Software Developer / Backend & Data Engineering
I build tools that solve real problems. At Amazon I turned a 15-minute manual workflow into a one-click browser extension used daily by operations teams.
Fig. 01, M.A.Software developer based in Hamburg. I build tools that solve real problems. At Amazon, I built a browser extension that turned a 15-minute copy-paste workflow into a one-click operation. My team uses it every day to coordinate with delivery partners across the Hamburg network.
I specialise in backend development and data engineering: Python ETL pipelines, Java and Spring Boot APIs, cloud infrastructure on AWS, and LangChain-based GenAI integrations. I graduated in October 2025 from the Free University of Bozen-Bolzano with a B.Sc. in Computer Science.
I grew up in Ghana, went to high school in Italy, and now work in Germany. Picking up languages and adapting to new environments is kind of my thing. If I see people doing the same annoying task over and over, I will usually try to automate it.

FeaturedA GenAI platform where founders record their pitch and get instant, structured feedback on problem-solution fit, business model, team presentation, and overall quality. GPT-4 powers evaluation, with real-time data sync via Convex.
FeaturedOperations teams were manually copying delivery-partner data, processing it in Excel, then messaging each partner, 15 minutes per cycle. This browser extension automates the whole workflow in one click, and is now used daily by the Hamburg operations team.
FeaturedAn ETL pipeline that extracts structured data from unstructured job postings using a LangChain RAG pipeline and GPT-4. Pydantic schemas validate every record before storage in SQLite. FastAPI exposes the extracted data via REST endpoints with auto-generated OpenAPI docs.
A production-style ETL pipeline orchestrated with Apache Airflow that extracts hourly weather data from the Open-Meteo API, transforms it with Pandas, and loads it into PostgreSQL. Containerised with Docker Compose, with retry logic, email alerts, and idempotent loads to ensure data consistency.
A production-ready authentication microservice built in Kotlin with Spring Boot. Implements JWT, OAuth2, and role-based access control. Fraud detection features include rate limiting, IP blocking, suspicious login detection, and account lockout. Full test coverage with JUnit and Mockito.
A Java application that pulls and processes 10,000+ tourism records from an API. Traced a crash on large datasets to the HTTP library, switched libraries, and tuned JVM memory to handle the full dataset.
A compiler that turns C code into executable programs, lexer in Flex, parser in Bison, plus type checking that catches errors like adding strings to numbers. Supports variables, control flow, and line-numbered diagnostics.
