Background

About Me

I'm a full-stack engineer with 10+ years building web applications end-to-end—from the interface a user touches down to the APIs, data models, and infrastructure underneath.

I work primarily in the modern TypeScript ecosystem (React, Next.js, Node.js), with Python services and AWS for infrastructure. Across 50+ projects, I've owned the full lifecycle—design, build, test, ship, and maintain—and mentored junior developers along the way.

What I care about most is software that stays reliable as it grows. I lean toward simple, maintainable solutions over clever ones, measure before I optimize, and treat security and testing as part of the work rather than an afterthought.

Engineering Philosophy

Systems Thinking:Design for maintainability and scale
Performance First:Measure everything, optimize with data
Code Quality:Clean, testable, well-documented
Product Mindset:Ask "why" before "how"

Areas of Expertise

Frontend Architecture

React, Next.js, TypeScript. Building performant, accessible interfaces that scale.

Backend Systems

Node.js, Python, Go. APIs, microservices, and distributed systems.

Data & Storage

PostgreSQL, MongoDB, Redis. Optimized queries and intelligent caching.

Cloud & DevOps

AWS, Docker, Kubernetes. Infrastructure as code and CI/CD pipelines.

Performance

Sub-100ms latency. Bundle optimization. Core Web Vitals excellence.

Quality & Security

Selected Work

Featured Work

Flagship builds and reference architectures — selected to show how I approach systems, not just ship features.

Flagship

Northstar Platform

Service-marketplace backend, built to production standards

Backend

Production-Grade Build

A service-marketplace backend I built end-to-end and open-sourced: multi-role authorization, background job processing, and a fully tested API. The code is public — it is the evidence.

Architecture & decisions

JWT + RBAC across 4 roles, enforced at the guard layer
Async work (notifications, payouts) offloaded to BullMQ + Redis
Prisma schema with explicit transaction boundaries
28+ tests covering auth, workflows, and edge cases

Coaching & performance platform from real domain experience

Fitness

In Development

A coaching platform shaped by my own years in fitness coaching. Architecture is complete and implementation is in progress — included to show domain-driven design, not a finished product.

Real-time collaboration — a reference architecture

SaaS

Reference Architecture

How I would design presence, sync, and conflict handling for distributed teams. A design study, not a deployed product — the value is in the tradeoffs.

Architecture & decisions

WebSocket presence with CRDT-style conflict resolution
Horizontal scaling via stateless gateways + Redis pub/sub
Tradeoff: consistency vs. latency for live editing

Systems Design Exercise

A systems-design exercise: structuring a low-latency trading and risk platform with ML in the loop. Focused on data flow and failure modes, not on a live trading desk.

Reference Architecture

A reference architecture for a privacy-conscious telemedicine platform, with auth, audit, and data isolation treated as first-class concerns from the start.

Systems Design Exercise

A systems-design exercise in zero-knowledge architecture: what it takes for a server to store secrets it can never read. The threat model came before the data model.

Architecture & decisions

Client-side encryption; server stores only ciphertext
Key hierarchy with envelope encryption (KMS)
Threat model written before any schema

Along the way
Technical Support & Client-Facing Work
Troubleshooting under pressure, translating between people and machines, and learning that clear communication is half the job.
Now
Software Engineering
Focused on systems, architecture, and scalable full-stack applications — building things that hold up in production.

Mindset

What Coaching Taught Me About Engineering

Feedback loops matter.

Tight loops — tests, monitoring, code review — catch problems while they’re still cheap to fix.

Consistency beats intensity.

Steady, incremental delivery and small commits beat heroic rewrites. Compounding works in code too.

Systems outperform motivation.

Good defaults, automation, and CI remove reliance on willpower. The system should make the right thing easy.

Communication is a technical skill.

Clear docs, naming, and PR descriptions are part of the engineering — not a soft extra.

Off the Clock

Beyond Software

Fitness & Kickboxing

Years of training and coaching. The discipline of showing up and improving by small margins carries directly into how I work.

Human Performance

I think in feedback loops, recovery, and sustainable load — for people and for systems. Both fail the same way when you ignore the fundamentals.

Continuous Learning

New frameworks, certifications, and ideas, constantly. Curiosity is the habit; staying current is the result.
