Your AI product needs to go from demo → launch-ready. Your pipeline needs a system, not random posts. Your workflows are leaking revenue through manual gaps.

I'll tell you: Which sprint fits best What is slowing growth The fastest path to results Let's build something that ships, scales, and generates revenue.

I'm a former CTO (venture-backed PropTech, led 20+ engineers) who builds MVPs that are ready for real users from day one. Most MVPs fail before launch. Not because the idea is bad, but because what gets built isn't production-ready. No monitoring, no standards, no security. A prototype dressed up as a product. What you get: - Full technical ownership: frontend, backend, APIs, database, infrastructure, deployment - Production baseline on every project: auth, payments, monitoring, error handling, CI/CD, security, documentation - AI-accelerated development with CTO-level standards: startup speed, enterprise foundations - One person, no handoffs ⚠️ Vibe-coded your way to a working prototype? I take it to production. Recent work: PropTech SaaS serving 100+ real estate agencies as co-founder/CTO. AI website generator with 100+ paying restaurants. eSignature platform on government-backed trust infrastructure. Core stack: TypeScript, Next.js, Node.js, Python, PostgreSQL, AI/LLM integrations. Shipped on AWS, Vercel, Supabase, bare metal. How I work: fixed price, clear scope, clear milestones. You know what you're getting, what it costs, and when it ships. Send me your idea.

Most clients reach out after facing slow React apps, unstable APIs, security gaps, unscalable MVPs, or manual workflows that waste time and money. I fix these problems by designing clean architectures, high-performance systems, and AI automations that actually execute tasks instead of just responding. I’m a Senior Full-Stack MERN / MEAN Developer with strong AI Automation expertise, helping startups and businesses build scalable web applications and intelligent AI-driven systems that perform reliably in real-world environments. I’ve worked across SaaS, FinTech, E-commerce, Logistics, Healthcare, Gaming, PropTech, and Marketplaces. I build fast, conversion-focused interfaces using React, Next.js (App Router & Pages Router), Angular, TypeScript, Tailwind CSS, Material UI, and ShadCN/UI, paired with modern state management (Redux Toolkit, React Query, Zustand) and smooth animations (Framer Motion, GSAP). On the backend, I develop scalable REST and GraphQL APIs using Node.js, NestJS, and Express, handling authentication (JWT, OAuth, NextAuth), role-based access control, real-time systems (WebSockets, Socket.io), payment gateways (Stripe, PayPal), and third-party integrations including CRMs, LMS platforms, and OpenAI APIs. I design databases that don’t collapse under traffic, working with MongoDB, PostgreSQL, MySQL, Redis, and ORMs like Prisma and Mongoose, and deploy confidently using AWS, Docker, CI/CD pipelines, Vercel, Render, and NGINX. Alongside full-stack development, I build AI-powered chatbots, agents, and automation systems using ChatGPT, Generative AI, n8n, Make.com, and Zapier. These systems handle real business workflows such as lead qualification, customer support, scheduling, ticket routing, reporting, and internal operations, connecting chatbots with databases, CRMs, messaging platforms, and custom APIs. Instead of isolated bots, I design end-to-end AI workflows that start from user input, pass through AI decision logic, and finish with real execution—updating systems, triggering workflows, sending notifications, and generating reports. If you’re looking for a Full-Stack MERN / MEAN Developer who also understands AI automation and real-world scalability, send an invite. I’ll respond with a clear technical plan for your project.

I fix complex Webflow, custom JS, and Supabase problems fast — especially when previous freelancers failed. I'm a Brussels-based front-end developer with 20+ years of experience in UX/UI, custom CMS dev, Webflow, and WordPress. I'm known for solving tricky problems and finding clean, elegant solutions where others get stuck. Whether it's a pixel-perfect site from Figma or an untangled CMS, I think creatively and deliver fast, reliable results. I'm a Level 2 CMS-certified Webflow expert and have built everything from sleek landing pages to complex, dynamic platforms — directories, blog networks, and data-driven systems with Supabase, OpenAI, Azure, and automation through Make, Zapier, and Airtable. That means one person handles both the front end and the logic behind it, instead of you coordinating two. Most recently, I built and run iGlowly — a data-driven SaaS platform with a custom backend and a multilingual CMS — so large, dynamic, data-fed sites are my normal territory. I also run e-commerce UX audits and conversion-focused prototypes for Shopify stores: I review your customer journey, find where shoppers get confused or drop off, and build a clickable prototype showing the improved experience. With 100% Job Success and $100K+ earned on Upwork, I'm independent, proactive, and focused on quality — from clean code to smooth user experience. Let's build something great — and make it smart. 💡

I Build AI Systems That Still Work After You Add The Next One. 20 Years of Full-Stack Development. If you're reading Upwork profiles, you're probably deciding between: Option A: A developer who can build what you asked for Option B: Someone who knows what you actually need (and what breaks if you get it wrong) I'm Option B. The Problem With Most AI Development Every AI demo looks clean. Every integration sounds "seamless." Then reality shows up... - API conflicts that surface 6 months later - "Native integrations" that are actually brittle webhooks - Systems that work today but block everything you want to add tomorrow - Technical debt that outlives employees I've spent 20 years building systems. The last 3 years, I've specialized in building AI implementations that don't create these problems. What I Actually Do... I don't just build AI tools. I architect AI systems which... ✓ Work with your existing tech stack (not against it) ✓ Stay flexible when you need to add the next tool ✓ Scale without requiring rebuilds every 6 months ✓ Don't create hidden dependencies that trap you later My specialty: Taking what you think you need and showing you what will actually work in your environment long-term. Real Projects, Real Results AI-Powered Real Estate Platform (2024) - Built custom AI lead qualification system integrated with existing CRM. Avoided $40K in vendor contracts by using native APIs instead of third-party middleware. System processes 300+ leads/day with zero integration failures. Healthcare Appointment Automation (2023) - Replaced fragile Zapier chain with purpose-built AI system. Eliminated 8-12 hours/week of manual cleanup. Zero missed appointments in 14 months of operation. Financial Services Document Processing (2024) - Custom AI implementation that actually reads loan documents and routes to correct workflows. Reduced processing time by 73%. Built to work with their compliance requirements, not around them. The pattern: These clients didn't need more AI tools. They needed someone who could make AI work inside their actual business reality. Technical Capabilities (What I Build With) AI & LLM Integration: Claude, GPT-4, Custom LLM implementations, Prompt engineering, RAG systems, AI agents Core Development: React, Next.js, Node.js, TypeScript, Python, PHP Mobile: React Native, Swift (iOS), Kotlin (Android) Infrastructure: AWS, Azure, Vercel, Database design (PostgreSQL, MySQL, MongoDB) Integration Specialist: Stripe, Google APIs, Zoom, Calendly, Zapier alternatives, Custom API development My team has 75,000+ hours of paid development work. Who I Help: ✓ Business owners making AI decisions with financial consequences ✓ Companies that need AI to work with existing systems ✓ Leaders who think in years, not sprints ✓ Anyone who's been burned by "seamless integrations" before Before I write a single line of code, we'll discuss... 1. What you're using now 2. What you want to add next 3. What you'll need in 6-12 months Because AI decisions aren't isolated anymore, they're architectural. Every tool you add becomes the foundation something else has to build on. My job: Make sure what we build today doesn't become technical debt tomorrow. What Clients Say: "Gus saved us from a $300/month AI receptionist that would've created 6 months of cleanup work. His solution was better, cheaper, and actually integrated properly." -- Real Estate Operations Director "He didn't just build what we asked for he showed us what would actually work. That's worth more than the development itself." -- SaaS Founder "Finally, a developer who understands that 'it works' isn't the same as 'it works with everything else." -- Healthcare Tech Manager The Conversation Starts Here... When you message me, you're talking directly to me, not a PM, not an assistant. Tell me: - What you're building - What you're worried might break - What you've already tried I'll tell you: - What's actually safe - What breaks (and when) - What order makes sense Let's build AI systems that still work after you add the next one. Gus Skarlis 20 years building software. 3 years fixing what "seamless integrations" broke. → Message me. Let's figure out what you actually need.
