Taking custom projects from blank page to reliable product, without unnecessary complexity. If your project needs: 🖥️ A custom full-stack web app or an internal tool 🦿 An automated workflow - AI-powered or not 🦾 AI integration for your existing project 🤖 Custom AI agents for personal or team needs 🎳 Multi-agent applications that operate autonomously or collaborate with humans Working solo, I have designed, built, and shipped 60+ built-to-last apps, which requires way more than pure development. I also architected a complete B2B AI SaaS in a competitive space, getting first clients in 3 months by connecting with ICPs personally. These strong hands-on experiences give me the outcome-based intuition to know what’s truly important when balancing your business requirements with the technical side. I enjoy turning chaos into deterministic systems. Complex solutions for complex ideas are not always the best. I offer the simplest (not basic) and best practice solutions that can scale with your business. I do this after fully understanding your needs, supported by experience-driven design decisions. I follow these principles in my work: 🦾 Scalable: I make things that can grow as your business grows. 👍🏻 Understandable: Even though the solution is technical, I will prepare a high-level diagram that shows you the big picture and the whole flow. 📦 Reusable: I value modularity in order to save time in your various projects with similar functionalities. 💼 Industry Standards: I rely on proven engineering practices at the project's core. ✈️ Sustainability: I design solutions with minimal maintenance needs from the start, and I continue to support the long-term sustainability of my work. My top talents: ✅ AI Solution Design & Development (Leveraging the latest trends and technologies) ✅ Full Stack Development (End-to-end SaaS, Web Apps) ✅ Backend Development (API, Automation, Scripting) My Approach: I dive straight into your business goals. I push back on early assumptions to find out what is actually needed - and what isn't. Once the problem is clear, I move fast. I build clean, robust systems with strict principles from day one. I keep dependencies to a minimum, completely separate AI from standard logic, and keep things simple so nothing is over-scoped. At every milestone, I make sure the technical strategy directly serves your business goals. I guide the process and keep you completely updated along the way. Bring your messiest problem, and I'll give you a brutally honest assessment. If we're a match, great. If not, you walk away with absolute clarity. We'll do this efficiently, saving you time and energy. 📍Recent Work - AI Systems, Automation & Full-Stack SaaS: 📑 Source content → branded, template-perfect PDFs at scale (content business): Internal tool that takes raw source material as input and outputs reformatted, paraphrased, on-brand PDF documents following a strict custom template - with full page-by-page editing.
