Need to ship faster without losing control of quality? I lead a vetted, AI-native team that takes real ownership of your product and starts moving the needle in days, not weeks. I help founders, CTOs, and product owners turn roadmaps into shipped, scalable products. My team works as true partners, not order-takers — we obsess over the user, sweat the details, and make decisions through the lens of your business goals, not just the ticket in front of us. Here's what working with us looks like: thorough testing plans and clear documentation so quality holds as you grow, daily updates that report real progress instead of activity, and tight alignment to your priorities so every sprint moves the product forward. We build for scale from day one, so what we ship today doesn't become tomorrow's bottleneck. We've delivered across the full spectrum: consumer apps with 1M+ downloads like Christian Dating For Free, the marketing site for unicorns like Deepgram, and complex enterprise systems like Arriba Data Systems, a leading California platform for workers' compensation. That range means we're as comfortable with a focused 2–3 week build as we are with ongoing, flexible engagements that run for years. We're as comfortable with a focused 2–3 week build as we are with ongoing, flexible engagements that run for years. We're stack-agnostic across 100+ technologies — whether your product needs TypeScript, Dart, C#, or something else, we bring the right tools and senior engineers to the problem. The constant isn't the language; it's the ownership, accountability, and product thinking we bring to every engagement. You get the speed and flexibility of staff augmentation with the structure, visibility, and ownership of a real delivery partner. Can you share a bit about your product so we can schedule a quick 30-min call to confirm we're a great fit to work together?

Most business software is either too expensive, too rigid, or just doesn’t match how you actually work. I build custom systems that automate processes, reduce manual work, and scale with your business - exactly the way you need. 🚀 Many businesses rely on expensive, off-the-shelf software that doesn’t fit their real processes - or forces them to pay for features they don’t need. I design and build custom systems that: • match your actual workflows instead of forcing you to adapt • automate manual processes, saving time and reducing errors • integrate with your existing tools seamlessly • stay flexible as your business grows What I deliver: • Custom business systems replacing or complementing legacy platforms • Process automation and workflow digitization • CRM/POS integrations and data synchronization • Scalable, maintainable architecture (.NET, React, Angular, MS SQL, MongoDB, Node.js) How I work: I start by understanding your operations and pain points, then design a solution that eliminates inefficiencies and unlocks growth potential - without overpaying for unnecessary complexity. If you’re paying too much for software that doesn’t really fit your business, I can help you build something better.

Is your payment infrastructure costing you customers, revenue, or sleep? I build payment systems that don't just work — they scale, recover automatically, and turn checkout friction into conversion. With 10+ years in FinTech, I've architected payment infrastructure for startups and enterprises alike — processing $20M+ in transactions across 200+ apps globally.

Helped BrainTap double revenue and hit a 99.6% crash-free rate post-integration 2. Cut payment processing overhead by up to 69% for SaaS and subscription businesses 3. Launched 200+ apps with compliant, scalable payment systems across iOS, Android, and web Who I Work With SaaS founders, FinTech startups, marketplace operators, and product teams who need payment infrastructure that's built to last — not patched together.
