I'm a Python developer and AI engineer with 10+ years of experience, running a 80-person agency (Go Wombat) with offices in Valencia, Tallinn, and Ukraine. Over the last few years my work has shifted heavily into AI. I build production RAG pipelines, LLM-powered products, and autonomous agent systems - not demos or prototypes that fall apart at scale, but things that run in production and get maintained long-term. Recent projects include a RAG-based troubleshooting system for a UK manufacturing client (Innovate UK funded), an AI investment research platform with OpenAI-powered analysis, LLM compliance automation for an AdTech company, and an AI music therapy product used in dementia and autism care. What I work with on the AI side: * Multi-agent systems and AI workflows using LangGraph, OpenAI Agents SDK, Claude Agent SDK, Google ADK, MCP, OpenClaw-based agents, and custom agent frameworks for tool and data integration * Production RAG systems using pgvector, Qdrant, Chroma, hybrid retrieval, reranking, knowledge graph enrichment, and RAGAS-based evaluation pipelines * Agentic automation with tool use, memory/context management, sandboxed execution, human-in-the-loop approvals, and workflow orchestration * LLM fine-tuning and adaptation with LoRA/QLoRA, synthetic datasets, domain-specific evaluation suites, and structured output validation * Working with OpenAI, Anthropic Claude, Gemini, Qwen, DeepSeek, GLM, Mistral, Kimi, and self-hosted open-weight models * LLMOps and AI observability with LangSmith, Langfuse, Opik, tracing, monitoring, alerting, evals, and regression testing * AI governance and EU AI Act readiness, including risk classification, technical documentation, audit trails, and monitoring workflows * Production deployment of AI systems with APIs, Docker, cloud infrastructure, secure integrations, and scalable backend architectures Focus areas: AI copilots, autonomous workflows, RAG platforms, internal knowledge systems, agentic tooling, AI automation, document intelligence, and customer-facing AI products. On the backend side I've been writing Python for a long time - Django, FastAPI, PostgreSQL, MongoDB, Redis, AWS (EC2, S3, Lambda, RDS, Elasticache), Docker, Kubernetes. That foundation matters a lot when you're building AI systems that need to hold up under real load and stay maintainable six months after launch. I've shipped products across healthcare, fintech, logistics, adtech, ecommerce, IoT, and SaaS. The range matters because AI problems look different depending on the domain - a compliance monitoring pipeline for an ad platform has almost nothing in common with a predictive maintenance system for factory equipment, even if both use LLMs under the hood. Because I run an agency, I can pull in the right people when a project grows beyond one person. Designers, mobile devs, data engineers - whoever the work calls for. But I stay personally involved throughout: I'm the one reading your requirements, scoping the work, and staying accountable for what gets delivered. Several of my Upwork clients have been with me for 5+ years. I mention that not as a credential but because it's the clearest signal I have that the working relationship tends to go well. If you want to talk through what you're building, I'm happy to take a look and give you an honest read before any commitment.
