Most MVPs die within a year. Not because the idea was wrong, but because the technical foundation couldn't hold the next stage of growth.
Hi, I'm Melhem. I build SaaS products so that doesn't happen. Founders bring me in when they need one person to take full ownership of the technical side: not just development, not just advice, real responsibility for how the product is built and how it scales.
Recent work includes Orderitu, a multi-sided food delivery marketplace; SubAI, an AI-powered project management SaaS for contractors with revenue dashboards and AI-generated estimates. I've also worked on a ride-hailing and delivery marketplace, among others.
Today the value isn't the tech stack. It's knowing how to structure systems, choose the right tools, and use AI where it actually creates leverage. That applies to how I work too. I use a structured, multi-agent AI development workflow (planning, implementation, and review split across different tools) to move faster without cutting corners on quality, the same discipline I bring to your codebase.
My core stack: Next.js, React, React Native, Node.js, TypeScript, PostgreSQL, Stripe, and the OpenAI API.
What I help with:
✅ SaaS MVP Development
✅ Marketplace & Two-Sided Platform Development
✅ AI Integration (OpenAI/LLM APIs)
✅ Mobile App Development (React Native)
✅ Full-Stack Web Development (Next.js/Node.js)
I stay close to both the code and the product, from first commit to production and beyond.
If you're building something serious and want a technical partner who thinks ahead and delivers, let's talk.

Clients struggle less with Claude Code itself than with everything around it setup and security sign off upfront, reviewing "almost right" output, unpredictable costs, stale context, and config sprawl day to day, and finally inconsistent results across a team with no shared setup, no review capacity, and no way to prove it's working.
I build that infrastructure.
What I Do
I build production AI systems end-to-end with Claude Code and Claude API from frontend to backend to database to AI workflows. Three live SaaS platforms (ypmgsocialzcom, dropbotaicom, lifeownpropertycom) handle real workflows: user engagement, property management, and AI powered automation. Each system is built to scale, logged to monitor costs and errors, and documented so your team can maintain it without me.
What I Solve
You get a Claude system that works consistently across your team, costs you can predict, and code your team understands. No setup surprises. No "almost right" output requiring rewrites. No stale context causing inconsistent results.
My Specialty
Full stack development with Claude Code React/Next.js frontend, Supabase/PostgreSQL backend, AI workflows
AI feature integration lead qualification, document processing, personalized outreach, data enrichment
Production infrastructure error handling, retry logic, cost monitoring, security reviews, handoff documentation
Scaling workflows n8n automation, API integrations, third party connections
Fast shipping scoped systems with clear milestones, daily progress, predictable timelines
Recent Work Patterns
WhatsApp AI agents (lead capture, collections automation), B2B outbound systems (intent signals, prospect qualification), personal AI assistants (email triage, calendar management, reminders), document to workflow systems, multi step automation with failover logic.
Ready to build? Send a proposal describing your workflow or challenge, and I'll scope it with cost estimates and a clear timeline.

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.

I helped multiple clients launch AI-powered products from MVP to production, reducing time-to-market by 30–45% through clear discovery and architecture planning and enabled startups to scale engineering capacity quickly by assembling and managing dedicated teams of 3-20 engineers, without sacrificing code quality or delivery predictability.
Also, while having an experience of delivery for platforms with 100K+ active users, we can ensure stable performance, monitoring, and zero critical downtime at launch.
Improving infrastructure efficiency and cloud cost control (while achieving 20-35% reduction in operational costs through optimized cloud architecture and CI/CD pipelines) is LITSLINK expertise in their software products development.
If you’re looking for a reliable technology partner who can take ownership of complex software initiatives, LITSLINK is built exactly for that.
