Über mich

I am a Senior Full-Stack Software Engineer based in Hamburg with over 10 years of professional experience in designing, building, and scaling web applications and SaaS platforms.

As Founding Engineer & Technical Lead at Flottando (since 2022), I architected a fleet management SaaS platform from zero — Python/FastAPI backend, React/TypeScript SPA, AWS infrastructure (Lambda, S3, SES, Cognito), and CI/CD pipelines. I delivered 6 major product modules end-to-end and deployed an AI-powered invoice processing pipeline using agentic workflows, AWS Bedrock, and OCR. I also built internal Model Context Protocol (MCP) servers for AI agent integration across the organization.

At Jimdo (2022–2025), I re-architected the core website builder platform and CMS for third-party integrations, designed a Stripe-based payment platform with Terraform-managed infrastructure, and pioneered Jimdo's AI-powered website building experience by integrating GPT-3 — making it the first European website builder to leverage LLMs.

At FREE NOW (formerly mytaxi, 2017–2021), I maintained core microservices powering the ride-hailing platform using Kotlin, Java, and Terraform on AWS, led the technical implementation of 4 internal web tools, and served as interim Product Owner.

I am an active open-source contributor with merged PRs to the Serverless Framework (46k+ stars) and GoReleaser (14k+ stars), and have published my own tools on npm including texterify-mcp and Sheetspeare.

Core technologies: TypeScript, JavaScript, Python, Java, Kotlin, Go | React, Next.js, Vue.js, Angular | FastAPI, Express, Spring, Node.js | PostgreSQL, MongoDB, DynamoDB | AWS (Lambda, S3, SES, SQS, Cognito, CloudFormation), Terraform, Docker | AWS Bedrock, OpenAI, Vercel AI SDK, MCP protocol, Agentic AI workflows.

I hold a Diplôme d'Ingénieur in Computer Engineering from ENICarthage (Tunis), graduating with 17/20.
