70% of Founders still Burn months & Half their runway building a SaaS the WRONG WAY. I help founders go from idea to a live, Revenue-Ready SaaS product. Implementing an AI-assisted development system that compresses build time without cutting corners on architecture. I’ve worked directly with SaaS founders for the past 8 years. And built Exonix along the way, where we Engineer for What Actually Matters. In 4+ years, we've shipped 30+ SaaS products and 15+ AI-powered apps to real, paying users. Here’s one of the statistics of RECENTLY SHIPPED app: ➞ 469+ Users | 5 ⭐⭐⭐⭐⭐ Reviews | 1000+ Downloads ------------------------------------------------------------- WHAT MAKES ME STAND OUT What makes me stand out is our Clarity-First approach. This helps us differentiate ourselves from a Savvy who does not understand What To Build and What Not To. I implement a data-driven strategy from day one for your product. This helps you save time, build on a budget, and optimize for PAYING USERS. Where most of the SaaS founders just develop, I help you build for success. ------------------------------------------------------------- WHAT I BUILD FOR FOUNDERS I build SaaS platforms, AI-native products, and mobile apps (iOS/Android, on App Store and Play Store) using React, Next.js, Node.js, PostgreSQL, and AWS, plus GPT-4o, LangChain, and vector databases (Pinecone) when the product calls for AI. We align Stack Decisions to your growth stage, not to pad a resume. A pre-seed MVP and a SaaS scaling to 50k users need different foundations, and I'll tell you which one you actually need. ------------------------------------------------------------- WHY A SENIOR DEVELOPER ISN’T ALIGNED WITH YOU What I bring that a senior freelance developer typically can't: I've built this team from the ground up, and I've watched founders lose their runway to one specific mistake: choosing a stack or scope that looks impressive on day one but creates 6+ months of technical debt by year two. My Job is to PREVENT that! I scope for validation first, polish for user-readiness second, and only then architect for scale: in that order, never reversed. If you're a non-technical SaaS founder, I'm your technical co-pilot: making the architecture, team, and build-vs-buy decisions, not just writing the code. MY 8+ YEAR TRACK RECORD -Launched 30+ SaaS products and 15+ AI/Generative AI applications over the last 4 years, from concept to paying customers -Grew Exonix from a solo freelance practice into a 50+ person team — now holding Upwork's Expert-Vetted badge, both individually and as an agency -Directly worked on or managed 200+ projects for founders and enterprises across the US, UK, Australia, UAE, Saudi Arabia, and Germany -AWS Certified Cloud Specialist, deploying infrastructure that scales without inflating your burn rate I work best with founders who have a real problem to solve and want technical direction, not just a coder taking orders. If you can tell me your stage, your idea, and what's actually blocking you, I'll tell you honestly whether we're a fit — and if a 4-6 week AI-assisted build is realistic for what you're trying to launch. Message me and let's find out.
