1Fullstack showcase project

01 / Overview

Build on strength. Close the gaps.

Objective

Prepare for a fullstack role by strengthening timed coding, backend and database skills, and system design while drawing on 14+ years of frontend and iOS delivery experience.

Existing strengths
  • Frontend architecture and delivery
  • React, TypeScript, iOS, and some Node.js
  • AWS CI/CD and ECS deployment
Development priorities
  • Timed algorithms and live coding
  • Backend and relational database depth
  • Server-side system design

02 / Roadmap

Four weeks, clear checkpoints.

Each week adds a practical capability and ends with an interview-style milestone.

01

Establish the baseline

Refresh algorithm fundamentals, Node.js, and SQL.

Planned milestoneComplete a 45-minute mock interview
02

Build backend depth

Work through REST, authentication, and database design.

Planned milestoneDeliver CRUD endpoints backed by a real database
03

Connect the system

Integrate the fullstack project and practice system design.

Planned milestoneComplete a coding mock and recorded design walkthrough
04

Simulate the interview

Run timed mocks and polish technical and leadership narratives.

Planned milestoneComplete a full simulated interview loop

03 / Time allocation

Focus where it matters.

The largest share goes to coding and backend fundamentals, with dedicated time for technical questions and system design.

Algorithms and live coding35%
Backend and databases35%
Frontend technical questions and system design30%

04 / Planned deliverables

Tangible evidence of readiness.

Outputs are designed to support stronger interview performance and a concrete fullstack story.

01 / CODING

40 algorithm problems with a reviewed error log

02 / BUILD

One deployed fullstack showcase project with React/TypeScript, REST API, PostgreSQL, authentication, and tests

03 / DESIGN

Two practiced system designs

04 / SIMULATION

Weekly mock interviews, culminating in a full interview-day simulation
