Backend & APIs
Reliable APIs and databases that scale as you grow
The part users never see but always feel: reliable REST APIs, databases, and auth in Node.js or Laravel — fast, secure, and easy to reason about.
I design data models, build clean REST APIs, and keep the whole thing fast and safe as your product grows. That includes authentication and role-based access, third-party integrations, background jobs, and the boring-but-vital work of validation, error handling, and monitoring. I have built backends in Node.js and TypeScript, PHP and Laravel, and PostgreSQL and MySQL, including a multi-tenant SaaS backend with Row-Level Security across nearly a hundred tables.
If you already have a backend, I can make it faster and safer instead: profiling slow paths, adding sensible caching, tightening security, and paying down the debt that slows your team down.
Starting from
$3,000
per project · or ongoing from $1,500/mo
The figure above is a starting point, not a fixed tier. Your quote depends on scope and complexity — the number of features, integrations, and how much already exists. After a short scoping call you get one fixed price for the whole project, or, for ongoing work, a monthly retainer. Every fixed-price project is split into four equal milestones. I invoice 25% only after each 25% of the work is finished and you have reviewed it, so nothing is paid up front and you never pay for work you haven't seen.
What’s included
Data modelling and database design
REST APIs with validation, auth, and rate limits
Role-based access control and multi-tenant safety
Integrations with third-party services and webhooks
Background jobs, queues, and scheduled tasks
Performance tuning, caching, and monitoring hooks
What you get
- A documented API and database schema
- Auth, roles, and access control in place
- Monitoring and health checks for production
Ideal for
Products that need a solid backend, or an existing one made faster and safer.
Typical stack
How it works
Scope
A short call to understand goals, users, and constraints, turned into a fixed plan, timeline, and quote.
Design
I shape the data model, architecture, and interface, with previews early so we agree before I build.
Build
Four milestones, each ending with a working preview you review before paying its 25% — clean, tested code and regular updates.
Launch & support
Deployment, monitoring, and handover, with post-launch support or a retainer when you need it.
Example work
Real projects where I did this kind of work — the problem, the build, and where it landed.

Backend & APIs: common questions
Can you improve an existing backend instead of rebuilding it?
Yes, and it's often the better call. I profile slow paths, add sensible caching, tighten security, and pay down the debt that's slowing your team — no rewrite required.
How do you keep one customer's data from leaking into another's?
Row-Level Security enforced at the database, not just the app layer. On Tryneth that runs across 97 of 98 production tables, so isolation holds even if application code has a bug.
What do you build backends in?
Node.js and TypeScript, or PHP and Laravel, on PostgreSQL or MySQL — with validation, auth, background jobs, and monitoring treated as part of the job, not extras.
