🚀 Computer Vision | NLP | AI Engineer | Machine Learning & Deep Learning | AI SaaS & Automation Bringing AI-Powered Innovation to Enterprises I am an AI engineer with over 11 years of experience in developing deep learning solutions, natural language processing, and computer vision. My journey in AI started more than a decade ago, working on advanced projects that helped businesses automate processes, analyze data, and make smarter decisions. Four years ago, I joined Upwork to offer my expertise globally, successfully delivering impactful projects in areas such as: ✅ Text classification and sentiment analysis using advanced NLP models ✅ AI-driven cybersecurity solutions for IoT network traffic analysis ✅ Medical image analysis using CNN-based models for enhanced diagnostics I took the challenge. I optimized the dataset, fine-tuned an Arabic NLP model, and streamlined the preprocessing pipeline. Within days, the classification accuracy improved significantly, and the client was thrilled. Soon, larger companies started noticing my work. Then came a cybersecurity firm struggling with IoT traffic vulnerabilities. Their system was unable to detect threats effectively. I built a CNN-based model that analyzed real-time network traffic, improving threat detection accuracy by 40% while reducing false positives. Another client, a healthcare startup, faced challenges in medical image analysis. I developed a deep learning model using CNNs for ultrasound image quality assessment, ensuring reliable diagnostics. This solution reduced errors and improved medical imaging workflows. One of my most demanding projects involved incremental learning for AI models. The challenge was to update a deep learning model with new data without forgetting previous knowledge. By implementing advanced transfer learning techniques, I ensured the model retained past insights while adapting to new patterns. That $50 project was more than just a small job—it set me on a path to solving complex AI problems and driving impactful innovation. And this? It’s just the beginning. Now, We Build AI Solutions for Enterprises Worldwide Today, I lead a team of AI specialists, delivering state-of-the-art solutions in machine learning, deep learning, NLP, and computer vision.

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.

I build production-ready AI systems (RAG pipelines, LLM applications, and multilingual NLP) that solve real problems, not just demos that break in production. I'm a PhD researcher in AI/ML with 6+ years building NLP, machine translation, and information retrieval systems, with published work in ACM, Elsevier, EACL, and FIRE. That research background means I can handle the hard problems most freelancers can't: cross-lingual retrieval, low-resource and Indic languages, speech-to-speech systems, and LLM pipelines that actually hold up. What I can build for you: ✔ RAG pipelines and LLM-powered applications (LangChain, HuggingFace, PyTorch) ✔ NLP systems: text classification, NER, sentiment analysis, transformers ✔ Multilingual & cross-lingual AI, with deep expertise in Indic languages ✔ Speech-to-text and speech-to-speech AI ✔ Search and information retrieval engines ✔ Custom ML models: supervised, unsupervised, and deep learning ✔ End-to-end AI pipelines, from prototype to deployment I communicate clearly, hit deadlines, and care about code you can actually maintain. If you have an AI/NLP problem you're not sure is even solvable, that's exactly the kind of project I like. Send me a message and let's scope it.
