Senior Full Stack Engineer with 12+ years of experience building SaaS platforms, marketplaces and complex web applications using Node.js, React, Next.js, Ruby on Rails and PostgreSQL. Companies usually reach out to me when their business has outgrown the way their product was originally built. At that stage, the product has already become part of the business. New features take longer to ship. The architecture that once worked now slows the team down. Small changes unexpectedly break other parts of the system. Engineering decisions start affecting business decisions. That's where I do my best work. For the past 10+ years, I've worked with SaaS companies, marketplaces, AI products, and transaction-heavy platforms that needed more than another developer. They needed someone who could understand how the product actually works, make good engineering decisions, and continue evolving it without creating unnecessary technical debt. I don't start by asking which framework you use. I start by understanding how your business works. Because good technical decisions come from understanding the business first. Once I understand that, I help teams modernize legacy systems, simplify complex business logic, improve architecture, build reliable APIs, redesign payment and subscription workflows, optimize performance, and prepare products for the next stage of growth. Most of my work involves products that already have customers, revenue, and years of future evolution ahead of them. If you're looking for the cheapest developer to build an MVP as quickly as possible, I'm probably not the right fit. If your product has become one of your company's most valuable assets and you need someone who can take ownership of complex engineering problems, I'd be happy to talk.

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.
