I’m rolling out email-based one-time-password verification for both my iOS and Android apps and I want the messaging to run through Amazon Simple Email Service. I don’t yet have an SES account, so the job starts with creating and configuring one from scratch—moving it out of the sandbox, verifying the sending domain or address, and generating production-ready SMTP/API credentials. Once the service is live, I need the full OTP flow implemented: generating secure codes on the backend, sending them through SES, and exposing a clean endpoint that the mobile apps can hit to request and validate the codes. The final result should allow a user to enter their email, receive the OTP within seconds, and use it to confirm their account—all with deliverability and rate-limiting best practices in place. Deliverables • SES account setup, domain/email verification, and sandbox removal • Back-end logic for code generation, storage, expiry, and validation • REST (or GraphQL) endpoint documented for the iOS and Android teams • Test plan proving successful delivery and validation in both apps • Brief handoff guide so my team can maintain and monitor SES going forward If you’ve integrated SES for transactional email before and are comfortable handling security around OTP workflows, I’d love to get this moving right away.

Hello, Not satisfied? You don’t pay. I can help you build a robust, secure OTP system using Amazon SES. I have experience moving AWS accounts out of the sandbox and configuring the necessary DNS records (DKIM, SPF, and DMARC) to ensure your verification emails hit the inbox, not the spam folder. I focus on creating "stateless" or secure temporary storage for codes to ensure the validation process is both fast and unhackable. I have structured this project into 4 clear milestones: 1) AWS Infrastructure: Setting up the SES account, verifying your domain, and securing production access. 2) OTP Logic & Security: Building the backend engine for secure code generation, expiry (e.g., 5-minute windows), and rate-limiting. 3) API Integration: Developing the endpoints for your mobile apps to request and verify codes. 4) Testing & Handover: Providing the test plan results and your team’s SES maintenance guide. I will ensure that the system handles "retry" logic correctly so your users aren't locked out or able to spam your SES quota. A few quick questions to get started: 1) What backend language/framework is your app currently using (e.g., Node.js, Python, PHP)? 2) Do you have a preferred database for temporary OTP storage (like Redis or PostgreSQL), or would you like me to recommend a lightweight solution? 3) Since you are rolling this out to iOS and Android, would you like me to include "email templates" that match your app's branding? Kind regards, Zander
