Senior Full-Stack Engineer · Laravel, Go, React/TypeScript · AI-native dev with Claude Code

- Run a small software studio (album.ko-gap.com) and a web agency that builds one-page websites for small shops (mireebang.com). I take projects from a first demo through launch and ongoing support.
- Client work and demos: an employee evaluation system that replaces Excel and runs on closed networks (Next.js, TypeScript, Docker); a logistics company website with a transport inquiry system and admin back office (Spring Boot 3, Java 21, React); a VIN/part-number filter cross-reference tool (Next.js, Prisma).
- Building an online ichiban-kuji draw platform for a Kmong client, with simultaneous draws and payment gateway integration.
- Freelance contract with MSGlobal: building the company's internal works (groupware) system on Next.js, FastAPI and PostgreSQL as part of its AX (AI transformation) effort.
- R&D published on GitHub: FlowGL (dependency-free WebGL2 flowchart library) and Local LLM Proxy (Anthropic Messages API to llama.cpp/Ollama/LM Studio).

- Only engineer on a multi-strategy algorithmic trading system, working remotely for a Dubai-based firm. Built and ran both the backend and the ops dashboard.
- Wrote the OMS in Go. A state machine takes each signal through to fill, with queueing, throttling and retries around exchange rate limits and guards against duplicate or rapid-fire signals. Handled 100+ concurrent signals at P99 200ms, including on exchanges with no WebSocket API.
- Built the ops dashboard (Go/fasthttp + React/TypeScript): live uPnL, positions and order history over a WebSocket hub, plus a 1-minute snapshot worker that reconciles exchange REST data into the NAV/PnL pipeline.
- Set up monitoring on VictoriaMetrics + Grafana with 15+ custom metrics.
- Kept Claude Code output consistent with the spec on a long-running codebase: layered context docs, hooks that enforce project rules, an AI review loop, and MCP/Skills-based code search.

- The only IT person for a 30-50 person company across 4 departments: 4-5 systems (CRM, website, mobile app, internal tools) plus servers, network, accounts, security and backups.
- Built a new CRM while keeping the legacy one running. Set priorities from stakeholder interviews and took it from planning through deployment and support.
- Built new internal web services end to end, from requirements and UI to deployment.
- Pulled data that each department had kept separately into one place.

- Ran my own freelance business for about 10 months: 4 new builds and 2 maintenance contracts in Laravel and React. Handled clients, quotes, scheduling, development, QA, deployment and operations myself, usually for several clients at once.
- Took a 2-month frontend placement at an IT services firm and got productive on their existing codebase within the first weeks.

- Joined to lead the dev team as the company moved from client outsourcing work to its own products. Reworked process, stack and hiring.
- Led the move from HTML/jQuery to React: component structure, state management patterns, build setup, and getting the team onto React.
- Hired and onboarded junior developers and got them shipping real projects through code review and pair programming.
- Built B2B/B2C SaaS APIs in Laravel: REST endpoints, DB schema, auth/permissions, external integrations.
- Introduced Slack and Notion with channel, notification and doc conventions for async work.

- PM with a development background on several web/app projects, sitting between planning, design and development.
- Ran requirements, schedules and issue tracking, and explained technical constraints to the business and design teams.
- Handled iOS releases and native integrations: APNs push, StoreKit auto-renewing subscriptions with receipt validation and restore, and App Store review, without changing the existing payment structure.
- Also did iOS development with AVFoundation, Core Image and Metal.

- Sole developer at a surveying/engineering firm, building AutoCAD automation programs and libraries.
- Built a library that finds power-line wires in large 3D LiDAR point clouds and computes sag curves by curve fitting. It became part of the company's standard workflow and is now a registered patent.
- Built a program to manage all of the company's AutoLISP libraries in one place.
