I am a Full Stack Engineer & SRE based in Tokyo with a passion for clean architecture and optimizing workflows & performance.

• By morning, I am my own personal barista, pulling the perfect manual espresso shot.
• By day, I modernize and re-architect legacy ancient artifacts written in COBOL/.NET/J2EE/Django to modern cloud-native frameworks like Java SpringBoot or Python FastAPI.
• By night, I hunt down latency bottlenecks, delete digits from company cloud bills, and optimize CI pipelines for developer efficiency.
• On my free time, I play cozy farming games like Stardew Valley, Harvest Moon, and Sakuna: Of Rice and Ruin.

"Fight for Software Architecture!" -- is written in my sticky notes desktop widget whether it's work or personal PC. Coding is an art that needs to be preserved.

The best compliment I received as someone passionate about software architecture is probably when my previous CTO said he had codegasms reading our codebase lol.

• Programming, duh:
  • Rearchitected fossilized codebases to modern ecosystems and frameworks.
  • Built an e-commerce backend from scratch to production.
• CI/CD Pipeline Optimization:
  • Enforced Sonarqube Quality Gate in CI pipeline throughout the whole organization (600+ repos).
  • Slashed pipeline build times from 1+ hours down to ~15 minutes by restructuring workflows to utilize multi-stage, multi-job parallelization, and advanced layer caching.
  • Revamped unstable Terraform and Gradle execution steps, driving the team's pipeline Pass Rate Trend from 30% to 80%.
• High-Scale Performance Tuning:
  • Slashed a flagship product's daily asset traffic from 35M to 500k requests, dropping load times from 25s to milliseconds.
  • Resolved a regional network bottleneck causing 2-minute latencies down to milliseconds using CDN caching.
  • Eliminated N+1 calls in our critical auth service— dropping daily calls from 500k to less than 50k.
• SRE Cost Killer:
  • At Medidata, I saved an estimated $105,000+ per month by optimizing log data tiers and pulling off telemetry migrations.

• Java Python TypeScript Ruby C# Cobol
• AWS Azure GCP Kubernetes Docker Terraform (IaC) GitHub Actions Azure Pipelines
• PostgreSQL Redis Elasticsearch Neo4j
• Grafana OpenTelemetry New Relic Sumo Logic

An open-source plugin I built and published for Spotify Backstage using TypeScript and React. It’s an automated, gamified tracker that continuously checks if repositories meet organizational engineering standards.

Migrated a legacy Django setup over to a sleek FastAPI architecture using Tortoise ORM, complete with automated Pytest pipelines, strict linting, and Stripe subscription billing.

Acted as a solo independent contractor to design and deliver an end-to-end data platform for a local government unit in the Philippines. It streamlined their regional report generation so well it won formal recognition.

• 🏂 Snowboarding: I ride goofy stance and love practicing Guratori (ground tricks) and carving in the Japanese Alps.
• ☕ Coffee Profile: Big fan of manual grinding, portable espresso gear, and roasting technicalities.
• 🎮 Cozy Gaming: I love unwinding by playing games like Stardew Valley, Harvest Moon, and Sakuna: Of Rice and Ruin. Who knows maybe I'll be a farmer when I'm older.
