API RESTful Jobs

I need a streamlined link between Order Desk and ShipStation that, the moment an order is submitted to ShipStation, pulls the customer’s JPEG artwork and pushes it straight to our sublimation printer without any manual steps. Here’s the exact flow I have in mind: • Order Desk sends all customer information to ShipStation • As soon as that order reaches ShipStation, your code fetches the JPEG file from the the product variantion ("print_url") • The file is then delivered automatically to the sublimation printer’s API/print queue so production can start immediately. Core requirements • Robust, documented use of both the Order Desk and ShipStation APIs. • Error handling that retries gracefully and logs failures. • A simple con...

I’m ready to move from concept to a production-ready API and need someone comfortable owning the entire backend stack end-to-end. We’ll build the service in Python using FastAPI, with an emphasis on clean architecture, strong typing, and well-documented, idiomatic code. The service will persist data in PostgreSQL, so you should be confident in schema design, migrations, and query optimization for that engine (e.g., via SQLAlchemy/SQLModel and Alembic). The scope is intentionally focused: expose a well-designed JSON/REST API that can be consumed by both a front-end application and third-party clients. Core backend concerns—authentication, API versioning, consistent error handling, and a minimal but meaningful test suite—are considered part of “done means done...

I’ve wired a Spring Cloud API Gateway in front of a Spring Boot micro-service. Every endpoint behaves perfectly in Postman, yet from the browser the preflight OPTIONS request is being rejected and the actual call never reaches the service. So far I have: • exposed the routes through the gateway, • added a CORS configuration class inside the micro-service, and • verified that the standard Access-Control headers are present when I test with Postman. Still, the browser refuses the call, flagging a CORS preflight problem. I need someone who can quickly inspect the gateway filters, global CORS settings and any missing headers, show me why the OPTIONS handshake fails, and patch the configuration so GET/POST/PUT requests flow from any modern browser without err...

I’m working on a Java Spring Boot micro-services application and need a seasoned hand from Pune to straighten out a few points and help me close some production Jira tickets. Most of my questions revolve around how the services talk to each other—specifically, how data moves between them in both synchronous calls (REST, gRPC or similar) and asynchronous flows (message queues, Kafka, etc.). I’d like you to walk me through the current interaction patterns, point out bottlenecks or anti-patterns, and suggest improvements. At the same time, I’ll share a small batch of Jira issues that are already reproduced in our lower environment. They typically involve cross-service data consistency or timing problems. Your role is to propose—and, if feasible within the scop...

I’m looking to put a clean, command-line–driven framework around Apache JMeter so I can run consistent performance tests against our HTTP/HTTPS REST-based APIs straight from CI. The goal is a self-contained repo (or folder structure) where I can drop in new endpoints, update a few properties, and kick off a full test with one shell command. Here’s what I need delivered: • A scripted JMeter 5.x/CLI harness (bash or cross-platform) that downloads dependencies, spins up test runs, and stores results in time-stamped folders. • A reusable test plan template with variables/property files so endpoints, payloads, and thread groups can be edited without touching the .jmx file. • Automated HTML dashboard generation plus a single line summary (throughput, average...

I’m kicking off Phase 1 of a lifestyle-sharing social network and award receiving and monetization need an experienced developer in India to transform the concept into a live web app. In this initial milestone the scope is deliberately lean: users must be able to register, build rich profiles, and connect through friend requests.

You may choose the stack (React or paired with Node.js, Django, or a similar framework fits well), but the result must be secure, responsive, and easy to extend. I’ll provide UI wireframes; you’ll turn them into production-ready components, wire up authentication, and expose well-documented REST or Gra...

I need an experienced Laravel hand who can move confidently between three areas of work: creating new RESTful endpoints, expanding the web-app, and clearing a steady list of bugs.

I’m running a 6ammart backend and want users to receive their one-time passwords through WhatsApp via Msg91. This is my first OTP integration—there’s no legacy provider to migrate from—so the job is a clean setup rather than a replacement. The OTP should fire only on two events: • new user registration • password reset requests I already have the official Msg91 WhatsApp API documentation and will share the keys, templates, and sandbox numbers as soon as we start. Your task is to wire everything up in the 6ammart codebase, make sure the correct templates are called, and verify that messages are delivered within the usual WhatsApp time-to-live window.

I’m kicking off a brand-new Laravel build and want to set it up right from day one. The core of the job is threefold: implement the first round of features, harden the codebase against future bugs, and keep performance fast as we grow. At this early stage there’s no legacy code to untangle, so you’ll have full control over architecture choices—Laravel 10, PHP 8.x, Eloquent ORM, Redis or whatever stack extras you recommend. The initial feature set needs to cover: • Secure, role-based user authentication (email + social logins) • Clean RESTful API integration points so our future mobile app can plug in easily • Advanced, filterable search that remains snappy even with large data sets While building, unit tests and sensible naming conventions ...

I’m building a web-based SaaS platform that gives our corporate teams complete control over user accounts while speaking fluently to the rest of our tech stack.

Equally important is the integration layer. The service needs to exchange data in real time with our CRM, ERP, payment gateway, and the in-store POS system we already run. Please design the APIs so additional connectors can be added later without touching the core logic. Tech direction is open, provided the solution is multi-tenant, scalable, and shipped with thorough automated tests. OpenAPI (Swagger) docs for every endpoint and a clean, modern browser interface...
