ABOUT THE PROJECTS. I run a curated marketplace on Shopify (The Ever Good) and I am building out an AI automation system to handle routine tasks in the business. I am AI-savvy and have built a Python agent myself, so I understand what I am asking for. I have the architecture planned and the business requirements semi-documented for each piece. I simply do not have the time to build everything I want to build, which is why I need a developer to work alongside me. The first project is a product review collection and import system. If it goes well, there is ongoing work building out additional agents over time, one at a time. This is a potential long-term engagement depending on how the first project goes. WHAT WE ARE BUILDING. The overall system is a set of AI agents that handle specific business tasks and route outputs to a simple dashboard where I can review, approve, and trigger actions before anything goes live. The dashboard is a Lovable build that gives me a single place to monitor agent status, review outputs, and approve or return anything that needs a human decision before it moves forward. Agents are planned across several areas of the business. We will build one at a time. I will walk you through the requirements for each before you start. Examples of agents here by business category (these could change): - MARKETPLACE & CATALOG. Product Reviews (first project), Catalog Enrichment and SEO, Pricing and Margin Monitor, New Product Auto-Pricer, Maker Stories, Maker Audit, Maker Analytics, Review Monitor. - CONTENT & SOCIAL. Content Generation, Cultural Moment Monitor, Social Publishing, Pinterest Curator, Instagram DM Automation, Image Production, Founder Content Amplifier. - MARKETING & ADS. Email Sequences, Paid Media Director, Ads Performance Monitor, LinkedIn Outreach. - SEO and Search. SEO and AI Search Visibility, Crawl Error and Redirects. - THE SCHOOL (Our Coaching Offerings). AI Readiness Assessment, Coaching Prep Tool, Workshop Launcher, Course Completion Monitor, Immersion Round Tracker. - FINANCE & OPS. Profit Police, Cash Flow Forecaster, Financial Health Monitor, System Health Monitor. - CUSTOMER SERVICE & GIFTING. Customer Service Drafts, Gift Inquiry and Proposals, Basket Assembler. OUR TECH STACK (Could Change). - AI AGENT BUILDING STACK. Claude Code, Claude API, Python, Make.com, Replit, Lovable, Google Sheets API, Baserow. - OTHER BUSINESS SYSTEMS. Shopify API, DropCommerce API, Matrixify, Typeform, Stripe API, Yotpo API, Klaviyo API, Instagram Business API, Later API, Pinterest API, ManyChat API, Bannerbear API, LinkedIn API, Google Analytics 4 API, Google Search Console API, DataForSEO API, QuickBooks Online API, Google Drive API.

About the Role We are a funded fintech startup building a first-of-its-kind platform at the intersection of digital banking and social media intelligence. Think credit scoring — but for creators and entrepreneurs. Our platform combines financial tools, OAuth-connected social data, and a proprietary scoring engine into a seamless product used by creators, small business owners, and entrepreneurs. We are looking for a Senior Full-Stack Developer to own our entire technical stack — from server infrastructure to front-end experience — and help us scale from beta into a full product launch. This is not a freelance gig. This is a full-time salaried role with real equity potential at an early-stage company that is actively raising its seed round. You will be the technical backbone of the company. You will work directly with the founding team. What You Will Be Working On A PHP/Laravel API backend serving a multi-app ecosystem across production, staging, and demo environments A vanilla JS + HTML/CSS front-end for a consumer-facing creator dashboard, public profile pages, and a verification system A proprietary scoring engine that processes consented, first-party OAuth data from platforms including X/Twitter, Instagram, TikTok, LinkedIn, and YouTube A digital banking portal for investor and user financial management (Mercury, Dwolla, Stripe integrations) A server infrastructure running on a dedicated Hetzner bare-metal server (Ubuntu 24, Plesk, Apache, MySQL, Redis) that you will own end to end An admin dashboard for internal team operations — user management, lending, capital, communications Upcoming work: CI/CD pipeline implementation, Redis migration to internal infrastructure, TikTok and Meta OAuth API wiring, mobile-responsive passes, and banking partner integration The Stack Backend: PHP 8.x / Laravel, MySQL, Redis Front-End: Vanilla JavaScript, HTML5, CSS3 (no framework — clean component-based architecture) Infrastructure: Ubuntu 24.04, Plesk Obsidian, Apache, Hetzner dedicated server Integrations: OAuth 2.0 (X, Instagram, TikTok, LinkedIn, YouTube), Dwolla, Mercury, Twilio, Firebase, Stripe, Shopify Version Control: GitHub (org-based, branch workflow) Other: QR code generation, real-time verification systems, social data normalization What We Are Looking For Must-haves: 5+ years of full-stack development experience Strong PHP/Laravel — you can read, debug, and architect Laravel apps without hand-holding Solid vanilla JavaScript — you do not need React or Vue to build clean, fast, interactive UIs Comfortable owning server infrastructure — SSH, Linux, Plesk or cPanel, Apache config, MySQL administration Experience with OAuth 2.0 integrations — connecting to social media platform APIs is second nature Familiarity with fintech concepts — payments, banking APIs, KYC/AML flows, or financial data handling Git workflow discipline — clean commits, branch management, no cowboy pushes to main Strong written communication — you document your work, you write clear commit messages, you can explain architecture decisions to non-technical stakeholders Strong pluses: Experience at a fintech startup or financial technology company Familiarity with social media platform developer programs (X API, Meta Graph API, TikTok for Developers) Experience setting up CI/CD pipelines (GitHub Actions, Forge, Envoyer, or similar) Experience with Redis configuration and migration Any background in credit scoring, data normalization, or analytics engine architecture Prior W-2 employment experience (this is not a 1099 contractor role) What You Get Full-time salaried position — compensation discussed during interview based on experience Direct access to and collaboration with the founding team The opportunity to be the lead technical voice at a company that is actively fundraising and preparing for a full public launch A codebase that is real, live, and in use — not a greenfield project, not a prototype Remote-first culture — flexible hours, async-friendly, results-driven What This Is Not This is not a short-term project or hourly contract This is not a role where you will be handed a spec and left alone This is not a company where the tech is an afterthought — the product IS the technology

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.

I am building an authentication library and a billing platform in Golang + Postgres. Auth-library is embedded only, while billing can be an embedded-library, and also a stand-alone application. The platform is intended to make it easy for Go-devs to write authentication (users register, OIDC, recover password, etc.), and manage billing their users (various billing providers in addition to Stripe, including crypto). These codebases are mostly written by AI (Claude Code and Codex) but the issue is that these tools suck. The write a lot of slop, and their systems don't work, and I don't trust them. With auth + billing, these are highly sensitive areas where we cannot afford to fuck up. Deliverables are: 1. a list of tasks the LLMs must do to refactor / fix these systems 2. a complete audit of all APIs (the surface areas / shapes that are used as system boundaries) 3. integration tests that will pass, if the LLM's code is correct 4. a complete security audit, to address any vulnerabilities / exploits possible I am only looking to hire someone in California / colorado. I want to work synchronously with them; for every hour you bill we'll be on a call together so that we can maximize communication bandwidth. I live in Denver, but I plan to move to SF soon. I'd be down to work together in person in the future, but for now we'll only be working synchronously-remotely. Human-written applications only. Template or LLM-written responses here will be rejected immediately. Please list your qualifications concisely. Don't say 'I am a Golang expert' say 'I worked at company X, and built system Y in Go which does Z.' Thanks for your time.
