# Vo Chinh — Senior Frontend Engineer

> Senior Frontend Engineer — composable commerce, performance, AI-assisted delivery
> Six years building production frontends. The last four on headless commerce for German enterprise clients.
> Location: Da Nang, Vietnam | Availability: Remote preferred (EU/APAC overlap), Open to relocation (with sponsorship)

## Key Metrics & Proofs
- **Production frontends:** 6+ years
- **German enterprise clients:** 4+ years
- **Commerce:** commercetools · Shopware · Shopify
- **Certifications:** AWS Certified Dev · TOEIC 820

## 01 / CORE ARCHITECTURE PILLARS
### Composable commerce frontends
I build storefronts against headless commerce backends — commercetools with Frontastic, Shopware, Shopify. SSR with Next.js, componentised catalogue and checkout surfaces, and the integration work between the frontend and whatever the client's commerce, PIM, and ERP stack already is.

### Performance and testing as delivery, not cleanup
Cypress and Vitest coverage written alongside features rather than after them, focused on the critical flows. Performance treated as a budget the build enforces, not a report someone reads later. On a client storefront I raised the Lighthouse performance score from around 60 to around 80 through image and JavaScript optimization.

### AI-assisted delivery, verified
I build agentic workflows that take a ticket end to end — parse it, investigate the code, implement, run a verify loop, generate the tests. My job shifted from writing to reviewing. The output is always checked; it is never trusted blindly.

## 02 / HOW I WORK — REVIEW-FIRST
The agentic workflows I build produce code faster than I could write it. That only helps if the review step is real, so the loop is designed around verification: every change runs against tests before I see it, and I read the diff as if a stranger wrote it.

This is the part people get wrong about AI-assisted engineering. The speedup is not in typing. It is in being able to spend the same hours on logic and edge cases instead of boilerplate, documentation, and test scaffolding.

I work asynchronously across Vietnam and EU timezones, which forces the same discipline: written decisions, small reviewable changes, and documentation that exists because it was generated as part of delivery rather than promised for later.

## Architectural Case Studies
### Agentic delivery workflow (SHOPMACHER eCommerce GmbH & Co. KG)
- **Role:** Frontend / AI Integration Developer
- **Context:** Agency delivery, distributed team, steady ticket flow across multiple commerce projects.
- **Problem:** A large share of each ticket was mechanical — locating the right code, writing the test scaffold, updating documentation. High effort, low judgement, and the parts most likely to be skipped under deadline.
- **Approach:** Reusable Claude Code skills that take a ticket end to end: parse the ticket, investigate the relevant code, implement, run a verify loop against tests, generate automation tests and technical documentation. Designed review-first — the human step is reading the diff, not producing it. I built and shared these skills, and 4-5 engineers on my team now run them.
- **Impact:** The workflow runs on nearly every ticket I am assigned. It collapses the investigation step: on a typical ticket, understanding the existing code and business logic used to take about an hour and now takes about half that. The time saved concentrates where judgement is lowest — documentation, test authoring, and investigation. Coverage and delivery-time percentages are not claimed, because they cannot be defended precisely.
- **Stack:** Claude Code, TypeScript, Cypress, Vitest
- **What I would do differently:** Initially I tried to automate too much of the PR description and code review comments in one shot. That generated noise that reviewers ignored. Stripping the automation down to purely verified implementation, test scaffolding, and factual doc generation made adoption immediate across the team.

### Composable storefront, ANWR (ANWR Group (via SHOPMACHER))
- **Role:** Senior Frontend Engineer
- **Context:** Headless B2B and B2C storefront work for ANWR, a German footwear and sportswear retail group, across three storefronts: sport2000, schuhe.de, and ATS.
- **Problem:** The hard part was integration — a single Next.js frontend on commercetools via Frontastic, wired into the surrounding commerce, PIM, and backend systems, and kept consistent across three storefronts.
- **Approach:** Next.js with SSR against commercetools via Frontastic. Built nearly all storefront features, including Algolia search implemented from scratch across PLP and PDP — with caching and search latency and relevance tuning — and work on the checkout surface. Cypress coverage for the critical flows, code review, and backlog refinement directly with product owners.
- **Impact:** Raised the storefront's Lighthouse performance score from around 60 to around 80 through image and JavaScript optimization. Business metrics such as catalogue size, traffic, and order volume are withheld under NDA.
- **Stack:** Next.js, TypeScript, Tailwind CSS, commercetools, Frontastic, Algolia, Cypress

### Pharmacy B2B CRM platform (NFQ Vietnam)
- **Role:** Middle Front-end Developer
- **Context:** Customer-engagement platform for the pharmacy industry at NFQ Vietnam (Mar 2022 – Mar 2023). Outsourcing for a small German team.
- **Problem:** Complex data-heavy healthcare interfaces needing reliable state management across GraphQL and REST APIs.
- **Approach:** React, TypeScript, GraphQL (primary), REST, MaterialUI. Collaborated with UX/UI designers; root cause analysis, code review, and unit testing alongside senior engineers; Scrum delivery.
- **Impact:** Delivered robust customer-engagement features with unit + E2E testing (Cypress).
- **Stack:** React, TypeScript, GraphQL, REST, MaterialUI, Cypress

### BL Education course platform (Enlab Software)
- **Role:** Senior Front-end Developer
- **Context:** Online course platform, client-facing app plus admin (browse, purchase, and learn courses) at Enlab Software (Mar 2021 – Mar 2022).
- **Problem:** Greenfield build with no existing frontend conventions and a team of 5-6 frontend engineers.
- **Approach:** Led a frontend team of 5-6: owned the FE build, project template, conventions, and technical documentation; trained interns; worked with clients, UX, and PMs. Vue 2, Nuxt, Tailwind CSS, ElementUI, NestJS, PostgreSQL, Azure, TypeScript.
- **Impact:** Built from scratch, set conventions and documentation for a 5-6 person frontend team, and earned the Rising Star award for outstanding competence and contribution.
- **Stack:** Vue 2, Nuxt, Tailwind CSS, ElementUI, NestJS, PostgreSQL, Azure, TypeScript
