Full-Stack Architect | Hands-on Engineering Leader | Builder of Production Systems

I help founders and product teams build scalable, production-ready systems without painful rewrites later.

With 13+ years of experience, I design and implement transaction-heavy web applications that power real businesses — not demos or throwaway MVPs. I’ve led frontend and backend teams, owned system architecture end-to-end, and written the core services that scale.

Despite senior titles, I stay close to the code.

• Design scalable system architectures (monoliths, modular monoliths, microservices)
• Build transaction-heavy backends with clean domain models
• Lead teams while remaining deeply hands-on
• Review PRs with a focus on maintainability, testing, and long-term scalability
• Help startups avoid early technical decisions that cause rewrites later

• Frontend Lead — Rakuten Japan
  Worked on high-traffic consumer-facing systems used at massive scale

• Technical Lead — BJIT
  Delivered enterprise-grade software with strong engineering standards

• Lead Engineer at Cosmos Tech Labs
  Owned architecture, hiring, delivery, and long-term technical vision

• Node.js, TypeScript
• Java / Spring (enterprise systems)
• REST, GraphQL
• Event-driven & async systems
• PostgreSQL, MySQL, Redis
• Message queues & background processing

• React, Next.js
• TypeScript
• Scalable component architectures
• Performance optimization for large apps

• Solidity
• Foundry
• Openzepplin
• Wagmi, Metamask, Solflare
• Solana and EVM chain

• Domain-Driven Design (DDD)
• Clean Architecture
• Modular monoliths & microservices
• CI/CD pipelines
• Automated testing (unit, integration)
• Code reviews & engineering standards

• I design before I code
• I write the critical paths myself
• I optimize for clarity over cleverness
• I believe good architecture should:
  • Scale with the business
  • Be easy for new engineers to understand
  • Reduce future rewrites, not cause them

• Consulting with founders & early-stage startups
• Architecting complex systems
• Technical leadership roles
• Reviewing or rescuing existing codebases
