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.

I help founders and product teams build, extend, and stabilize production applications. One platform I helped build tracks more than 1.3 billion user sessions.
Over the last 7+ years, I have worked on enterprise SaaS platforms, billing systems, internal tools, analytics dashboards, and real time applications used by thousands of users.
Recent work includes:
➜ SaaS analytics platform with real time dashboards and a React Native SDK tracking more than 1.3 billion user sessions.
➜ B2B SaaS billing platform with Stripe subscriptions, webhooks, PostgreSQL architecture, SendGrid integration, and real time WebSocket dashboards.
➜ Enterprise construction SaaS built with React, NestJS, and PostgreSQL, featuring complex workflows, permissions, and large scale data management.
➜ AI powered desktop platform that converts hand drawn circuits into editable schematics, simulation ready netlists, and live parameter analysis using machine learning and computer vision.
I can help with:
➜ Building new SaaS products.
➜ Extending existing applications.
➜ Taking over and stabilizing codebases.
➜ Next.js and React development.
➜ NestJS and Node.js backend systems.
➜ Stripe subscriptions, billing, and payment workflows.
➜ PostgreSQL database design and optimization.
➜ Real time dashboards and WebSocket applications.

Core Stack:
Next.js, React, TypeScript, Node.js, NestJS, PostgreSQL, Supabase, Prisma, MongoDB, Stripe, OpenAI, Claude, Tailwind CSS, REST APIs, WebSockets, Docker, AWS, and CI/CD.
I work directly with founders and product teams. No outsourcing. No handoffs. I write the code, ship the features, and stay accountable for the result.
If you need a developer who can take ownership of a SaaS product, extend an existing platform, or help bring a complex application into production, send me the requirements, Figma file, or codebase and I will tell you exactly how I would approach it.
