Expert Full Stack Developer Needed - one month short contract READ BEFORE APPLYING

@juanjosec63

Hello, I’m excited about the opportunity to support the RewardsX mobile team and help stabilize and optimize your existing Node.js backend during this development phase. With strong experience in Node.js (Express), REST API integration, MongoDB, PostgreSQL, and working with mobile-facing backends, I can assist your Flutter team with endpoint support, debugging integration issues, improving API performance, and ensuring reliable deployments on GCP within your current architecture. I’ve worked on startup environments with distributed teams before, supporting active mobile builds by refining existing codebases rather than rebuilding from scratch, and I’m comfortable collaborating daily with your Chennai team during IST overlap hours. I am available 4–5 hours per day, Monday to Friday, and can commit fully for the 1-month duration; however, I would like to clarify the budget alignment before proceeding, as the listed amount is significantly below standard market rates for this scope. Best regards, Juan

Hi, early fintech apps usually struggle when backend APIs are not tightly aligned with mobile requirements. Small integration gaps can block entire Flutter flows. I am a full stack Node.js developer and I can support your existing Express backend and mobile team without disrupting current architecture. I have worked on API layers for mobile apps, handling MongoDB and PostgreSQL operations, optimizing endpoints, fixing integration bugs and supporting deployments on GCP. I am comfortable working inside existing codebases with Git workflows and distributed teams. Timezone: IST Availability: 4 to 5 hours daily, Monday to Friday Comfortable with the stated startup budget for 1 month. Ready to support immediately. Verma
