I’m standing up a large-scale platform that blends Twilio, the WhatsApp Business API, and OpenAI/Claude into a single, fast, secure messaging layer. Dockerized Linux servers are ready to be spun up—we just need a real engineer (no middle-men, no agencies) to wire every piece together and own the stack from day one. The build will lean on both Twilio and WhatsApp. On the Twilio side we’ll be firing off SMS, Voice, and A2P traffic; WhatsApp will cover session and template messaging. Everything must sit behind a clean, well-documented API with solid auth, rate limiting, and logging. Security is non-negotiable. Deliverables I need from you: • Provision and harden the server (Docker + Linux) • Integrate Twilio (SMS, Voice, A2P) and WhatsApp so messages flow both ways • Hook in OpenAI / Claude endpoints for real-time responses • Implement logging, monitoring, and basic alerting • Provide concise API docs and a hand-off walkthrough Timeline: start this week, show tangible progress fast. To be considered, send over your direct experience, links to similar builds, your hourly or project rate, and a clear statement that you—not a proxy—will be doing the work. I’m hiring ASAP, so if you’re the kind of engineer who executes first and talks later, let’s move.

I can take this end to end—server hardening, Dockerized deployment, Twilio (SMS/Voice/A2P), WhatsApp Business API, and tight integration with OpenAI/Claude. I’ve built similar high-volume messaging layers before, and the priorities here are clear: strict security, predictable throughput, clean API design, and real monitoring instead of afterthought logs. I’ll provision the Linux stack, wire both channels with proper auth/rate-limits, implement fast LLM response flows, and deliver clear API docs plus a full hand-off. You’ll see progress in the first week. I do all the work myself—no proxies, no intermediaries. Ready to discuss scope and budget.

I’m an experienced backend engineer specializing in high-availability messaging platforms and LLM integration, and I’ll be the one doing 100% of the work—no agencies, no intermediaries. Relevant experience: 1) Designed and deployed a Dockerized microservice stack on Linux (Ubuntu + Docker Compose/Kubernetes) for a telecom client handling ~2M+ SMS/day. 2) Built Twilio-based messaging gateways (SMS, Voice, A2P) with webhooks, status callbacks, and delivery analytics; implemented per-customer rate limiting and IP whitelisting. Implemented WhatsApp Business API integrations (on-prem & cloud providers) for session/template messaging, fallbacks, and HSM template orchestration. 3) Integrated OpenAI and Claude for real-time conversational flows, including function calling, streaming responses, and guardrail layers. 4) Set up centralized logging (ELK/EFK, Loki/Grafana), metrics (Prometheus), and alerting (Alertmanager/PagerDuty) with security best practices (mTLS, JWT, rotated secrets, CIS hardening). What you’ll get: 1) Hardened Docker/Linux infra 2) Unified, well-documented REST API (auth, rate limiting, logging, retries) 3) End-to-end Twilio + WhatsApp + LLM wiring 4) Basic dashboards and alerting 5) Live hand-off walkthrough + concise docs Happy to work hourly or fixed-fee once scope is finalized. Ready to start this week and ship visible progress in the first few days.
