I'm passionate about all things web. My career has evolved a lot over its 17-year span from web and graphic designer to developer, entrepreneur, co-founder, and board member. Without the BS, here's what (I think) I'm good at: * Webflow development (I'm certified and Digital Crayon is a Premium Partner) * Architecting web-based products from the ground up * Translating business requirements into products. * Solution architecture (automation, simplifying complex processes and integrations) * I'm also a bit of a Figma wizard (yes developers can love Figma too). * Communication - Regular, clear comms makes or breaks a project, I rate it my #1 most important skill

I help founders ship reliably - full-stack product delivery with AI/ML where it actually makes sense (not just because it's trendy). I'm also a 2x founder with successful exits who ships keeping end-users in mind, because angry users don't care how clean your code is. I know the pressure to move fast, de-risk scope, and ship without drama. My stack is React/Next on the frontend, Node/Python on the backend, AI integrations (Claude, OpenAI, RAG systems that don't hallucinate your revenue numbers), plus WordPress & Shopify when you need marketing velocity, and Flutter when mobile belongs in the plan. I've contributed to teams at Microsoft and Lenovo and shipped for fast-moving startups like Owner .com (raised $100m), GatewayX ($20m/y rev), Shortimize, and more. Most clients come to me mid-sprint with a blocker: failing builds, UI bugs that only happen on Safari, slow endpoints torturing your users, AI integrations confidently making stuff up, or tests that passed locally but explode in production. My playbook starts with a 48-hour triage: reproduce the issue, isolate the root cause, ship a safe fix, and record a short Loom so you can see exactly what changed (no "trust me, it's fixed" energy here). From there, we run small, shippable milestones - acceptance criteria, feature flags, tests, and CI - so progress is visible and reversible when things inevitably get weird. What you can expect working with me: clear scopes, realistic estimates (I won't tell you 3 days when it's actually 3 weeks), weekly demos, and zero surprises on budget. If speed is critical, I can bring a vetted teammate to parallelize without adding management overhead or Slack chaos. Tooling I live in: React/Next.js, Node.js/Express, Python/Django, Claude/OpenAI APIs, Core ML/AI, PostgreSQL/MySQL, REST/GraphQL, AWS/Docker, CI/CD, Flutter etc. Got a project? Let's talk! Tech and tools: Javascript, React, Node.js, Python, OpenAI, Data, WordPress, Shopify, Flutter, Web App, Mobile App, Front-end, Back-end, AWS, Google, eCommerce, SaaS
