Cloud-Native Development on AWS
Over 5 years of experience building cloud-native systems on AWS, including Lambda, API Gateway, SQS, DynamoDB, and Cognito. Proven track record operating high-scale serverless platforms supporting 10,000+ users and monthly AWS spend exceeding $50k.
Infrastructure as Code with Terraform and AWS CDK
Expertise in codifying 100% of infrastructure using Terraform and AWS CDK, ensuring reproducible environments, least-privilege security, and zero-downtime production migrations across AWS regions.
Python Backend Development
Strong proficiency in Python-based backend development using FastAPI and Django. Experience building and maintaining production Python services, microservices architectures, and ETL pipelines for customer-facing platforms.
Serverless Architecture
Design and implementation of fully decoupled serverless architectures using FastAPI and AWS Lambda, including AI orchestration pipelines with SQS and exponential backoff patterns.
CI/CD and DevOps
Implementation of CI/CD pipelines using GitHub Actions, including custom DynamoDB migration tooling integrated directly into pipelines to ensure schema consistency.
Distributed Systems and Performance Optimization
Redesign of single-threaded processing tasks into parallelized serverless workloads using SQS and Lambda, improving system throughput by 5x.
Observability and Monitoring
Implementation of end-to-end observability using structured JSON logging and distributed correlation IDs to trace requests across decoupled services.
SQL and NoSQL Databases
Experience with PostgreSQL and DynamoDB, including schema design, migrations, and custom migration tooling for production environments.
Docker and Containerization
Use of Docker for containerized application development and deployment within cloud-native and distributed system environments.

Projekthistorie
Architected a multi-tenant real estate analytics platform using a fully decoupled serverless architecture with FastAPI and AWS Lambda. Engineered a resilient AI orchestration pipeline utilizing SQS and exponential backoff patterns. Codified 100% of infrastructure using AWS CDK and Terraform. Implemented end-to-end observability using structured JSON logging and distributed correlation IDs.
Acted as Team Lead for 5 months, coordinating delivery across distributed teams and conducting 60+ technical interviews. Operated high-concurrency AWS environments supporting 10,000+ users and 5,000+ concurrent Lambda executions. Redesigned single-threaded processing tasks into parallelized serverless workloads improving throughput by 5x. Designed and executed zero-downtime production migrations across AWS regions. Spearheaded the development of a microservices-based marketplace and solar analytics platform integrating satellite imagery analysis into automated ROI estimation engines.
Contributed to backend development, infrastructure, and analytical tooling for a real estate investment platform within a startup engineering team. Developed and maintained production Python services and Django applications supporting customer-facing platforms.
