Senior Engineer with 17+ Years of Experience | Laravel · Vue · React · Next.js · Supabase · Inertia · Mysql · PostGreSQL | SaaS, Multi-tenant, AI & IoT Platforms I've been building web software since before "full-stack" was a job title. Seventeen years later, I'm leading senior engineering teams and guiding startups as a fractional CTO. If you are an early stage startup or a solo founder or an Enterprise, this is how I can help you: ➡️ Building your SaaS & Web Apps — Laravel, Vue.js, React, Next.js, Node.js, REST APIs, PostgreSQL/MySQL ➡️ E-Commerce & Marketplaces — Multi-vendor platforms, custom storefronts, Stripe/PayPal integrations ➡️ Legacy Rescue — Taking over broken Laravel/Vue codebases and making them something you're not embarrassed to show people ➡️ AI & Automation — LLM integrations, GPT-based features, workflow automation ➡️ IoT Platforms — Device networks, real-time pipelines, operational dashboards Some work I'm proud of: - I architected the Indiana First Steps platform for the US government — a HIPAA-compliant early intervention system with multi-agency data sharing and eligibility logic that had to be right, because the people depending on it couldn't afford for it not to be. - I was a Technical CEO for a US utility SaaS company, where I designed the backend infrastructure managing 10,000+ households daily. IoT device networks, real-time data processing, the works. That one taught me a lot about what "scale" actually means versus what people say it means in job posts. - I led frontend architecture for Rebel Walls, a global e-commerce brand that needed cinematic performance across markets. High-traffic, high-stakes, zero tolerance for slow. How I work: I've held CTO, Product Lead, and Scrum Master roles — so I've sat on both sides of the founder-engineer tension enough times to know where it usually goes wrong. My job is to close that gap: give you an honest read on what's feasible, tell you when a scope is going to bite you later, and ship code that the next developer won't curse me for. I also run Kinetik Dynamics, which means if your project suddenly needs to move fast, I have senior engineers I trust who work under my direct oversight. Not outsourced. Not farmed out. I'm still the one responsible. Stack I work in regularly: Laravel · Vue.js · React · Next.js · Python · TypeScript · Tailwind · PostgreSQL · MySQL · Redis · AWS · Docker · REST & GraphQL · Stripe · OpenAI API · Gemini API · Claude API · Supabase If the project matters to you, send me the details. I believe, I can help you out greatly.
