About this gig

Need an experienced developer for your SaaS? I build new features, fix what slows you down and extend existing web applications, cleanly and with tests.


What I work on:

- New features end to end: database, API, frontend

- Multi tenancy, roles and permissions, audit logs

- Billing and subscriptions with Stripe

- REST APIs and integrations with third party services

- Performance, security and code quality improvements

- Migration of legacy apps to a modern stack


Tech stack: C# and .NET, TypeScript, React and Next.js, Node.js, Python, SQL Server and PostgreSQL, Azure.


How we work:

1. Short review of your codebase and goals

2. Fixed scope and price, larger work in milestones

3. Pull requests with tests and clear descriptions

4. Handover and optional ongoing support
