Backend Development Services
I build and improve the systems behind websites and applications: APIs, data models, authentication, integrations, background work, and the operational controls needed to run them.
Backend work tied to real workflows
The work can include REST or GraphQL APIs, database design, authentication and authorization, third-party integrations, event processing, validation, error handling, and administration workflows. Requirements begin with who uses the data, what can change it, and what should happen when a dependency fails.
Who this service is for
This service fits teams building a new web application, replacing a fragile API, connecting systems that currently require manual copying, or adding dependable server-side behavior to an existing React or Next.js product.
Process and deliverables
Discovery maps users, data, permissions, integrations, and failure cases. Delivery includes an agreed architecture, reviewable implementation, automated checks where useful, environment configuration, logging, deployment notes, and an ownership handoff.
Security and operations are part of the design
Permissions are kept narrow, secrets stay outside source code, inputs are validated, and sensitive values are excluded from logs. Monitoring, backups, rate limits, recovery steps, and service costs are considered according to the system's actual risk; no security or uptime outcome is guaranteed.

Backend Development questions
What does a backend developer build?
A backend developer builds the APIs, data access, authentication, integrations, and server-side workflows that support a website or application.
Can you connect an existing frontend to a new backend?
Yes. I can document the current data contract, plan a compatible API, migrate consumers in stages, and add error handling and monitoring around the connection.
Do you work with REST and GraphQL APIs?
Yes. The choice depends on consumers, data shape, caching, permissions, tooling, and maintainability rather than a preference for one style.
Can you repair an existing backend?
Yes, after reviewing representative code, production behavior, data risks, deployment access, and the specific failures or delivery bottlenecks.
