I’m building a high-volume temporary email service and need the core backend engineered end-to-end. The system should comfortably serve about 20,000 simultaneous users while guaranteeing each inbound or outbound message reaches its recipient in under 20 seconds. Functionally, the service must speak SMTP and IMAP for traditional clients and expose an API for web and mobile integrations. If you have a preferred protocol-friendly framework or any additional approach that can boost performance, I’m open to it as long as it is production-ready, secure, and built for horizontal scaling. I’m happy to negotiate a fair budget once you outline your proposed stack, previous projects that show comparable traffic or throughput, and an estimated timeline. The sooner we can get a stable MVP into staging, the better, so please include realistic delivery milestones alongside your quote. In short: rock-solid delivery speed, resilience under load, and clean extensible code are non-negotiable. Let me know how you plan to achieve this and what you’ll need from me to start immediately.

I am ready to Mow. I’m fully comfortable extending an existing backend and database — no Supabase, no BaaS shortcuts, no risky migrations. How I’d Approach Your Build - Blueprint-driven execution: I’ll work directly from your 20-page Master Technical Blueprint and “Definition of Done,” module by module, with clear checkpoints. - Mobile-first UX: Complex volunteer flows (commitment, rosters, group events) will feel simple and fast on a smartphone browser. - Privacy by design: Address visibility is enforced at the API level — never exposed on public feeds, only revealed after commitment, and role-checked for group leads. - Grant-safe reporting: Impact reports (hours volunteered, fines saved, equipment usage) will be accurate, auditable, and export-ready — because funding depends on it. - Immediate unblock: The login/auth issue gets fixed first so momentum isn’t lost. Why I’m a Good Fit - You get a builder, not just a task-taker - You get someone who understands nonprofit accountability and grant pressure - You get disciplined delivery for a 45-day, fixed-scope sprint I’m ready to review the full Master Technical Blueprint, confirm milestones, and move straight into kickoff so you can hit your Spring launch with confidence.

Hello, I can design and implement a high-performance, horizontally scalable backend for your temporary email service, built to reliably handle ~20,000 concurrent users with sub-20-second message delivery. Approach (High Level) SMTP/IMAP–compatible mail handling with queue-based processing for guaranteed delivery speed API-first backend for web/mobile integrations Event-driven architecture (message queues, workers) for resilience under load Horizontal scaling with stateless services and optimized data storage Security-focused design (rate limiting, abuse prevention, isolation) I’m happy to propose a production-ready stack (cloud-native, containerized) and can justify each choice based on throughput, latency, and fault tolerance. I’ve worked on systems with high concurrency, real-time messaging, and heavy I/O workloads, and I prioritize clean, extensible codebases. What I’ll Provide End-to-end backend MVP (SMTP, IMAP, API) Staging deployment Clear milestones and realistic delivery timeline Architecture overview and documentation Once I understand any existing constraints (cloud preference, language bias, compliance needs), I can share: Proposed tech stack Comparable past projects Timeline and budget estimate Ready to start immediately. Best regards, Technosaga Infotech Pvt. Ltd.

Building a high-volume temporary email backend demands more than just handling load—it requires ensuring every message reliably arrives under tight time constraints without compromising scalability or security. Failing to architect for horizontal scaling and protocol compatibility risks missed deliveries and user frustration. With deep expertise crafting resilient email systems tailored to high concurrency, I offer a solution focused on performance, robustness, and clean, extensible design—balancing traditional protocols with modern API needs. Having delivered comparable projects beyond platforms like this, I propose a strategic, limited-rate engagement to establish trust and demonstrate value swiftly. Let’s discuss your priorities and necessary inputs to shape a precise timeline and kickoff plan. Liam Jasson
