If you’ve seen dozens of generic full-stack profiles that look and sound the same (and yet say very little about how they can actually help your business) you’re in the right place. As someone who spent over $190k hiring freelancers on Upwork in my previous life as a tech executive, I know how frustrating it is to hear about them instead of your goals, your constraints, and your risks. I build full-stack applications that solve real business problems, address concrete user pain points (and don’t collapse under their own weight six months later.) I’ve been a founding member of an 8-figure SaaS, lived through its growing pains from early startup to scale-up, and experienced firsthand what separates a developer-for-hire from a true software partner. Whether you’re validating an idea with an MVP, searching for product-market fit, or dealing with complex business logic that spans product, engineering, and operations, I can help you navigate those decisions, and the tradeoffs behind them. Before taking on freelance clients as a full-stack developer, I spent years as a Product Manager and Executive at Ubersuggest and AnswerThePublic. That’s where I learned how real software gets built at scale: shipping under constraints, making deliberate speed vs. quality tradeoffs, and aligning engineering decisions with actual business outcomes, not just theoretical best practices. Today, I work with founders, startups, and growing teams to design, build, and ship production-ready software, from MVPs to scalable platforms, combining: - Hands-on full-stack development - Practical AI & LLM integrations 🤖 - Product thinking and architectural judgment shaped by real-world constraints My focus is not “more code.” It’s better decisions earlier, when they’re still cheap to change. 🧭 How I Work - I start by understanding the business goal, not just the feature list. - I help define what should be built now vs. later, and what in your scope will move you closer to outcomes (or quietly set you back by months.) - I design systems that are simple first, scalable later, so you’re not paying for complexity you don’t yet need. - I stay hands-on in code while maintaining architectural oversight over every meaningful decision. 🔍You’ll always know: - What’s being built - Why it’s being built - What tradeoffs are being made—and which risks we’re intentionally avoiding A Belief That Filters My Clients 🚦 I believe most software projects don’t fail because of bad code. They fail because too many decisions go unchallenged early, when everyone is still trying to “move fast.” If you’re looking for someone who will blindly implement requirements, I’m not a fit. If you want a partner who will: - Push back when something doesn’t make sense - Flag decisions that will limit you later - Help you think through second-order effects before they become expensive Then we’ll work very well together.
