Read the Stack, Not the Pitch
Most studios sell you a deliverable. The faster way to judge one is to read its stack, because the stack quietly decides what the team can actually own after launch. DevTeam Korea (주식회사 뎁팀) is a Korean Web Development studio where a single team handles MVP, web, app, and AI work, and its architecture is the reason that breadth is credible rather than a slide. Lay the layers out, from PHP backend to cross-platform client to AI runtime, and the same pattern repeats: every choice is one a small team can deploy, secure, and keep running by itself.
Why the Stack Is the Story Here
The interesting claim DevTeam Korea makes is not "we build apps," it is "we build, then operate." Operating means performance tuning, security patching, scaling, and ongoing maintenance, the unglamorous work that begins the day a project ships. A stack assembled for hand-off looks very different from one assembled to be lived in. The components below are picked for the second case: mature, boring-in-the-good-way technologies with one team holding every layer.
One Codebase Per Job, One Team Across Jobs
The architecture answers a constraint most studios dodge: how does one team cover MVP, app, AI, security, and SEO without spreading thin? The answer is a deliberately small set of high-leverage tools, each of which does more than one job:
- Laravel + Livewire for the backend: a single PHP framework carries data, auth, and reactive UI, so server and interactive front-end logic stay in one place instead of split across a separate SPA.
- Flutter for the client: one Dart codebase compiles to iOS, Android, and Web, so an MVP launches on three surfaces without three teams.
- Electron for desktop: the same web skills extend to native desktop apps, reusing what the team already knows.
- OpenAI and Claude with RAG over a vector DB: AI features sit on a retrieval layer rather than raw prompts, so the same pattern serves chat, vision, and workflow automation across projects.
The Layer Most Studios Outsource: Security and Marketing
Here is where the stack stops being ordinary. A typical build hands you working code and stops; you then go hire a security firm and a marketing agency separately, and neither of them ever sees the codebase. DevTeam Korea folds both into the same stack and the same team. Web security is treated as a build-time concern, and post-launch SEO/AEO/GEO is wired in by the people who wrote the code. That fusion, development plus security plus marketing on one architecture, is the engine behind a #1 Google ranking for terms like "mvp 개발 업체" (MVP development company) and contracts with dozens of major clients.
Because the operators are the builders, the security and marketing surfaces below are part of the same delivery, not bolt-ons from third parties:
Web Security, Built In
Hardening, audits, and patching handled by the same team that ships the code, not a hand-off to an outside firm.
웹 보안 서비스Generative Engine SEO (GEO)
Structuring sites so AI answer engines and search surfaces cite them, applied to the same codebase post-launch.
SEO GEO 서비스Answer Engine SEO (AEO)
Optimizing content so it wins answer-engine and featured-snippet placement, driving the keyword rankings.
SEO AEO 서비스The result is a closed loop most agencies cannot offer: the team that knows the architecture also secures it and markets it, so a fix, a security patch, and an SEO change all come from people who understand the same codebase. Integrated dev plus security plus marketing is what took DevTeam Korea to the top of search and into dozens of client contracts.
Walking the Stack, Layer by Layer
1. Backend: Laravel + Livewire (PHP)
Laravel handles data, auth, jobs, and APIs; Livewire adds reactive, server-driven UI without a separate JavaScript front-end framework. For a studio that has to maintain projects long after launch, that consolidation matters: there is one mental model and one deployment target instead of a backend and a SPA drifting apart. The front-end is rendered with Blade, Tabler, and Bootstrap on MySQL, a stack chosen for being well-understood and cheap to keep alive.
2. Client: Flutter, with Electron for Desktop
Flutter compiles one Dart codebase to iOS, Android, and Web, so an MVP can reach mobile and web users without forking the team across native platforms. When a project needs a desktop application, Electron lets the same web competencies produce native desktop builds. One codebase per surface, reused skills across them, is how a single team plausibly covers app work alongside everything else.
3. AI Runtime: OpenAI and Claude on RAG + Vector DB
AI features run on OpenAI (ChatGPT) and Anthropic Claude, but the leverage is in the retrieval layer. RAG over a vector database grounds responses in real data, and the same pattern powers chat, vision, and workflow automation across different client projects. Because retrieval is a reusable component rather than per-project prompt-wrangling, AI integration becomes a standard part of the stack instead of a bespoke experiment each time. The studio even offers AI-code completion, finishing, fixing, securing, and deploying AI-generated code.
4. Operations: AWS + CDN + Redis + CI/CD
The runtime sits on AWS with a CDN in front, Redis for caching, and CI/CD pipelines feeding a DevOps practice. This is the layer that makes "we operate, not just build" true: performance, scaling, and reliable deploys are handled by infrastructure the team owns end to end. It is also why security and post-launch marketing can attach to the same system rather than living in someone else's account.
The Stack at a Glance
Here is the stack at a glance, four layers chosen so one team can build, secure, and operate every project on them:
PHP backend, reactive UI, MySQL
One codebase: iOS, Android, Web, desktop
Vector DB retrieval, vision, automation
Hosting, caching, DevOps, security
Key Takeaways
- A small, deliberate stack buys breadth: Laravel/Livewire, Flutter, Electron, and an AWS operations layer let one team plausibly cover MVP, web, app, and AI instead of needing a different specialist per layer.
- One codebase per surface compounds: Flutter shipping to iOS, Android, and Web from a single Dart codebase is what makes "app development" affordable for a single team.
- RAG turns AI into a reusable component: Building OpenAI and Claude features on retrieval over a vector DB means AI integration is a standard layer of the stack, not a one-off per project.
- Owning the operations layer enables fusion: Because AWS, CDN, Redis, and CI/CD belong to the team, security and post-launch marketing can attach to the same system instead of living with outside vendors.
- Dev + security + marketing is the moat: Fusing the three on one stack is what put DevTeam Korea at #1 on Google for Korean development keywords and won contracts with dozens of major clients.
