Full-stack TypeScript platforms, multi-tenant SaaS, APIs and integrations, and React Native mobile apps
01 / The problem
What it looks like from your side
Your business has outgrown its plugins and spreadsheets, and the next step is software of your own.
A custom platform is a big decision, so I treat it like one. Before any code, you get a written architecture note: the data model, what runs in queues, which services it talks to, where it's hosted and what it costs to run. You approve that, then the build starts with the smallest slice that does real work.
What I build:
Commerce platforms. Several storefronts sharing one stock pool, order verification, courier and fulfillment integrations.
Multi-tenant SaaS. One codebase serving many customers, with separate data, roles and billing hooks.
APIs and integrations. Typed APIs, webhooks and background jobs that connect the systems you already use.
Mobile apps. iOS and Android apps in React Native, with native cart and checkout where the business needs it.
The usual stack is TypeScript end to end: Node.js with Fastify, PostgreSQL, Redis and BullMQ for queues, React or Next.js on the front, React Native for mobile, and Cloudflare in front of it all. If your team already runs something else, I work with that instead of rewriting it.

03 / Method
What I do, step by step
01Map the workflow, the data and the people who touch it
02Write the spec and the architecture note: data model, queues, integrations, hosting
03Build the first useful slice and put it in front of real users
04Add the rest in small, tested releases
05Set up monitoring, backups and the hand-over documentation
04 / Deliverables
What you get
A running platform or app in your accounts
Architecture note and runbook
Monitoring, backups and deploy pipeline
The number I report at the end
The workflow the platform replaced: hours saved, orders handled, errors removed, uptime
Typical timeline: Weeks for a first release; months for a full platform
