I build custom Amazon seller software — SP-API dashboards, repricing engines, PPC tools, and Keepa-powered research platforms. 70+ tools shipped over 7+ years, including sellerbot, seller-shark and sellerwiz. I work with Amazon sellers, agencies and SaaS startups who need marketplace data turned into automated, scalable software — whether that's a full multi-tenant platform or a single API integration that has to be right. What I build Amazon Seller Dashboards — profit tracking, inventory monitoring and sales analytics on real-time SP-API data FBA/FBM Automation — repricing engines, inventory alerts, order management, multi-channel sync Amazon PPC Tools — Advertising API integration, keyword automation, bid optimization, campaign performance tracking Keepa API Integration — price history tracking, sales rank analysis, deal alerts, historical data dashboards Multi-tenant SaaS Platforms — white-label Amazon tools for agencies, Chrome extensions, and MWS-to-SP-API migrations Recent work A reporting dashboard handling SKUs with real-time SP-API sync A Keepa-powered product research platform now used by Amazon sellers Automated SP-API dashboards that cut a seller's manual reporting time Stack PHP (Laravel), Python (FastAPI/Flask) and Node.js on the backend. React and JavaScript on the frontend. MySQL, PostgreSQL and MongoDB. AWS Lambda, S3, RDS and EC2 for infrastructure. 100+ API integrations across e-commerce, payments, shipping and CRM. How I work I start by scoping the actual problem before quoting — if SP-API rate limits or report latency will constrain what you're asking for, you'll hear it upfront rather than three weeks in. You get documented code, a working staging environment, and a handover you can give to another developer without needing me. Send me your requirements and I'll come back within a few hours with a plan, a timeline and a fixed scope.
