Denis S.

I'm an AI Product Engineer with a focus on helping startups and businesses leverage AI and adapt to the modern software industry, which is now more accessible than ever. That includes full-stack development, AI automation, AI integration, prototyping, custom development, and, of course, taking over what you've already built and turning it into a production-grade solution.

AI Prototyping: building fast, working proof-of-concepts to validate ideas 3. AI Hardening: taking over existing solutions and bringing them into production 4. Full-Stack Development: end-to-end product development, from frontend to backend 🌠 My background is in custom software development, and I spent a while working as a hands-on engineer. I was lucky enough to spend my entire career working with fast-growing, large-scale, and enterprise clients, representing an outsourcing vendor. 🌌 Apart from development activities, I was engaged in many others: interviewing engineers, participating in pre-sales, training programs, leading and driving development processes, and much more. I was always a company guy and was interested in and open to everything. 👴🏻 That’s where I matured as an engineer. I learned a lot along the way, saw how painful the software development process could be, and understood the pros and cons of different organizations, including where Fortune 100 companies struggle. 📺 I’m a professional engineer focused on delivering business outcomes for you — not a part-time freelancer juggling Upwork with a full-time job or doing it for extra income. I'm working with all types of clients and budgets. ✅ 99% Job Success Score; 100 + projects delivered — from idea to production-ready software 🛡 Expert-Vetted — interviewed and approved by the Upwork team 🚀 Fastest-Growing Upwork Profile Globally — $4M+ earned across multiple profiles since 2022 🌍 Most Recognized & Viewed Upwork Profile Worldwide 💰 Scaled 5 Upwork Profiles to $300K+ revenue each with strong inbound leads 🏢 Delivered Projects for Fortune 100 & Inc. 5000 Companies and UAE government 🧠 Led Pre-Sales, Estimations, Code Reviews & Tech Interviews for top-tier clients 💻 Even if we don’t end up working together, I’ll help you identify risks and guide you on how to make the product happen — because in the end, it’s all about mindset, not just coding skills. 💡 Answering a question how am I different in this competitive AI industry — the answer is simple: mindset. You can learn endless frameworks, libraries, languages — alright, cool, but mindset and deep understanding of this world outside and inside the industry is what really makes a difference.
