Description

About me

I am a computer science graduate and full-stack developer with a focus on the FinTech sector. In addition to technical development, I bring expertise as a certified IHK financial investment professional (according to § 34f GewO). This combination enables me to translate financial requirements into software.

Technical Focus

Languages & Frameworks: Python (FastAPI) and TypeScript.
Frontend: Implementation of modern interfaces with Next.js.
Infrastructure & Cloud: Secure handling of AWS (Lambda, S3, EC2, SQS, RDS, DynamoDB, Cognito) as well as Supabase and Docker.
Architecture: Development of full-stack monoliths for lean applications or event-driven microservices (Clean Code) for complex backend systems.

Experience

My focus is on collaborating with startups, particularly in the FinTech sector. I have accompanied lead generation processes for brokers multiple times and integrated marketing APIs (including Meta, TikTok, YouTube).

Working Method

I work close to the product and see myself as the interface between technical implementation and the product owner. By using Agentic Engineering (AI-assisted development), I can very efficiently familiarize myself with new tech stacks.

Why me?

As a developer with an IHK degree in finance, I understand the logic behind financial products. This saves time in requirements analysis and minimizes development errors at the interface between business and IT.
