I'm an AI-Native CTO with hands-on experience across the full product stack. Software, hardware, and everything in between. I build with AI woven into the process end to end, which compresses timelines and lets a lean team ship like a much larger one. On the software side, I've shipped web applications, iOS and desktop apps, games, and streaming channels for Apple TV and Roku. On the hardware side, I've taken products from schematic to market: designing custom PCBs, resolving supply chain challenges, and building embedded systems around platforms like ESP32 and Nvidia Jetson. I've worked across software engineering, mechanical engineering, and mechatronics; which means I can lead your team and own the architecture, while you focus on the vision.

As a software developer, I aim to provide clear, accurate, and insightful support across a range of technical topics. Here’s what you can expect from me: Technical Knowledge: I'm well-versed in various programming languages JavaScript, Python, Java, frameworks (Springboot, React, Angular, Laravel), databases (MySQL, MongoDB), cloud services (AWS, Azure), and software development methodologies (Agile, DevOps). Whether you're working on full-stack, mobile, or web development projects, I can assist with best practices, debugging, architectural decisions, and optimization techniques. Problem-Solving Support: I can help troubleshoot code issues, suggest improvements, and offer strategies for writing clean, scalable code. If you’re stuck on an algorithm or need guidance on efficient design patterns, I can walk you through potential solutions. Project Guidance: Whether you’re starting from scratch or maintaining a legacy system, I can help with system architecture, API design, testing frameworks, CI/CD pipelines, and deployment strategies. I can guide you through platform-specific concerns, like deploying to cloud infrastructure or setting up containerized environments. Productivity Enhancements: I’m familiar with various development tools (IDEs, version control systems like Git, containerization with Docker, etc.) and can help you streamline workflows. I can offer suggestions for task management, debugging tools, performance monitoring, and versioning strategies. Documentation and Best Practices: Writing good documentation, following coding standards, and maintaining clean, understandable code are crucial for any project. I can provide templates, advice on structuring documentation, and insights into code commenting, all following industry best practices. Collaboration: I’m accustomed to helping developers of all levels, whether solo developers or teams. I can support collaborative development workflows (e.g., GitFlow), assist with peer code reviews, and facilitate smooth communication between backend, frontend, and design teams.

As a senior Flutter developer with 8 years of experience in mobile app development, I possess a deep understanding of the Flutter framework and have a proven track record of delivering high-quality applications. With expertise in cross-platform development and UI/UX design, I excel at creating user-centric and visually appealing interfaces. I am skilled in performance optimization techniques to ensure smooth and efficient app experiences. Additionally, I am a collaborative team player who thrives in cross-functional environments.

I help non-technical founders stop guessing about engineering and start shipping. Most early-stage B2B SaaS startups don’t need a full-time CTO. They need someone who’s built and led engineering teams at companies like Kayak, Toptal, and Huma - and can bring that experience to their startup at a fraction of the cost. That’s what I do through Solidmatics. I’ve spent 20+ years moving between startups and scale-ups across SaaS, healthtech, marketplaces, and e-commerce. The pattern is usually the same: inherited a mess, built the right team, fixed the architecture, shipped the product. Whether that meant taking over from agency developers and rebuilding the entire SDLC, leading 40 engineers on multi-million euro clinical software, or opening a new office from scratch and securing €800K+ in R&D grants. I still code. I’ve been writing software since I was 13, and I keep my hands dirty - React, TypeScript, Java, PHP, Python, AWS, the works. That means when I review your architecture or interview your engineering candidates, I know what I’m looking at. I work with a small partner network of senior architects and DevOps specialists, so clients get a full technical leadership layer without full-time overhead. If you’re a founder trying to figure out whether to hire a CTO, rebuild your platform, or just need someone senior to tell you what’s actually going on in your codebase - let’s talk.
