I'm a software engineer with 9+ years of professional experience building modern web applications.

My strongest background is in React, Next.js, TypeScript, frontend architecture, and performance. Over the last few years, I've expanded further into full-stack engineering with Node.js, PostgreSQL, Redis, APIs, authentication, background jobs, and application architecture.

I also have 4 years of production Web3 experience, working across multiple EVM networks and Solana on wallet-connected applications, NFT marketplace flows, account linking, smart contract interactions, and transaction synchronization.

Outside professional work, I use Eastbase Studio as a personal engineering lab for end-to-end product development, architecture experiments, and AI-assisted workflows.

🧪 Featured Engineering Work

These public repositories are engineering labs and learning/reference projects unless explicitly marked otherwise. They are not client production source code.

⛓️ Web3 Marketplace

A modern Web3 application lab focused on wallet-connected product architecture, marketplace flows, multi-chain concerns, and production-style integration patterns.

Focus: EVM · Solana · Wallet Auth · Marketplace · Wagmi/Viem

💳 Payments & Fintech Architecture

fintech · fintech-microservices

Production-oriented payment architecture exploring idempotency, durable transaction boundaries, outbox processing, webhooks, asynchronous workers, and service decomposition.

Focus: Node.js · PostgreSQL · Redis · Queues · Payments

🛍️ Shopify Commerce Lab

shopify · shopify-storefront

A pair of projects exploring a production-style Shopify backend-for-frontend and storefront architecture, including commerce data flows, caching, and React storefront patterns.

Focus: Shopify · React · BFF · Storefront · Caching

📡 StackPulse

A live nonprofit product built and operated end-to-end. Technically simple by design, but useful as a real-world example of shipping, deployment, monitoring, iteration, and operating a product with meaningful daily usage.

Focus: Product Delivery · Operations · Monitoring · Production

🚀 Eastbase Studio — Personal Engineering Lab

Eastbase Studio is a personal product and engineering lab, separate from my professional roles.

I use it to experiment with shipping end-to-end SaaS products, AI features, product workflows, infrastructure choices, and developer tooling.

🧭 How I Work

Engineering

Start from system behavior and failure modes, not only implementation
Keep architecture proportional to the product and scale
Care deeply about frontend performance and interaction quality
Design APIs, async flows, caching, and state transitions explicitly
Prefer observable, reviewable production systems

Product & Delivery

Translate requirements into clear technical boundaries
Work comfortably in existing codebases and incremental migrations
Ship end-to-end features instead of optimizing only one layer
Use AI tools to accelerate research, implementation, review, and testing
Keep final engineering decisions under human ownership

🤝 Let's Connect

Senior engineering, strong frontend craft, full-stack ownership, and production Web3 experience.
