01 / Enterprise Scope

Systems for real operators, not toy demos.

Insurance operations, restaurant POS, retail stores, fleet compliance, and infrastructure review workflows all show the same pattern: business-critical interfaces backed by serious platform work.

02 / Architecture Range

Frontend taste, backend depth, cloud discipline.

React and TypeScript experiences connect to Node, Go, FastAPI, Redis, BigQuery, Docker, Kubernetes, GCP, AWS, SSO, and CI/CD systems.

03 / Team Leverage

The work compounds through teams.

Mentoring, reviews, prototypes, production debugging, and cross-functional delivery make the portfolio read like a senior engineer's operating system, not a gallery.

About

A senior engineer who can cross the whole system.

I work across product, frontend, backend, cloud, and AI systems. My strongest projects sit where teams need someone who can understand the business problem, shape the architecture, build the experience, debug production behavior, and keep the delivery moving.

Recent work includes AI-powered insurance dashboards for Prudential Singapore, POS modernization across 200+ retail stores in Japan, enterprise RAG pipelines, fleet compliance workflows, and interactive map, 360-degree, and annotation tooling for infrastructure teams.

01 Full-stack delivery

React, Next.js, Node.js, TypeScript, Go, FastAPI, REST APIs, and production UI systems.

02 AI / LLM systems

LangChain, RAG, vector databases, fine-tuning workflows, Hugging Face, and AI-assisted tooling.

03 Cloud and platform

Docker, Kubernetes, GCP, AWS, BigQuery, Redis, CI/CD, observability, and release discipline.

04 Team leverage

Code reviews, pairing, mentoring, technical scoping, client-facing prototypes, and incident response.

Impact timeline

Proof that holds up after the first impression.

Each role adds a different layer: enterprise modernization, AI systems, platform engineering, and delivery leadership.
