Senior Developer to Optimize Real-Time SMS Platform (Twilio)

---

---

I’m looking for a senior developer to jump into Sprout SMS, a 2-way SMS platform I’ve built that integrates Twilio, Telnyx, and SignalWire—something my competitors (like textedly) don’t offer. My current dev has done a phenomenal job, but we need expert help to polish some critical areas ASAP. What You’ll Do: • Fix real-time inbox updates (e.g., instant refresh, mark read/unread, prioritize conversations on incoming calls). • Optimize broadcast campaigns so individual messages can send without delays during a broadcast. • Audit and tweak the backend for scalability and performance. Must-Haves: • 5+ years of experience with SMS/telephony APIs (Twilio, Telnyx, or SignalWire). • Proven skills in real-time systems (e.g., WebSockets, server-sent events, or efficient polling). • Strong backend chops (Node.js, Python, or similar—our stack is [insert your stack here]). • Experience with queueing systems (e.g., Redis, RabbitMQ) for broadcast optimization. Nice-to-Haves: • Worked on SMS platforms or SaaS like Avochato. • UI integration experience for seamless inbox updates.
