Collaboration in action
Software, Data & AI
Custom engineering for modern teams
End-to-end software, data, and AI services from an experienced full-stack engineer. I help teams build reliable systems, automate workflows, and ship real products.
Full-stack web apps and APIs (e.g. React, Node, SQL, cloud)
Data pipelines, analytics, and integrations
AI agents, automations, and workflow optimization
Whether you’re launching a new product, modernizing a legacy system, or looking to embed AI into your operations, I can support your project from architecture to deployment. You’ll work directly with me (no layers, no handoffs), just practical engineering that moves your roadmap forward.
Advisory & Fractional CTO Support
Guidance for products and teams
I work with founders and leadership teams to make clear, confident technology decisions, from product strategy and system design to adopting AI where it truly adds value.
Technical strategy and product roadmap input
Architecture reviews and modernization planning
AI opportunities, automation, and integration guidance
Whether you’re scaling a product, improving reliability, or exploring how AI fits into your business, I provide practical, high-leverage support without the overhead of a full-time CTO. You’ll get clear recommendations, steady technical direction, and a partner who helps you move forward with confidence.
Custom requests
I’m available for tailored engagements such as keynote talks, executive briefings, and custom workshops.
Every engagement begins with understanding your goals. From there, I design a concept that blends insight, clarity, and practical relevance ensuring your team leaves with ideas they can immediately apply. Whether you’re looking for a thought-provoking presentation or a hands-on strategy session, I’m open to shaping something that fits your vision and audience.
