🚀 Hi, I’m Jec — your AI-Powered Vibe Coder & App Builder.
I specialize in building AI-driven platforms that simplify workflows, automate tasks, and integrate seamlessly with your existing tools. I’m the developer behind EVA, a Virtual Assistant Management Platform built entirely on Replit, helping professionals and teams cut admin work by 70% with automation, AI document processing, and CRM integration.
I recently worked on an Italian project where I built a custom CRM from Excel data, automated compensation calculations for collaborators, tracked patient payments, and managed budgets and deductions — all inside one system.
💡 If you’re looking for a developer who can turn complex processes into clean, automated, and scalable solutions, I’d love to help bring your project to life.
Let’s connect and build something that saves time, reduces errors, and delivers results fast.

Need a marketplace developer who has actually shipped two-sided platforms? That is all we do.
I lead delivery at Roobykon Software, a dedicated marketplace developer and Sharetribe developer team. I help founders build two-sided marketplaces, booking platforms, and multi-vendor marketplace MVPs, the kind that connect buyers with sellers, hosts with guests, or clients with service providers. Think Airbnb, Etsy, Turo, TaskRabbit, or Booking, built for your niche.
Why founders pick me:
🔹 150+ successful marketplaces launched globally
🔹 5-week MVP delivery, from idea to a working, revenue-ready product
🔹 Trusted for 14 years in commercial delivery
🔹 Serving customers across 50+ countries (Europe, North America, and MENA)
🔹 Built SaaS trusted by 3000+ users worldwide
🔹 Scaled a Minimum-Viable-Product platform to $3M in investment
🔹 Platforms ranging from lean MVPs to multi-million-dollar ecosystems
🔹 Delivered for clients in e-learning, real estate, healthcare, rentals, and more
What I build:
🔸Two-sided and multivendor marketplace platforms (Sharetribe, Sharetribe Flex, Ruby on Rails, Node, Next.js)
🔸Booking, reservation, and scheduling systems with availability management
🔸Reverse and B2B marketplaces where buyers post requests and providers apply
🔸Directory and listing platforms with map-based search
🔸Migrations and rebuilds from Bubble, WordPress, WooCommerce, Shopify, and Magento
🔸Niches I have shipped in: rentals, on-demand and gig services, home services, real estate, logistics and delivery, events and ticketing, e-learning, healthcare, wellness, and B2B and ecommerce marketplaces.
Payments and marketplace mechanics we know cold:
🔹 Stripe and Stripe Connect (Standard, Express and Custom): escrow holds, commission splits, platform fees, and payouts
🔹 Multi-party and multi-currency payments, subscriptions, and tax automation (Stripe Tax, Avalara, TaxJar)
🔹 Vendor onboarding, dual user roles, admin panels, and vendor dashboards
🔹 Real-time chat, notifications, ratings and reviews, and identity verification
The team behind your build:
Our people cover the full stack, so you get one accountable partner instead of five freelancers. That includes Sharetribe developer, full stack developer, web developer, React developer, Angular developer, Node.js developer, and if required WordPress developer and Bubble developer skill sets, plus product and business analysis to turn your idea into a clear, buildable scope. Once launch is done, we support growth too: website development, SEO, and organic growth to bring your first users in.
How we work (the value you actually get):
➜ We scope honestly: realistic timelines, no overpromises, and a straight answer on what to cut for a lean MVP.
➜ We think like product architects, recommending proven APIs and tools over custom builds wherever it saves you money.
➜ We stay transparent from discovery through QA, deployment, and post-launch optimization.
➜ We position as a partner, not a vendor: technically fluent, and honest about fit before you spend a dollar.
If you are building a Sharetribe marketplace, a two-sided platform, or a marketplace MVP and want a team that has done it 150+ times, send a short message about your product.
Happy to give you a straight, practical read on scope and timeline on a free consultation.
