I build production AI systems and the software they run on. 15 years in .NET and the Microsoft stack, with the last two focused on shipping real AI: Claude-powered agents, MCP servers, RAG pipelines and workflow automation that businesses depend on daily. AI AND LLM ENGINEERING - Production multi-agent Claude systems: intent routing, structured outputs, human approval gates, cost tracking, audit logging - MCP servers exposing business operations as controlled, callable tools with real authorization boundaries - RAG and vector search (Postgres/pgvector) with strict citation discipline, built to say "not found" rather than invent - OCR and document extraction pipelines (Mistral, Claude) turning messy PDFs into structured data - AI customer support and enquiry bots answering from a knowledge base, with escalation to humans - Browser and workflow automation (Skyvern, Playwright), Twilio AI calling, email agents via Microsoft Graph - AI-first development with Claude Code as a daily driver, with the discipline to review and verify everything that ships .NET AND ARCHITECTURE - .NET Framework through .NET 10: ASP.NET Core, Blazor, MVC, Web API, Minimal APIs, EF Core - Multi-tenant SaaS architecture, event sourcing, row-level security, immutable audit trails. Sole architect on an FCA-regulated platform that ran seven years in production - Cloud: Azure (Functions, Key Vault, Service Bus, Event Grid) and GCP (Cloud Run, Cloud SQL, Pub/Sub, Secret Manager) - Legacy modernization: Web Forms, Classic ASP, VB.NET and .NET Framework carried to modern .NET, using strangler-fig so systems stay live throughout FRONTEND, DESKTOP AND MOBILE - Angular, React, TypeScript, Next.js, Blazor, Tailwind, D3 - WPF, WinForms, Windows services and workers, UDP/TCP servers - MAUI and Flutter mobile apps, published Chrome extensions with 200,000+ users and Featured badges on the Chrome Web Store INTEGRATIONS - Stripe, Microsoft Graph, Shopify, Xero, QuickBooks, HubSpot, Klaviyo, eBay, Epic and Cerner FHIR, HAPI FHIR, and a long list of others. Bridging messy third-party systems behind clean internal contracts is a large part of what I do. I work solo, take projects end to end, and prefer long-term engagements. Most of mine have run multi-year. Available immediately, fully remote, EET (UTC+2) with full UK and European overlap. Also partial overlap with US EST hours. Portfolio: codebydaniel.net

Full-Stack Web Developer Hi, I'm Elvis. I'm a Full-Stack Web Developer with 9 years of experience building all kinds of Web, Mobile, and Desktop applications. I've worked with clients from many different industries, helping them turn their ideas into real, functional products. Most of my work is around modern web technologies — HTML, CSS/SCSS, JavaScript/TypeScript, Python, and .NET C#. I enjoy building clean, user-friendly frontends and solid, reliable backends. Along the way, I've integrated lots of third-party services like PayPal, Stripe, WhatsApp, Telegram, Google APIs, and more. I'm comfortable working with databases such as SQL, MySQL, PostgreSQL, and MongoDB. I've also deployed projects to AWS, GCP, Vercel, Hostinger, and other hosting platforms. Beyond traditional development, I work on AI code evaluation — creating rigorous coding tasks, writing test suites, reviewing AI-generated code for correctness, and performing detailed QA analysis. This involves deep code review across multiple languages, writing technical specifications, and verifying everything through Docker testing pipelines. If you already have UI/UX designs, I can bring them to life using React/Redux, Angular, Material-UI, Nebular, Bootstrap, and similar tools. Other tools and skills I use regularly: Git (advanced workflows — patches, diffs, rebasing, multi-repo work) Docker for testing and deployment Technical writing — specs, QA reports, task descriptions A few things about how I work: I follow modern standards and good development practices I like writing clean, organized, readable code I'm persistent and always learning I'm honest about my hours and prefer long-term collaborations Feel free to check out my portfolio and reviews. If you think I might be a good fit for your project, I'd be happy to talk.
