The founder needed a working product, not a frontend department.

The new psychology-education platform started without a frontend codebase. It needed a public course marketplace, learner profiles and progress, practice booking, instructor operations, secure educational media, and a reliable path to production.

I owned the frontend end to end: system shape, product implementation, API orchestration, validation, delivery infrastructure, deployment, and the migration of existing content.

Operating constraint
Move from zero to real learners quickly without producing a disposable prototype.
My ownership
All frontend product surfaces, Next.js BFF, CI/CD, Docker deployment, and legacy migration.
Primary users
Prospective learners, enrolled students, instructors, and product administrators.
Launch target
A maintainable production MVP with real content and operational workflows.

Product scope, delivery infrastructure, and migration arrived together.

The product could not launch as a set of disconnected screens. Booking had to create the right call links, permissions had to protect paid media, instructor tooling had to support daily operations, and existing content had to arrive from a service with no API.

Starting point
An empty frontend repository and a backend/CMS surface that needed product-facing orchestration.
Legacy data
The previous service exposed no API suitable for content migration.
Media
Video, audio, PDF, and document content required secure delivery from AWS S3.
Operations
Instructors needed schedules, session management, and learning-progress visualization.

A small architecture with explicit boundaries around external complexity.

The frontend was organized around product workflows, with a BFF layer absorbing API orchestration and infrastructure details that did not belong in page components.

01 · Product surface

Build learner and instructor workflows as one product system.

Delivered the marketplace, profiles, progress, practice booking, schedule management, and instructor progress views on shared domain rules.

02 · API boundary

Use a Next.js BFF for orchestration and stable client contracts.

Kept backend composition, validation, and integration-specific behavior behind a server boundary instead of spreading it through UI code.

03 · Content delivery

Keep access control attached to media delivery.

Implemented secure viewing for video, audio, PDFs, and documents stored in S3, with product permissions governing access.

04 · Migration

Automate extraction when no migration API exists.

Used Playwright-based scraping to move existing courses and content without manual re-entry, then put deployment behind GitLab CI/CD and Docker.

A production MVP that covered both customer experience and daily operations.

The first release was not only a marketing shell. Learners could discover courses, manage their learning, book practice, and consume protected content; instructors could operate schedules and follow progress; the team had a repeatable route to deployment.

Scope note. The delivery window refers to the first production MVP inside a seven-month engagement. This public case focuses on the frontend scope I owned and omits private customer and operational data.

One frontend owner, from product behavior to the deployment path.

Working solo meant keeping architectural ambition proportional to the team while still protecting the parts most likely to become expensive: product boundaries, API contracts, validation, access control, automated delivery, and migration repeatability.

Learner product
Course discovery, profiles, progress, booking, schedules, and protected educational content.
Instructor product
Session management, schedule workflows, and progress visualization with Recharts.
Delivery
GitLab CI/CD and Docker-based deployment created from scratch for the new frontend.
