Full-Stack DevOps Engineer

Job Description Project Overview We have a fully code-complete Micro-SaaS platform called BounceBack SMS. The app is an automated missed-call text-back and lead recovery system built using Next.js 15, Tailwind CSS, Twilio API, and Supabase. The repository is isolated, structured, and securely hosted in a private GitHub repository. We are looking for an experienced Full-Stack/DevOps Engineer to handle the production deployment, configure live API pipelines, manage database environment mapping, and ensure the entire setup runs on a frictionless, automated continuous integration/continuous deployment (CI/CD) framework. Scope of Work (Key Deliverables) 1. Infrastructure Mapping & Production Deployment Deploy the Next.js 15 frontend/backend application from our private GitHub repository to production hosting (Vercel/Render). Map and connect production environment variables, database schemas, and connection strings to our live database instance (Supabase/PostgreSQL). Configure a permanent automated CI/CD pipeline (e.g., GitHub Actions or Vercel integration) ensuring any future push to the ⁠main⁠ branch automatically rebuilds and deploys the app flawlessly. 2. Twilio API & A2P 10DLC Compliance Configuration Connect and secure our live Twilio API gateways within the backend architecture. Audit and verify that our messaging endpoints cleanly support incoming webhooks for missed-call detection. Crucial Milestone: Assist and audit our US A2P 10DLC Campaign Registration via Twilio to ensure 100% carrier delivery compliance (Privacy Policy and Terms pages are already live and coded in the repo). 3. Live Stripe Billing Integration Transition our checkout environment variables from Stripe Sandbox/Test Mode into Live Production Mode. Wire up our exact pricing architecture: $0 Setup Fee, 100 Free Leads Usage Trial, transitioning into a flat $19.99/Month Recurring Subscription. Ensure Stripe webhooks are completely listening to successfully provision, pause, or update customer account access tiers inside our database based on subscription state. 4. Handover & Bulletproof Documentation Provide a brief, plaintext ⁠.txt⁠ or ⁠.md⁠ technical handover file outlining the deployed environment structure, a list of active API webhooks, and step-by-step instructions for simple environment variable updates. Required Tech Stack Expertise Frameworks: Next.js 15 (App Router), React, Tailwind CSS Database: Supabase / PostgreSQL (Schema sync, migrations, security policies) APIs: Twilio SMS Gateway (Webhook architecture, A2P 10DLC registration compliance) Payment Rail: Stripe Billing API (Usage-based trials, recurring webhooks) DevOps/Version Control: Git, Private GitHub Repositories, Vercel/Render, CI/CD automation Preferred Qualifications Proven track record deploying independent Micro-SaaS or automation applications. Deep familiarity with strict US telecom carrier A2P SMS delivery guidelines to prevent messaging blocking or spam flags. Obsession with clean environment variable separation—absolutely no hardcoded credentials. Excellent technical communication skills and availability to run live end-to-end integration testing before final milestone sign-off. 🎯 Candidate Screening Questions (Include on Upwork) 1. Briefly describe your experience configuring Twilio webhooks and handling the US A2P 10DLC registration process to ensure high carrier delivery rates. 2. How would you configure Stripe to trigger a recurring $19.99/mo flat-rate subscription specifically after a user consumes exactly 100 free database actions/leads? 3. Confirm that you are comfortable working out of a private GitHub repository and setting up an automated CI/CD pipeline so I never have to manually pay for developer redeployments.
