Job Description
Backend-heavy full-stack developer partnering with a design-first founder building custom service industry software solutions. Focus on backend architecture and integration of various third-party tools.
Responsibilities:
- Design and build backend infrastructure using Supabase, PostgreSQL, Auth, RLS, Storage, Realtime, and Edge Functions.
- Create clean database schemas with proper relationships, indexes, constraints, and migration planning.
- Write secure Row Level Security policies for user-facing tables.
- Set up authentication flows, permissions, sessions, and access logic where needed.
- Build TypeScript/Deno Edge Functions for business logic, webhooks, scheduled jobs, and API integrations.
- Integrate third-party tools such as Stripe, Twilio, OpenAI, SendGrid/Resend, Zapier/Make, or client-specific APIs.
- Connect React/Tailwind frontends to the backend and help bridge the handoff between UI and infrastructure.
- Review existing backend work and suggest improvements without overcomplicating the product.
- Help turn prototypes into stable, scalable, production-ready applications.
Requirements:
- 3–6+ years of experience building production full-stack or backend-heavy web applications
- Deep hands-on experience with Supabase, including real shipped apps using RLS, Edge Functions, and Auth
- Strong PostgreSQL fundamentals: schema design, indexes, query optimization, constraints, and ability to read an EXPLAIN plan
- TypeScript / Node / Deno competence for building backend logic and Edge Functions
- Strong security instincts: RLS, input validation, permissions, and secrets management should be part of your default approach
- Clear written and spoken English for async handoff, documentation, and weekly Google Meet syncs
- Self-directed working style: able to take a spec doc and prototype, move independently, and surface questions in batches
- Strong communication skills, including the ability to explain tradeoffs and push back constructively when a better technical path exists
- A portfolio, case study, clickable prototype, or live/repo link that shows how you think and build
- Experience with third-party API integrations such as Stripe, Twilio, OpenAI, SendGrid/Resend, Make/Zapier, or client-specific tools
- Comfort with React + Tailwind so you can help wire frontends to the backend
- Experience with service-industry tools, such as CRMs, scheduling systems, operations dashboards, intake forms, or field-service workflows
- A point of view on workflow and process design, including state flows, approval chains, dashboards, or operational logic
Benefits:
- Long-term, ongoing contractor relationship — not a one-off project
- Remote work, with LATAM timezone overlap preferred
- Flexible part-time setup: starting around a 20-hour monthly retainer, with potential to grow to 40–60 hours/month depending on fit and project flow
- High ownership and influence over technical direction
- Collaborative, low-bureaucracy environment
