About Us

We're a digital marketing agency building internal analytics platforms for our clients, and we're hiring a Full-Stack Developer to join our in-house tech team.

We integrate Facebook Ads, Google Analytics and other marketing APIs into real-time

dashboards that help businesses make data-driven decisions.

You'll work directly with the COO to build features, fix bugs and optimize our growing

platform. We're small, practical and move fast - using AI tools to accelerate development

while maintaining code quality.

What You Will Be Doing

- Build and enhance React/TypeScript dashboard components with real-time data

- Integrate marketing APIs (Facebook Marketing API, Google Analytics, etc.)

- Integrate other external APIs

- Build modular functions that can be redeployed

- Write and deploy Supabase Edge Functions for data pipelines

- Design PostgreSQL schemas, views and optimize complex queries

- Debug data flow issues: API ? Database ? Frontend

- Handle API rate limits, pagination and error scenarios

- Use AI coding assistants (Claude, Cursor, lovable.dev) to accelerate development

- Translate business requirements into working features

- Ship quickly, iterate and maintain existing codebases

Required Skills

- Strong React, TypeScript and modern JavaScript fundamentals

- Experience with REST APIs, webhooks and third-party integrations

- Comfortable writing SQL and working with PostgreSQL/Supabase

- Understanding of database relationships, foreign keys and constraints

- Experience deploying serverless functions (Supabase Edge Functions or similar)

- Proficient with Git and can read/modify existing codebases

- Can work autonomously and communicate technical decisions clearly

- Uses AI tools effectively BUT can debug and problem-solve independently

- Comfortable with Tailwind CSS and shadcn/ui components

What We're NOT Looking For

- Developers who only copy-paste AI code without understanding it

- People who can't debug without AI assistance

- Candidates who only have greenfield project experience

You're a Great Fit If

- You can identify why a query returns a 400 error and fix it

- You understand database schema relationships intuitively

- You use AI to go faster, but can explain what the code does
