Deep Dives for Freelancers & Solo Devs
Moving from tutorials to real-world projects requires a deeper understanding of technical documentation. These deep dives cover the practical skills needed to design robust systems.
1. Data Modeling & ERDs in Practice
How to translate business requirements into a relational database schema. Stop guessing and start designing tables, relationships (1:N, N:M), and indexes before writing SQL.
2. API Contract Design
How to write API specs (RESTful or GraphQL) that frontend and backend developers can agree on. Learn to define request payloads, response schemas, and error codes explicitly.
3. System Architecture for Startups
Real-world architecture patterns. Understand when a simple Monolith (Next.js + Postgres) is enough, and when you actually need Microservices or Serverless components.
4. Communicating Tech to Clients
For freelancers: How to write Technical Specs that non-technical clients can understand, protecting yourself from scope creep while building trust.
