OAuth Jobs

Schwab API Execution Hardening – 2 Week Contract I’m completing a nearly finished Python trading system (“Hyperion”) and need a senior execution-focused engineer for final hardening and validation. This is NOT a strategy build. This is broker execution stabilization. System Context: • Schwab API integration • Cash account only • Single-leg options only • No spreads • No margin • GUI guardrails implemented (contract limits, capital caps, DTE filters, one position per symbol) • 80–90% complete Scope: • Validate OAuth refresh logic • Harden order submission (idempotency, duplicate prevention) • Confirm proper order lifecycle handling • Implement position reconciliation checks • Add structured logging &bu...

I’m midway through a software development project and now need to fold in a fully-fledged user authentication layer. The current codebase is stable and organised; what’s missing are the sign-up, log-in, password reset, and basic role-based access controls that will make the product production-ready. You’ll be working against an existing Git repo. I’ll grant access and walk you through the structure so you can slot your changes in cleanly rather than bolting them on. I’m open to the usual approaches—JWT sessions, OAuth, or any secure flavour you’re most comfortable with—as long as the solution is standards-compliant and easy for another developer to pick up later. Deliverables • Registration, log-in, log-out, password reset flows ...

The task is to turn my early-stage concept into a working hybrid MVP that will launch first on the web. Everything else in the product can stay bare-bones for now—the priority is a clean, secure user-authentication flow that covers sign-up, login, password reset and session handling. Social or single-sign-on options (Google, Apple, etc.) would be great if they slot in easily. I have user stories and low-fidelity wireframes ready. Choose any modern stack you’re comfortable with—React or Vue on the front end, Node/Express, Django or a similar REST backend, paired with JWT or OAuth for token handling. What matters is that the codebase remains portable so I can wrap it later with Capacitor, Ionic or another bridge for iOS and Android. Deliverables • Deployable web bu...

Responsibilities - Design, develop, and maintain scalable backend services using Python and FastAPI - Build and optimize frontend applications using React - Architect and deploy applications on AWS - Integrate payment systems such as Stripe - Build and maintain user management systems including SSO - Design and integrate AI-driven features including agents, AWS Bedrock, and RAG pipelines Required Qualif...

My small business already runs on Gmail, Chat, Docs, Sheets, Slides and Calendar, yet the mix of consumer versus business accounts and a growing email load (10+ messages a week and climbing) leaves the workflow scattered and privacy settings uncertain. What I need is a clean, well-documented Workspace configuration that respects data-sharing comfort levels while letting every tool work together smoothly. Here is what success looks like for me: • A concise audit of the current accounts that spells out where consumer logins can stay and where a business tier would be smarter. • Step-by-step configuration of Gmail (labels, filters, signature, templates), shared Drive folders, Chat spaces and Calendar sharing so the team can collaborate without chasing links. • Privacy an...

I already run a custom CRM with 10 separate log-ins and now need messaging to live inside it instead of in external tabs. Here is what I’m after: Email • Each user must connect the CRM to their own Gmail account (OAuth preferred, no shared credentials) so they can compose, send, and read replies without ever leaving the system. • I do want to capture the usual engagement metrics—opens and click-throughs—so please wire that into the send pipeline and surface the data on the contact’s timeline. SMS • The same convenience is required for text messages: users type a message in the record view, choose contacts, hit send, and replies appear in the same thread history. Messages have to go out from the individual’s own number/SIM, not a pooled...

I’m building a fully-hosted SaaS product that delivers data analytics without writing code. The stack must be assembled in Base44 (or any comparable no-code environment you prefer) and deployed to either AWS or Azure—whichever lets us scale most smoothly. Core purpose The application will ingest data from standard cloud-based sources and immediately surface insights. Real-time reporting is essential: think live dashboards that update the moment fresh records land. I also need a predictive layer so customers can run quick “what-if” scenarios and receive machine-generated forecasts. Access & security All users will come in through Single Sign-On. I want frictionless login that still meets enterprise requirements, so plan on SAML or OAuth-based SSO with t...

Job Description We are looking for an experienced Azure Data Engineer / Data Integration Specialist to design and implement a robust, scalable data pipeline that pulls data from the Blackbaud API and loads it into an Azure SQL Database using Azure Data Factory (ADF). The goal is to have a fully automated, secure, and monitored ETL pipeline that runs on a scheduled basis and supports future scaling. Project Scope 1. Data Ingestion Connect to Blackbaud REST APIs (OAuth authentication) Handle pagination, rate limits, and API throttling Extract multiple endpoints (e.g., constituents, gifts, transactions, etc.) 2. Data Transformation Clean, normalize, and structure raw API JSON Handle nulls, schema drift, and data type conversions Add audit fields (load date, source system, batch id) 3. Data Lo...

I am preparing to roll out electronic invoicing through ANAF’s e-Factura service and need a Romanian developer who has already been through the full API onboarding process. My immediate goal is to get the initial setup and configuration right the first time, so I’m looking for hands-on guidance rather than generic documentation links. Here is what I expect from our collaboration: • Walk me through the production and sandbox registration steps, including obtaining certificates, configuring OAuth2 authentication, and setting the required headers. • Provide a concise checklist of mandatory request/response fields so I can validate outgoing XML before it reaches ANAF. • Join a screen-sharing session to test one live invoice transmission and interpret the API r...

I have a website in development and I’m now ready to hand off everything tied to the data layer. The site will run on a MySQL back-end and needs three fully functional forms: a general Contact form, a Member registration form, and a Feedback form. Here’s what I need done: • Design and build the MySQL schema so all form submissions are stored efficiently and can be queried later without performance issues. • Create the Contact and Feedback forms with server-side validation and spam protection. • Build the Member registration workflow and hook it to social media login (OAuth) so users can register or sign in with their preferred network; once authenticated, the profile data should be saved to the members table. • Write the necessary CRUD scripts/quer...

I’m kicking off a new Learning Management System and need a developer who can drive the entire build, from the first database table to the final front-end interaction. The immediate priority is the Node.js back-end: you’ll stand up a clean Express (or Nest) codebase, wire in a relational or NoSQL store, and expose secure, documented endpoints. The first API milestone is robust user authentication—JWT or OAuth is fine as long as it’s production-ready and easily extendable for role-based access later on. Once the back-end foundation is solid, we’ll move to the React front-end. I’d like to see the following three features come to life in our initial sprint: • Fresh, responsive user interface skeleton that sets the design language • Core course...
