Engineering
Monthly engineering support from a team that has built marketplace systems at scale.
The Problem
Most marketplace founders at the growth stage have the same technical bottleneck. They need to move fast on their product but either lack internal engineering capacity, are paying too much for the wrong talent, or are stuck on platforms that cannot scale. The options feel limited: hire full-time (expensive, slow to ramp), use no-code tools (fine until they break), or work with a dev shop that does not understand marketplaces. There is a fourth option. We work on a monthly basis, we know marketplace architecture, and we have seen almost every technical problem at your stage.
What I Do
We work with you on a rolling monthly basis, scoped to your current project needs. No long-term retainer lock-in, no project proposals that take three weeks to negotiate. You get experienced engineers who understand marketplace systems, available when you need them.
We have built supply-demand systems, booking flows, search and discovery layers, fraud detection, payment processing, and the operational tooling that marketplace teams depend on. The context comes with us.
Frontend, backend, database, infrastructure, AI integrations, third-party APIs. We do not hand work off to specialists for every layer. One team, end to end.
We work inside your existing codebase and with your existing team, not in a silo. Code reviews, documentation, and knowledge transfer are part of how we work, not extras.
Areas of Focus
Full product builds, feature development, and ongoing engineering for marketplace web and mobile applications. React, Next.js, React Native, Node, Python, and the infrastructure that supports them.
Helping non-technical founders understand what AI can actually do for their marketplace, then building it. Search and recommendations, fraud detection models, automated supply quality scoring, chatbots, and internal tooling that removes manual work.
Moving marketplaces off Lovable, Replit, Squarespace, Wix, WordPress, and other platforms that have hit their ceiling. Full migrations to self-hosted, production-grade infrastructure that you own and can scale. Done right the first time.
Fraud prevention systems, identity verification integrations, chargeback reduction, off-platform leakage detection, and the security architecture that protects your marketplace as it grows. We have seen what breaks and when.
Schema design, query optimization, indexing strategy, and database selection for marketplace workloads. Whether you are on Postgres, MySQL, MongoDB, or evaluating a migration, we make sure your data layer can support the scale you are building toward.
Core Web Vitals, Lighthouse score improvements, image optimization, caching strategy, CDN configuration, and the frontend performance work that directly affects SEO ranking and conversion. Fast sites convert better and rank better.
Structured review of your marketplace UX: search and discovery, listing pages, checkout flow, onboarding, and supply-side tools. We identify the friction points costing you conversion and prioritize fixes by impact.
Stripe, Braintree, Adyen, and custom payment flow architecture. Split payments, escrow, payout scheduling, multi-currency, and the compliance requirements that come with processing money between buyers and sellers at scale.
What You Get
Who This Is For
Marketplace founders who need to build but do not have the internal engineering capacity to do it right. Best fit if you are running on a platform that cannot scale, need to ship a specific feature fast, or want a technical partner who understands the marketplace context without needing to be onboarded on it.
