    I’m building an end-to-end lending experience for iOS that feels as smooth as Slice or Moneyview. The job covers both sides of the stack: a sleek native iOS front end and a secure, scalable back end with the APIs that power it. On the user side the flow is simple but must be rock-solid. A new customer signs up with email/password, can just as easily use a social account, and once inside can enable Face ID or Touch ID so returning is frictionless. They complete a loan application form, the system instantly checks eligibility, returns an approved amount (or declination), shows a clear repayment schedule, and later lets them review every past loan in a dedicated history screen.

What I’m looking for Strong experience with TypeScript and modern front-end frameworks such as React, , or similar, along with current tooling and best practices. Solid Python skills and hands-o...

    production bugs fix Python back end developers who take up task and bugs You’ll start by replicating the problems in the live environment, trace the root cause across the intertwined front-end and server code db, then patch and test until everything behaves reliably again. Clear, commented fixes pushed to the repo and a brief post-mortem summarising what happened, what changed, and how to prevent a recurrence will mark the job complete. If you can jump in immediately, work fast, and are confident troubleshooting Python web stacks end-to-end, I’m ready to give you access and stay online for quick turnarounds on any questions.

    I run the software division of a growing technology company in خميس مشيط, المملكة العربية السعودية, and we are expanding our in-house engineering team. The immediate need is for highly experienced programmers from India, Pakistan, Bangladesh, or Sri Lanka who can relocate and work onsite with us on a full-time basis. The work spans end-to-end product development: planning features with our product managers, writing clean and well-documented code, performing peer reviews, and shipping stable releases on a regular sprint cycle. We handle both web and mobile solutions, so a strong command of at least one modern back-end language (Java, Python, Node.js) and a front-end framework (React, Angular, or Vue) is essential. Familiarity with RESTful API design, Git-based workflows, and cloud deployme...

    I need a hands-on full-stack developer who can own both the C#/ASP.NET Core back-end and a React front-end. The immediate focus is to build, test, and maintain a scalable web application that cleanly separates concerns yet feels seamless to the end user. On the server side you’ll architect RESTful endpoints with ASP.NET Core Web API, wire them to MS SQL Server, and keep performance in check through efficient queries and thoughtful caching. On the client side you’ll create reusable React components, manage state responsibly, and make sure the UI stays snappy across modern browsers. I expect clean, well-documented code, meaningful unit tests, and proactive communication when a requirement needs clarification. Collaboration is part of the daily routine: you will coordinate with ...

    I need a versatile full-stack developer who can take an idea from blank repo to live deployment. The job covers everything: shaping the architecture, building a responsive front-end, wiring a secure back-end API with a relational database, and wrapping it all in automated tests and CI/CD so the codebase is production-ready. The exact feature map will be finalised together, but expect staples such as secure user authentication, the option to plug in a payment gateway, and a lightweight analytics dashboard. I’m flexible on tools—React or Vue on the client, Node.js, Django, or Laravel on the server—as long as the stack is mainstream, well-documented, and deploys smoothly to AWS (or a comparable cloud). Deliverables • Clean, well-structured repo with README and setup n...

    I need an end-to-end web application, front-end and back-end, that ships production-ready code and is already live on AWS when we shake hands on completion. All development must sit in a clean, well-documented GitHub / GitLab repository so every commit, branch, and pull request is traceable. Core requirement: integrate Exotel’s call-masking API. Calls must flow through virtual numbers, show the correct masked caller ID, and log events (initiation, connection, hang-up, failures) in the database for later analytics. Should future business needs demand it, the codebase must remain flexible enough to swap in Twilio, Vonage, or Plivo without a full rewrite, so keep the telephony layer modular. Deployment target is AWS. A lightweight CI/CD pipeline that builds, runs tests, and promotes t...

    We are building Composey, a new online learning hub, and I need a seasoned full-stack developer to turn the concept into a secure, production-ready web platform where students and educators can truly interact. This is far more than a marketing page—it must function as a lightweight yet powerful LMS with e-commerce. What the site has to do • Two distinct user journeys: students and educators each reach the platform through their own login flow, land on purpose-built dashboards, and see only the resources allowed by their role. • LMS core: upload and stream video lessons, attach PDF resources, and create auto-graded quizzes. Progress tracking and basic reporting should be baked in. • Monetisation: integrate PayPal for one-off course sales and live tutoring booking...
