Most AI projects don't fail because of bad code or bad tools. They fail because of a lack of alignment. I'm Guido, an AI integration and full-stack specialist. I partner with founders and product leaders to design architectures and software that actually drive real business outcomes, serving as a product-level thinker who makes the right architectural calls. My background sits at the intersection of engineering and strategy. I've built 50+ products across HealthTech, SportsTech, FinTech, and Industrial Manufacturing, and the through-line is always the same: the clients who get the best results are the ones who treated me as a partner in the outcome, not a vendor delivering a spec. --- WHERE I SPECIALIZE: ✦ AI & Intelligent Systems: LLMs, RAG pipelines, agentic workflows, NLP, Computer Vision, OpenAI/GPT, LangChain, PyTorch, TensorFlow. I build AI that integrates cleanly into your existing product architecture, not AI for its own sake. ✦ Full-Stack Development: React, React Native, Flutter, iOS, Android, Node.js, Python, PHP. Infrastructure on AWS, GCP, and Digital Ocean. UX/UI. End-to-end builds from architecture through deployment. --- HOW I WORK: 1️⃣ Discovery: I go deep into your business, your users, and your real objectives. Not just the features on your list, but the outcome those features are supposed to achieve. This changes everything downstream. 2️⃣ Strategy & Roadmap: A clear, prioritized plan with defined milestones, deliverables, and budgets. You know what you're getting, when you're getting it, and what it costs. No surprises. 3️⃣ Build & Iterate: Full transparency throughout. Real-time visibility at every stage. No black boxes, no "trust me" moments. 4️⃣ Launch & Support: I don't disappear at deployment. I stay involved to make sure the product performs, scales, and keeps delivering results after it's live. --- RECENT RESULTS: → Built a custom AI-powered data platform for a Healthcare Market Research company. Automated HCP data enrichment and survey workflows, dramatically reducing manual operational overhead and accelerating turnaround times. → Architected and shipped a professional visual reference app for Digital Artists from zero to launch. Streamlined creative workspaces and integrated with Procreate to reach Top 10 Paid App status in the Apple App Store. → Integrated automated testing infrastructure into a Cloud Services codebase. Reverse-engineered existing systems to build backend and UI test suites in Bitbucket CI/CD, completely eliminating manual testing dependencies. → Developed a centralized "Tool Tracker" digital hub for a large-scale Manufacturing corporation. Linked CNC programs with shop floor tools to transform legacy processes into an auditable workflow that drastically optimized production cycles. --- WHO I WORK BEST WITH: I'm a strong fit if: → You're a founder or product leader who needs a technical partner, not a ticket-taker → You have a complex or ambitious idea that's been waiting for the right person to execute it → You've been burned by developers or agencies who delivered code but not outcomes → You move fast, but not at the expense of getting it right I take on a small number of projects at a time, intentionally. Every engagement gets my full attention from architecture to delivery. If you have a complex product roadmap or an ambitious AI integration you need to execute correctly the first time, send me a message. Let's hop on a brief strategy call to talk through your architecture.
