AI & Agentic Systems
Design and delivery of production AI agents using MCP and A2A for tool use and cross-agent interoperability, with multi-step orchestration via LangChain and LangGraph. Integration of LLM models including Claude and OpenAI GPT, as well as RAG pipelines, vector databases and prompt engineering workflows.
Full Stack Development
End-to-end development of large-scale applications across React, Next.js, React Native, TypeScript, Vue, Go, Node.js and Python. Delivery of production-grade platforms in cybersecurity, telehealth and e-commerce, deployed on AWS and GCP.
Backend Engineering & Microservices
Architecture and implementation of high-performance Go microservices with REST APIs using Gorilla/Mux and gRPC services with Protocol Buffers. Data access via PostgreSQL/GORM, asynchronous processing with RabbitMQ, caching with Redis and container orchestration via Kubernetes.
Frontend Development
Building of modern frontend applications using React, Next.js, React Native, Expo, TypeScript, Vue.js, Nuxt.js, TailwindCSS, Chakra UI, Material UI, Redux, Pinia, TanStack Query, SWR, Zod and React Hook Form.
Cloud Infrastructure & DevOps
Deployment and management of cloud infrastructure on AWS and GCP, including Docker, Kubernetes, CI/CD pipelines via GitHub Actions, Prometheus, Sentry, structured logging, Elasticsearch, Google Cloud Storage and Cloudflare.
Database & Messaging Systems
Design and operation of data layers using PostgreSQL, MySQL, Firebase, Supabase, MongoDB, Redis and RabbitMQ, including transaction management, connection pool tuning and keyset pagination for high-performance reads.
Blockchain & Decentralized Systems
Development of a decentralized authentication system on Ethereum using Solidity, combined with a biometric verification layer built on OpenCV, TensorFlow and OCR to bind on-chain identities to real-world credentials.
Technical Leadership & Mentoring
Leadership of a team of 5 engineers at Offensive Security, owning delivery of AI integration initiatives across a large-scale cybersecurity e-learning platform. Mentoring of engineers on AI/ML best practices and prompt engineering.
Payment & Compliance Systems
Implementation of HIPAA-compliant telehealth systems and high-conversion e-commerce platforms. Integration of Stripe subscription billing, customer onboarding workflows and compliance-critical data handling.

Projekthistorie
Delivery of AI-powered features from technical proposal and architecture through production rollout, integrating Claude and OpenAI models. Design and shipment of agentic AI systems including production agents with MCP tool use, agent harnesses, sub-agents and multi-step orchestration with LangChain and LangGraph. Implementation of scalable backend services and APIs including microservice-based architectures, RAG pipelines and third-party integrations. Built and maintained a Go microservice within the platform's large-scale marketplace architecture, exposing REST APIs with Gorilla/Mux and gRPC services with Protocol Buffers. Implemented JWT authentication with role-based access control and PostgreSQL data access via GORM. Used RabbitMQ for asynchronous processing and Redis for caching and pub/sub. Instrumented services with Prometheus and Sentry, deployed via Docker and Kubernetes with CI/CD pipelines in GitHub Actions.
Co-founded and shipped a cross-platform social fitness app built with React Native and Expo where users share workout journeys and compete through gamified challenges. Built substantial parts of both the frontend and backend, along with the supporting infrastructure, powering the app's live activity feeds, push notifications and leaderboards.
Co-founded and co-owned an AI chatbot platform, sharing responsibility for product roadmap, pricing, feature prioritization and customer support for business customers deploying branded conversational agents. Designed RAG pipelines and prompt-engineering workflows, integrating OpenAI GPT and Claude to deliver context-aware, on-brand responses. Ran the commercial operations side including Stripe subscription billing, customer onboarding and ongoing support.
