I design, build, test and deploy complete software platforms—from data architecture and backend APIs to AI integration, user interfaces, cloud deployment and automated quality assurance. My strongest technologies are Python, Django and PostgreSQL, supported by extensive JavaScript/TypeScript experience with MERN and MEAN applications. As an EU citizen, I offer convenient working-hour overlap for European and US clients. ## What I Build • AI & Generative AI: LLM applications, RAG systems, AI agents, chatbots, semantic search, structured outputs, function/tool calling, prompt engineering, model integration and evaluation. • Data Engineering: ETL/ELT pipelines, data ingestion, transformation and validation, database design, query optimization, time-series processing, IoT sensor integration and data-quality automation. • Full-Stack Systems: scalable APIs, responsive web applications, authentication, third-party integrations, background processing and real-time communication using WebSockets and SSE. • DevOps & Cloud: containerized deployment, Linux environments, CI/CD workflows, asynchronous services, production configuration and deployment automation. • QA Automation: API, integration, regression and end-to-end testing, validation scripts, test-data workflows and automated quality gates. ## Technical Stack AI: OpenAI API, Anthropic, Gemini, Hugging Face, LangChain, LlamaIndex, PyTorch, TensorFlow and scikit-learn. Vector infrastructure: FAISS, Chroma, Pinecone and pgvector. Backend & frontend: Python, Django, Django REST Framework, Falcon, Node.js, Express, React, Angular, JavaScript, TypeScript, C#/.NET and Java. Data: PostgreSQL, MongoDB, SQL Server, Redis, SQL, pandas, NumPy and SciPy. DevOps & real-time: Docker, Docker Compose, AWS S3, Heroku, Linux, Gunicorn, Celery, Redis Pub/Sub, Django Channels, WebSockets, SSE and cron. Testing: Pytest, Jest and Playwright. Integrations: Stripe, Firebase Cloud Messaging, Expo Push, OpenAI and other LLM APIs, Met.no, Meteostat and custom third-party services. ## What I Bring I take ownership from initial requirements through production deployment. I have independently built systems from zero, coordinated Android and iOS developers on API consistency, integrated complex external services and mentored junior engineers. My combined experience in backend engineering, data, AI and infrastructure enables me to solve problems across the entire platform—not just one isolated layer. I prioritize scalability, security, maintainability, clear communication and documentation, delivering systems that teams can confidently operate and extend. less -
