For Leonix, a heavy-duty truck parts distributor based in Boca Raton, Florida, we built the store, the supplier panel and the admin panel with our team in Istanbul. On this page you can see how working with a company in Florida goes, what we did in the project and which services we offer.
In the Leonix store, every step from the home page to the product page is built around the OEM number: the search box finds a number regardless of spaces and hyphens, and the product page shows price and stock status next to the buy button. Category and brand pages, a quote form for parts not in the catalog and order tracking without an account live in the same interface.
View serviceThe Leonix API runs on ASP.NET Core and PostgreSQL. Offers from several suppliers for the same part are gathered under one product, stock is pooled across approved offers, and an order draws stock down in cost order. Supplier Excel uploads run as background jobs that validate row by row, and each supplier can only reach its own records.
View serviceLeonix's API, panel and store are built and deployed separately. When code is pushed to GitHub, Jenkins starts the build and deploys the relevant application to the server. Each environment runs with its own database and file storage, so a change can be tried in a separate environment before it goes live.
View serviceMVP development for startups and new products from Istanbul: a written validation question, progress visible on a test environment, your code, written handover.
Cursor, Lovable, Replit, Codex and Claude Code output made production-ready: security audit, fixes shipped as PRs, a permanent CI/CD security gate.
Mobile app development for iOS and Android with Flutter and React Native, from Istanbul: version compatibility, offline use, store release, accounts you own.
AI integration: we connect LLM and agent systems to your existing product and workflows. RAG, document automation, measured accuracy and clear data boundaries.
Technical SEO is never finished, and any release can break it. We build indexing, hreflang, Core Web Vitals, 301 mapping and measurement as one system.
AI engines do not rank, they select sources. We make your site citable with llms.txt, structured data, E-E-A-T, a written crawler policy and WebMCP.
We move Meta and LinkedIn leads into your CRM and feed the sales outcome back through the Conversions API. Self-hosted setup, monthly EMQ and conversion report.
CTO as a Service (fractional CTO): tech leadership without a full-time hire. Architecture decision records, tech debt inventory, vendor and team evaluation.
A fixed-scope audit before your AI agents go to production: agent inventory, least-privilege access map, KVKK/GDPR data flow, audit trail, human approval gates and a roadmap.
The catalog. Leonix sells truck and tractor parts in the US market. The parts come from manufacturers in Türkiye and from suppliers that hold stock in US warehouses, and the same OEM number can be produced by several brands. That is why we built the catalog around the part number: the number is normalized for spaces, hyphens and dots, and the equivalents of the same part from different brands show up in one place. The store, the panel where suppliers upload products and the admin panel where the Leonix team approves and prices them all run on the same API. The whole project is told in the success story.
Going live. The costliest mistakes in an online business are selling a product that is not in stock and a payment that does not match an order. That is why we hold stock briefly during checkout and create the order only from a verified payment notification. We wrote concurrent-order tests so that orders arriving at the same moment cannot exceed stock. A quote form for parts not in the catalog, order tracking without an account and a returns flow are also part of the store. After launch we provide 30 days of support.
How we work. Boca Raton is on US Eastern Time. The shared window with Istanbul is between Florida mornings and the Istanbul afternoon. In the first call we pin down the need, the existing system and the timeline, then move in two-week sprints and show a working demo at the end of each one. The working language is English, and full ownership of the source code passes to you at delivery.
Wherever you are, the first meeting is free, online or in person.
