Work Experience

My professional journey and contributions in software engineering

Backend Software Engineer

Ocean Data Integration Initiative

Berlin, Germany

Apr 2022 — Present

Developed multithreaded microservices for an oceanographic data platform using FastAPI, Pydantic, SQLAlchemy, and Pandas, reducing data processing times and research workloads
Implemented REST APIs and integrated poorly documented external data sources, simplifying research data collection by providing access to 1M+ datasets through a single interface
Decomposed a monolithic data integration system into 3 microservices and owned them end-to-end, allowing independent service scaling and improving maintainability
Provisioned GCP infrastructure containing databases and serverless components, and automated deployment using Terraform, GitLab CI/CD, and Docker
Denormalized PostgreSQL database tables and embedded simple foreign tables into JSON array columns, eliminating complex joins and improving the overall data integration performance
Converted OWL ontologies into Neo4j graphs and SPARQL queries into Cypher, accelerating node retrieval and ontology load times, and enhancing the ontology visualization interface
Replaced custom user authorization and authentication with an OAuth2 and OIDC compliant solution using Firebase and Identity Platform, enabling SSO and simplifying user onboarding

A showcase of my technical projects and solutions

Personal Portfolio Website

HTML5 CSS3 JavaScript Responsive Design

Designed and developed this responsive portfolio website from scratch using modern HTML5, CSS3, and JavaScript. The site features a clean, accessible interface with smooth animations, interactive elements, and optimized performance across all devices and screen sizes.

Oceanographic Data Integration Platform

Python FastAPI Pandas GCP Microservices Ontologies

Took part in engineering a platform that integrates, processes, and delivers oceanographic data from multiple sources, enabling researchers to access and analyze large datasets efficiently. The architecture included multiple microservices, each handling specific aspects of data integration.

Teen Driver Monitor

Arduino GPS GSM LCD IoT Hardware

Built a driver monitoring system using Arduino Nano, which detects driving speed with a NEO-6M GPS module, measures alcohol levels with an MQ-3 gas sensor, reports results to guardians via SMS using a GSM SIM900A module, and displays them in real time on an LCD screen.

Education & Learning

My educational background and learning journey

Self-Taught Software Engineer

Continuous Learning & Growth

I'm a self-taught software engineer with a background in chemistry and electronics from high school. My journey began by picking up a Python book in my teen years, which sparked my passion for programming.

I explored the Linux world, from Ubuntu to Gentoo, learning C and writing shell scripts along the way. This hands-on experience with systems and low-level programming provided a solid foundation for my engineering career.

Through determination and continuous learning, I landed my first professional role and have been progressing my skills ever since. I believe in learning by doing and continually expanding my technical knowledge to tackle complex challenges.
