I am launching a new web application and want the entire backend built in F#. The project must include rock-solid user authentication and two external API integrations: a payment gateway for transactions and social-media endpoints for sign-ups and data sharing. You will have full control over the technology stack on the .NET side, so feel free to suggest frameworks such as Giraffe, Saturn, SAFE Stack or any other F#-friendly tools that help us move quickly while keeping functional principles intact. The frontend can be whatever you are most comfortable with (Fable, React, Svelte, etc.) as long as it talks cleanly to the F# services you create. Key goals • Secure authentication: registration, login, password reset, JWT/session handling and role management. • API integration: connect to a mainstream payment gateway (Stripe, PayPal, or your recommended option) and mainstream social-media APIs for OAuth-based sign-in and posting. • Clean, well-documented code and unit tests so my in-house developers can maintain it after delivery. • CI/CD pipeline scripted in the repo to deploy to a cloud host of our choice (Azure, AWS or DigitalOcean). Deliverables 1. Source code repository with commit history. 2. Database schema and migration scripts. 3. Instructions for local setup and one-click cloud deployment. 4. Brief hand-off session (video or written) walking through architecture and any tricky bits. If your team thrives in functional programming, knows how to keep security tight, and loves integrating third-party services, I’m ready to get started right away.

✋ Hi, there. I can build your web app backend in F# with secure auth, payments, and social API integrations. ✔️ I have rich experience with .NET backend development, F# services, REST APIs, authentication flows, database migrations, payment gateways, OAuth, unit testing, and cloud deployment. I worked on a similar app where I built user login, JWT roles, Stripe payments, social sign-in, API sharing, CI/CD, and developer hand-off docs. ✔️ I can use Giraffe, Saturn, or SAFE Stack depending on your preferred frontend and hosting plan. I will set up registration, login, password reset, JWT or session handling, role management, database schema, migrations, payment gateway integration, and social OAuth endpoints. ✔️ I will keep the code clean, typed, testable, and easy for your in-house developers to maintain. I will also prepare the Git repo, unit tests, environment configs, deployment script, and setup guide for Azure, AWS, or DigitalOcean. Please click the Chat button so we can discuss the stack, APIs, and first milestone. Looking forward to working with you. Best regards, Mykhaylo

With my diverse background, I bring a unique perspective to your F# web application project. While my profile may not show specific experience with F#, I have extensive knowledge in similar functional languages such as Haskell and Python, which gives me a solid foundation to tackle this project. My fluency with multiple programming languages is complemented by my proficiency in core web technologies: .NET, HTML, and JavaScript. These skills poise me to master any new tools or frameworks like Giraffe, Saturn or SAFE Stack that might be needed for this project. In terms of your project goals, I consider clean code and tight security paramount. And while AI is not directly called for here, my AI-first approach always ensures robust yet elegant solutions - traits that seamlessly translate into delivering secure authentication and polished database schema and migration scripts. My problem-solving approach revolves around seamless integration of third-party services, a skill you have explicitly mentioned. I take pride in ensuring that the APIs I work with are simple to use and well-documented, specifically OAuth-based social-media APIs and payment gateways like Stripe or PayPal in this case. Moreover, as an efficient QA tester, I will leave no unit untested so your in-house developers can maintain the system easily.
