for the scope. I issue VAT invoices.

  3. Work

    I work in short stages and regularly show what already works, so anything that needs changing comes up early.

  4. Launch

    I launch the finished application on your infrastructure or in the cloud, and I can stay on for further development.

About me

My name is Łukasz Wątor, and ThorSoft is the brand of the company I've run since 2021.

I write frontends in TypeScript and React (company websites in Next.js) and backends in Node.js and Python, most often on AWS. I have worked in teams building systems for, among others, Sky (television and streaming), hayu (NBCUniversal's streaming service), Wärtsilä (marine and energy technology), RTS (intercom systems for broadcast production) and Bird Control Group (IoT devices).

I built my first neural networks at university and have worked on my own models regularly since 2024, mainly on time series. The company is based in Gdańsk, Poland.
