From Vibe Coder to Software Engineer: Part 2: Building (Days 11–20) - A 30-Day Guide to Full-Stack Development, APIs, and Databases

Take your software from a simple prototype to a high-availability, production-grade application!

In Part 2: Building (Days 11–20) of the From Vibe Coder to Software Engineer series, follow Leo as he tackles full-stack architecture, relational database design, API protocols, and production security compliance under the mentorship of Staff Engineer Sarah.

Building real-world software requires more than generated code snippets—it demands scalable databases, resilient APIs, and enterprise security. Part 2 bridges the gap between frontend interfaces and backend infrastructure through 10 custom blueprint infographics, practical code walkthroughs, and real-world tech disaster analysis.

• Day 11: UI/UX & Design Systems — 8px spatial grid systems, design tokens, and accessibility contrast standards.
• Day 12: SDLC & Requirements Engineering — PRD specs, sequence diagrams, and user story mapping.
• Day 13: System Design & High Availability — Load balancing, horizontal scaling, and multi-node Redis caching.
• Day 14: SQL Relational Databases — B-Tree indexing, ACID transactions, and avoiding unindexed table scans.
• Day 15: NoSQL & Vector RAG Pipelines — Document databases, vector embeddings, and RAG architectures.
• Day 16: High-Performance Backend — Event-driven Node.js and FastAPI async coroutines.
• Day 17: API Protocol Architecture — REST vs GraphQL vs gRPC binary serialization.
• Day 18: Authentication & OAuth2 — JWT token rotation, HTTP-Only cookies, and RBAC authorization.
• Day 19: OWASP Top 10 Security — Preventing SQL Injection, XSS, and CSRF attacks.
• Day 20: Supply Chain Security & SBOM — Dependency audits, SBOM manifests, and zero-trust pipelines.

Features real-world production incident case studies, including the 2017 GitLab primary database loss and the 2017 Equifax data breach.
