I will build headless ecommerce apis for products inventory and orders
Peter
About this gig
Need an ecommerce backend that connects your sales channels, apps and business operationswithout a storefront redesign?
I develop headless commerce APIs and backend modules for product catalogues, inventory and order management using Java, Spring Boot, MySQL/PostgreSQL and REST.
What I can deliver:
- Product and category APIs
- Stock tracking and inventory operations
- Order creation, status updates and workflows
- Database design, validation and error handling
- Authentication, role-based access and API documentation (where included)
- Integrations with existing apps or business systems (custom scope)
My AtlasHub project includes multi-outlet inventory, POS and business workflows. I use that experience to build maintainable commerce backends tailored to your operations.
Packages cover only their stated endpoints and modules. Storefront design, full checkout/payment flows, hosting and enterprise systems require separate agreement.
Message me before ordering with your current stack, business workflow and required APIs.

I’m a full-stack software engineer with 4+ years of experience building real-world backend systems, APIs, and cloud-based platforms.
Most of my work is around TypeScript, NestJS, GraphQL, REST APIs, PostgreSQL, MongoDB, Redis, Docker, and AWS. I enjoy taking messy ideas or existing systems and turning them into clean, reliable, production-ready software.
I can help with backend development, API integrations, admin dashboards, database design, bug fixing, and deployment. I care about writing code that is easy to maintain, not just code that “works.”

FAQ
What is headless commerce?
Headless commerce separates backend business functionality from the storefront. I develop APIs and backend modules that your existing website, mobile app or other software can connect to.
Will you build my ecommerce website or storefront?
No. This gig focuses on commerce backend development, including products, inventory, orders and APIs. Frontend development is not included.
Which technologies do you use?
My primary stack for this gig is Java, Spring Boot, REST APIs, MySQL or PostgreSQL, Spring Security and Spring Data JPA. Other integrations depend on your requirements.
What is included in each package?
Basic covers up to 2 simple endpoints without database changes. Standard covers one commerce module with up to 5 endpoints and database integration. Premium covers up to 2 modules and 10 endpoints, including agreed authentication, tests and API documentation.
Can you integrate the backend with my existing application?
Yes, depending on your existing technology, API documentation and integration requirements. Please contact me first so I can assess compatibility and provide a custom quote if needed.
Are payments, shipping and deployment included?
Not automatically. Payment gateways, shipping integrations and deployment can be discussed separately and included through a custom offer.
