API REST Jobs

Our online education portal, , is powered by Python—primarily Django with a couple of small Flask services—and everything funnels through a single PostgreSQL instance. Traffic and course data have grown quickly, and the database layer is now the clear bottleneck. What I need is a specialist who can dive into our existing REST-driven codebase, profile the slow spots, and leave us with a noticeably faster, more stable platform. You’ll be looking at query plans, indexes, connection pooling, and any ORM patterns that might be hurting us. If you prefer working directly in SQL rather than through Django’s ORM when performance calls for it, that’s fine; the end goal is speed and reliability. While the stack is firmly Python/PostgreSQL, I’m open to discussing...

I’m commissioning a full-stack portal that mirrors the look and feel of the reference site I’ll share privately (). The core requirement is a secure employee-only environment where every user I create has an individually defined expiry date; once that date passes, their credentials must lock automatically without manual intervention. Key workflow • Admin area: simple interface for me to add, edit, or bulk-import users, set their expiry, and review activity logs. • Authentication layer: token-based login, password reset, and optional SSO if it speeds things up. • Communication tools: at minimum an internal messaging feature so staff can exchange information in real time. I’m open to whether that’s a chat module, lightweight forum, or another app...

I need a full-scale rebuild of the “amigrapes” mobile experience for both Android and iOS. The goal is to replicate the core flow and overall look-and-feel of the reference app while adding the flexibility to grow new features later. Scope of work • Design and code the complete front-end for Android (Kotlin or Flutter/React Native) and iOS (Swift or the chosen cross-platform approach). • Build a secure, well-documented back-end with REST/GraphQL APIs, database, and an admin dashboard that lets me manage products, users, orders, and push notifications in real time. • Implement standard account creation, sign-in, password reset, and push notification permissions from day one; additional auth options can be slotted in once we finalise the spec. • Packa...

I need an Opentext D2 SmartView developer to extend the standard interface, focusing purely on SmartView-side work. The goal is to add two concrete capabilities: • Custom widgets that plug seamlessly into the existing SmartView framework, following OT’s recommended extension pattern and respecting current branding guidelines. • An enhanced search experience that goes beyond default facets, providing faster filtering and richer result previews while keeping performance on par with native SmartView search. You’ll be free to choose the most efficient approach—REST APIs, the SmartView SDK, or other supported hooks—as long as it runs smoothly on D2 25.2 (our current version) and requires no server-side core modifications. Deliverables must include th...

I need a production-ready dashboard built in SAP Analytics Cloud that pulls live data from our SAP HANA system. In addition, the design should allow me to enrich those HANA figures with supplementary feeds coming from a couple of REST APIs and a small relational database we already maintain, so please keep connectivity flexible. The finished story must present our KPIs through interactive charts, clean tables and an intuitive map view. Think drill-down, filter panels and responsive layouts that look just as good on a laptop as on the SAC Mobile App. Performance is critical; the dashboard should open quickly and refresh without noticeable lag, even when running live against HANA. I will provide access to the HANA views, API endpoints and a sample of the external database. You will model t...

I need a single, streamlined tool that can push high-volume messages to both Telegram and WhatsApp through an exposed API. The workflow should be straightforward: I pass a list of chat IDs / phone numbers and message content to your endpoint, the system queues everything sensibly to stay within platform limits, and I get clear delivery reports back. Key points • Platforms: fully support Telegram Bot API and the WhatsApp Cloud / Business API from one codebase. • Core function: send bulk messages (text first; media support is welcome if practical). No separate agent layers or campaign dashboards are necessary. • Optional plus: a lightweight AI-style templating or text-spinning helper for basic personalisation if it adds minimal overhead. • Tech stack is open&mdas...

We need ready (not develpment) and full-fledged ride-hailing solution for both iOS and Android that mirrors the fluid, on-demand experience of Uber while adding a few extras tailored to my market.

I need a production-ready REST API in Azure that lets our existing C# application reach an Azure SQL Database from anywhere, yet keeps the database completely off the public internet. The data involved is general business data, but the connection still has to be locked down. Authentication is two-layered. Human users must pass Microsoft Entra ID with MFA, while the application itself presents an API key on every call—no OAuth2 refresh tokens or certificates for this project. Every request must travel over TLS 1.2+ and be logged for audit purposes. The API will expose read, write and update operations. It must connect to SQL through a system-assigned Managed Identity; no connection strings or passwords are to be stored in code or configuration. Firewall rules must be ignored, as the...

I already have a working application in production, but it now needs fresh capabilities. My main goal is to extend its functionality by integrating selected third-party services (APIs, payment gateways, or SaaS tools that make sense for the platform).

The focus is on new features, but if...

I run a service-based company where too many day-to-day inventory tasks are still handled by hand. The resulting bottlenecks slow our operations and make it hard to scale, so I’m looking for a developer who can design and implement a technology solution that automates our entire inventory-management flow. What I need • A streamlined system—web, desktop or mobile—that records stock movements in real time, updates quantities automatically, and issues low-stock alerts. • Easy integration with our existing billing platform through REST or GraphQL APIs so we never have to re-enter data. • Role-based dashboards for staff and managers, giving each team member exactly the information they need. • Exportable reports (PDF/Excel) for weekly and monthly r...
