Featured Case Studies

Real-world systems delivering measurable outcomes.

Production · Backend Engineering + Integrations

Multi-Tenant B2B SaaS Engine

Main backend developer on a production multi-tenant B2B gifting platform. Engineered a modular, extensible NestJS codebase covering multi-tenant isolation, product variation modeling, async SQS worker patterns, and integrations with Stripe, Shopify, Xero, and AWS S3.

Module

Per-domain NestJS structure: consistent across all feature areas

Guard

Layer tenant isolation — scoping enforced structurally, not by convention

About Me

I build systems today so you don't have to work as hard tomorrow.

My philosophy is simple: If I have to do it three times, I automate it.

I started my career as a software engineer, but I quickly realized that the biggest bottleneck in most businesses isn't the code — it's the manual "busy work" that slows teams down.

Now, I apply that engineering mindset to operations. I don't just patch problems; I build self-sustaining architectures (using n8n, Python, and AI) that make every future task faster, cheaper, and easier than the last.

Process

From Discovery to Production

A structured, transparent workflow designed to deliver reliability.

Discover

Understand your business processes, pain points, and revenue goals through a focused strategy session.

Architect

Design integration maps, data flows, and system architecture in collaboration with stakeholders before implementation.

Build

Develop the solution iteratively with clean code, proper error handling, and comprehensive testing.

Deploy

Ship to production with SSL, monitoring, health checks, and zero-downtime deployment strategies.

Optimize

Monitor performance, refine workflows, and scale the system as your business grows.
