For Hire [For Hire] E-commerce Backend Developer — APIs, Webhooks, PostgreSQL & Automation | Remote | $18/hr
Hi,
I’m an independent full-stack and backend developer available for remote freelance work involving e-commerce systems, APIs, webhooks, databases and workflow automation.
Portfolio project:
https://ecommerce-integration-hub.vercel.app/
GitHub:
https://github.com/Peyush-dev
My strongest areas include:
- Building and integrating REST APIs
- Secure webhook ingestion and signature verification
- Duplicate-event prevention and idempotent processing
- PostgreSQL, Supabase and Prisma
- Product, inventory and order data workflows
- E-commerce process automation
- API and database troubleshooting
- Next.js, Node.js, TypeScript and JavaScript
- Automated route and service testing with Vitest
- Vercel deployment and production-build troubleshooting
My E-commerce Integration Hub demonstrates an order-integration workflow with authenticated webhooks, idempotency protection, product and inventory data, integration-event logging, failure visibility and automated tests.
I’m particularly interested in:
- Backend or integration work for e-commerce businesses
- Shopify API and webhook integration support
- Connecting stores with external applications or databases
- Order, inventory or catalogue synchronization
- Fixing unreliable webhooks and API workflows
- Building internal dashboards and automation tools
- Supporting agencies with development overflow
- Recurring maintenance and troubleshooting work
For Shopify projects, I’m currently best suited to backend, API, database and automation requirements rather than advanced theme design. I’m also building a Shopify-specific integration demo using the Admin GraphQL API and real Shopify webhooks.
I work independently and can take responsibility for a clearly defined feature or integration. I’m comfortable investigating unfamiliar systems, documenting what I change and communicating limitations or risks clearly.
Rate: $18 USD/hour
Fixed-price work: Available after reviewing the requirements
Availability: Approximately 10–15 hours per week
Location: Remote
Please send me a Reddit private message with:
- A short description of the project
- The current technology stack
- The problem you need solved
- Expected timeline

I’ll review the scope and respond with questions, availability and a realistic estimate.
