Frank Hampus Weslien

Anyone can create stuff. I do.

I have practical experience in every step of application development. Everything from coming up with the initial idea, creating UI mockups, logo design, talking to users, frontend, backend, and infra. Programming is a big passion of mine. For example, I’ve built a trustless asset exchange service on the Cardano blockchain and more recently a parser combinator library in Typescript. I always take the opportunity to share my learnings in TechTalks here at GESHDO. Allowing both me and my colleagues to grow.

  • [2016 - 2021] Lund University
    Master of Science in Engineering, ComputerScience and Engineering

    Heavy focus on the fundamentals of computer science and software engineering. For my specialization, I selected courses in machine learning, AI, and mathematics.

    Our thesis explored how to reduce the rate of false positive alarms in static analysis tools. We implemented a prototype by extending JavaDL, a custom programming language for static analysis, to use machine learning to find false positives.
