If you need a full stack developer and engineer who can deliver without rework, I can help. ✅ 6,000+ hours worked on real client projects ✅ 15+ MVPs delivered, from idea to working product, ready to scale ✅ 100% Job Success Score ✅ Top 3% of talent on Upwork Beyond building from the ground up, I specialize in jumping into existing codebases to stabilize and scale them. Whether you are dealing with technical debt, legacy systems, or performance bottlenecks, I provide deep-dive audits, refactoring, and feature optimization to ensure your current product is production-ready and built to handle increasing user loads. I’m a senior full stack engineer working with React, Node.js, Python, and PHP. In my work, I focus on building real products end-to-end, from idea to production, with full ownership and predictable delivery. I work primarily as a full stack engineer specializing in React and Node, building modern web applications using React, Next.js, and Node.js. On the backend, I also work as a full stack engineer with Python and PHP, choosing the right stack based on the product and scaling needs. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Skills & Services ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ Backend: Node.js, Python, PHP, Laravel, Express ▸ Frontend: React, Next.js, JavaScript ▸ Databases: PostgreSQL, MySQL, MongoDB ▸ APIs: REST APIs, third-party integrations ▸ DevOps: AWS, Docker, CI/CD As a full stack engineer (Node.js/Python), I build robust APIs, business logic, and complex integrations. As a full stack engineer (React/Next.js), I build fast, clean, and scalable interfaces. I often lead full stack engineer React Node projects, connecting frontend and backend into a single reliable system. I also take on PHP projects when stability and speed of delivery are critical. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ How I Work as a Full Stack Engineer ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ As an experienced full stack developer, I focus on: – Clean and scalable architecture – Fast frontend with React and Next.js – Stable backend with Node.js, Python, or PHP – Production-ready delivery I can join as a full stack engineer or take a broader role with total ownership over architecture and execution. Beyond standard engineering, I bring the comprehensive mindset of a senior web developer to modernizing legacy systems. For instance, if your platform was originally built by a WordPress developer and is now struggling to scale, I specialize in migrating those monolithic systems into custom, high-performance architectures. If your business has outgrown what a standard WordPress developer can provide, I can rebuild your platform from scratch. As a React developer, I transform outdated interfaces into blazing-fast web apps. Additionally, while I am not a native mobile app developer, I regularly collaborate with your mobile app developer team by building the robust backend infrastructure and optimized REST/GraphQL APIs they need. Every professional web developer knows that a great frontend depends on a solid backend, so I ensure that your mobile app developer gets seamless, well-documented endpoints, while I focus on the web ecosystem as a dedicated React developer. Ultimately, whether you are transitioning away from a legacy WordPress developer setup, looking for a web developer to build enterprise-grade systems, or need a React developer who knows how to support a mobile app developer, I deliver clean, production-ready code. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Experience ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ SaaS products ▸ Internal tools and dashboards ▸ Travel & Logistic platforms ▸ Fintech platforms ▸ E-commerce systems As a full stack developer React Node, I deliver complete products that are ready for real users and real load. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ If you are looking for a full stack engineer who can take ownership and ship, feel free to reach out.

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.

AI agents, RAG, and automation built into production web and SaaS apps, full-stack, not demos. Recent builds scaled an energy platform to 1.2M+ users and an AI document system across 550+ sites. I'm a senior full-stack and AI engineer (React/Next.js + Python/FastAPI) who makes AI actually connect to your data, your UI, and your users. What I deliver: - AI agents and automation that plan, call tools, and finish multi-step jobs (LangChain, LangGraph, MCP, OpenAI, and Claude APIs), with evaluation and observability built in. - RAG and document intelligence over your data (vector DBs, embeddings), grounded so it answers from your sources, not invented facts. - Voice and conversational AI in production (Retell, Vapi, ElevenLabs). - The full-stack around it: multi-tenant SaaS, FastAPI, Stripe, secure cloud on AWS, Azure, GCP. Proven in production: - Alta (PropTech): AI reads building documents to auto-extract energy data and answer questions across 25+ organizations, 550+ sites, 1.6M+ m2. - OhmConnect (GreenTech): 4.5-year build scaling a consumer energy platform to 1.2M+ signups, $1.8M+ rewards, 370K+ connected devices. - Hero Trainer (HealthTech): cross-platform fitness app with live HealthKit and Google Fit sync on a Django backend. I work as your AI solutions architect with a vetted CodeFulcrum team (Top Rated Plus) behind me, so the right AI gets designed and shipped, not just advised on. Stack: Python, Django, FastAPI, LangChain, LangGraph, MCP, RAG, Vector DBs, OpenAI, Claude, React, Next.js, Node.js, PostgreSQL, AWS. Send your use case, and I'll reply with a short architecture sketch and a realistic scope, no charge.
