Currently shipping → infrastructure platform · v3.2

Building cloud-native systems
that don't break at 3 AM.

I turn complex business problems into elegant, scalable systems — across modern JavaScript, cloud-native infrastructure, and the teams that ship them.

Selected work.

Three engagements where the architecture mattered. Click any row to expand the problem, approach, and outcomes.

01

Enterprise Collaboration Suite

Lead Architect · 2023 — Present

Market-disrupting collaboration platform with a 98% code-reusability rate between web and mobile. Engineered real-time WebSocket integration and held 99.99% uptime via AWS + Terraform.

ReactReact NativeWebSocketsAWSTerraform

Problem

Teams needed a single collaboration surface across web and mobile without forking codebases or accepting laggy real-time.

Approach

  • Single design-system + component layer rendered to RN and DOM
  • Sharded WebSocket fleet with backpressure-aware fan-out
  • Terraform modules for blue/green env replication across regions
  • Multi-region failover with regional state CRDTs

Outcomes

  • 98% shared code · 32% faster feature velocity
  • 99.99% measured uptime over 18 months
  • P95 message delivery: 84ms cross-region

Infrastructure Management Dashboard

Technical Lead · 2021 — 2023

Architected a Next.js-based UI that boosted SEO performance by 40% while managing data for 10,000+ daily active users with role-based access control.

Next.jsMongoDBRBACNode.js

Problem

Operators needed a fast, indexable dashboard that could expose sensitive infrastructure to the right people only.

Approach

  • Hybrid SSR/ISR for indexable shell, client islands for live data
  • Role-based access modeled as policy graph, evaluated edge-side
  • MongoDB schema sharded by tenant, with cold-tier compaction
  • Background API with queue-based ingest for 12M events/day

Outcomes

  • +40% SEO performance on Core Web Vitals
  • 10k+ daily active operators
  • Sub-100ms P50 dashboard render

Healthcare IoT Vital Monitor

Platform Architect · 2018 — 2019

Pioneered a HIPAA-compliant real-time monitoring system connecting medical hardware to mobile interfaces using Pulumi and React Native.

PulumiReact NativeBLENode.js

Problem

Bedside vitals devices needed to stream to mobile interfaces without violating HIPAA, on flaky hospital Wi-Fi.

Approach

  • BLE + LTE failover with on-device buffer-and-replay
  • End-to-end TLS with audit trail keyed to clinician sessions
  • Pulumi-managed HIPAA-eligible AWS env, fully reproducible
  • Alarm fatigue reduction via signal-quality scoring

Outcomes

  • 85% fewer deployment errors via Pulumi IaC
  • HIPAA audit passed first attempt
  • Sub-2s vitals latency end-to-end
