I help founders, startups, and growing businesses turn web app ideas into launched, revenue-ready products. My work goes beyond simply completing development tasks. I help clients plan the right features, build the core product, launch faster, and set up the technical foundation needed to support real users, payments, admin workflows, automation, and business growth. I specialize in SaaS platforms, MVPs, dashboards, customer portals, subscription systems, internal tools, and API-driven web applications. I also help founders clean up vibe-coded apps built with tools like Lovable, Bolt, Replit, Same, v0, or Cursor and turn them into stable, production-ready products that can support real users, payments, and business growth. For live applications, I provide ongoing maintenance and product support, including bug fixes, scaling, new features, performance improvements, deployment support, integrations, and technical cleanup. A recent example is Alpha Security, a Netherlands-based security company that was running key operations through paper, spreadsheets, and manual follow-ups. I helped build a custom internal dashboard with multiple modules for security pass applications, job vacancy management, KPI tracking, and customer reviews. The system automated daily submissions and operational workflows, saving the team around 3+ hours every day. I have 6+ years of experience as a Full Stack Developer working with JavaScript and TypeScript across the full stack. My main stack includes React, Next.js, Node.js, Express, MongoDB, PostgreSQL, REST APIs, authentication systems, payment integrations, automation workflows, and production deployments. What makes my approach different is that I think about the product as a business, not just as code. Before building, I help clarify what actually needs to be launched first, which features can wait, and how the product should be structured so it can support real users, payments, admin workflows, reporting, and future growth. When the project is done, you will not just receive source code. You will get a working product, production-ready deployment, clean project structure, documentation, and a proper handover so your team or future developers can continue without confusion. If you have a SaaS idea, MVP, dashboard, customer portal, AI-generated prototype, or existing web application that needs to be launched or improved, send me a message and I’ll help you figure out the fastest practical path to get it live and working.

Integrated systems rarely break on the first successful API call. They break three weeks later: a failed Shopify webhook, an ERP order that never synced, a CRM contact missing from the pipeline, or POS inventory that no longer matches the store. I build and fix the middleware/API layer behind those systems. My strongest work is around Shopify, ERP, CRM, POS, and Laravel-based backend systems where product data, orders, inventory, customers, payments, and reporting all need to stay aligned. What I usually handle: - Shopify / Shopify Plus integrations and custom commerce workflows - ERP and CRM syncs: Acumatica, Salesforce, Zoho, HubSpot, SAP-style systems - POS and inventory workflows: Clover, store operations, loyalty, order flows - Laravel/PHP middleware, APIs, webhooks, queues, cron jobs, retries, and logs - Admin dashboards, reporting panels, and operational data models - Production debugging where the issue is hidden across multiple systems Relevant background: - Built and supported systems handling 24k+ products, 3M+ users, and 2,000+ locations - Led technical delivery across teams of 20+ - Worked across Shopify, Shopify Plus, Magento, BigCommerce, Acumatica, Salesforce, Zoho, Clover POS, Laravel, REST/GraphQL APIs, PostgreSQL, MySQL, AWS, Firebase, and payment systems I also take on SaaS MVPs and React Native app work when the project depends on backend architecture, integrations, subscriptions, analytics, or production stability. If your store, ERP, CRM, POS, or internal dashboard is held together by fragile syncs and unclear data flow, I can help trace where it breaks and make the system reliable.
