We’re kicking off development of a MVP (Minimum Viable Product). The goal is simple and focused: deliver a working self-care app for SIM/eSIM management + wallet integration in 3 weeks. This MVP will prove our core product: Onboarding & KYC → users sign up and verify identity Wallet basics → see balances, top up eSIM management → browse, activate, recharge Dashboard → single overview screen Infrastructure → AWS, CI/CD, monitoring Everything else (FX, Crypto, Messaging, Card Issuing, Admin) is Post-MVP. These are already in the backlog so scope is transparent, but they’re not in play now. What you need to know 3 cycles (1 week each) → Foundations, eSIM Core, Dashboard & Launch Issues are already created in Linear → tagged with MVP / Post-MVP, P0 / P1, and role labels (FE, BE, DevOps) Definition of Done → code merged, tested, deployed to staging, documented in Linear Daily standups + end-of-week demo → transparency is key This is a tight, 3-week sprint to market. If it’s not MVP-critical, it’s not in scope.

Hi, This is Elias from Miami. I’ve reviewed your description and I understand the goal is to deliver a focused MVP in 3 weeks for a self-care app handling SIM/eSIM management with wallet integration. With 10+ years of experience shipping MVPs under tight deadlines, I’m very interested — I’ve worked on telecom and fintech apps where onboarding, KYC, and dashboard clarity were mission-critical. Please check my past work, which aligns well with your scope. I’d love to connect and discuss how to move fast while keeping quality high. A few clarifications I’d like to make upfront: Q1: For KYC, are you planning to integrate with an existing provider (e.g., Onfido, Jumio) or do you want a lightweight in-house flow for the MVP? Q2: On wallet top-ups, do you need real payment gateway integration now (Stripe, PayPal, etc.), or is a mock flow acceptable for proving the concept? Q3: For eSIM management, do you already have APIs from telco partners ready, or should we simulate some flows to meet the 3-week timeline? Q4: Regarding monitoring on AWS, do you prefer something lightweight (CloudWatch, basic alerts) or a more robust setup with dashboards (e.g., Datadog, Grafana)? Looking forward to hearing from you. Regards, Elias

Three weeks is a tight but achievable window are you open to parallel workstreams (FE/BE/DevOps in sync) to hit it? I’ve delivered MVPs under similar timelines, with AWS infra, CI/CD pipelines, and mobile-first frontends connected to secure APIs. The Linear-driven workflow you’ve outlined fits perfectly with my agile approach: clear P0/P1 scoping, daily updates, and end-of-week demos to keep momentum. I’ll focus only on the MVP-critical scope—KYC, wallet basics, eSIM management, and dashboard so we ship fast, tested, and staging-ready. Expect a lean, production-grade MVP you can demo confidently by week three. Ahmed

Hello, I can help you deliver your MVP self-care app within the 3-week window, focusing strictly on the P0 scope: onboarding & KYC, wallet basics, eSIM browsing/activation/recharge, and a clean dashboard. I’ll work in weekly cycles aligned with your Linear issues, merging code into staging with CI/CD pipelines on AWS, and providing daily standup updates plus end-of-week demos. The app will be lean, secure, and production-ready for MVP validation, with clear documentation so your team can continue building out the Post-MVP backlog afterward. Questions: – Do you already have a preferred mobile tech stack (React Native, Flutter, or native iOS/Android) for the MVP? – Which KYC provider should be integrated for onboarding (e.g., Onfido, Jumio, custom API)? – Should wallet top-ups and eSIM purchases be handled through an existing payment gateway, or should I integrate one during the MVP phase? I am a TOP Rated Freelancer, and you can check my reviews here as well: https://www.freelancer.com/u/kamran2012 Looking forward to potentially working together on this project. Thanks and Best regards, Kamran.

OVER 10 YEARS OF EXPERIENCE IN IT, HIGH QUALITY DELIVERY Hi, James! The hardest part of a 3-week MVP sprint is avoiding scope creep while still delivering a polished, reliable product—but that’s exactly where I can help. I’ve been through similar high-pressure builds where onboarding, wallet, and core features had to be shipped fast without sacrificing stability. The key is setting up a solid foundation in the first week (AWS, CI/CD, monitoring), then moving quickly into eSIM flows and dashboard without getting sidetracked by Post-MVP backlog items. I’ve got hands-on experience with KYC flows, wallet integrations, and managing telecom APIs, so I can hit the ground running. I work well in daily standups, and I’ll keep everything documented in Linear so progress stays 100% transparent. At the end of 3 weeks, you’ll have a working, demo-ready MVP that proves your product’s value and is ready to evolve into the full vision. Let’s get this sprint started!
