Project details
I build fast, large-scale data grids and tables for SaaS products. If your table slows down past a few thousand rows, freezes on filtering, or cannot handle the data your users need, I fix it. I work in React with AG Grid, backed by Node and PostgreSQL, using the server-side row model so filtering, sorting, pagination, and editing run on the backend and stay fast at any scale. I build inline editing, column controls, exports, and role-based permissions, and I can take over a slow grid you already have. I have built grids in production handling millions of records, Recent work includes an enterprise SaaS platform with complex workflows and permissions, and a SaaS analytics platform tracking more than 1.3 billion user sessions. I work directly with you. No outsourcing, no handoffs. Send me your data, your stack, and what users need to do, and I will tell you exactly how I would build it.

Whether you are launching a SaaS product from scratch, extending a live platform, or taking over a codebase a previous developer left behind, I build production-ready applications across web and mobile that founders and product teams rely on. One platform I helped build tracks more than 1.3 billion user sessions.
As a full-stack SaaS developer, I build web on React and Next.js and mobile on React Native, so one developer owns your whole product, not just half of it. From billing systems and real-time dashboards to production iOS and Android apps, I ship the full thing and stay accountable for it.
