About Me

15 Years Shipping
Enterprise Software

For 15 years I've been one of a handful of engineers responsible for three enterprise applications and two APIs — no dedicated QA, no separate front end and back end teams, just a few developers who own the whole thing. I write a majority of the production code, make architecture calls, handle deployments, mentor the junior devs, and still jump on a support ticket when something breaks at the wrong time.

On the side I take on consulting work — websites, internal tools, whatever's interesting. Same standards as the day job.

What I Do

Expertise

Architecture, full-stack delivery, and engineering ownership across the whole system — from data layer to UI. Websites that bring in customers, custom apps that replace your spreadsheets, and the SEO that gets you found.

Websites & Landing Pages

Fast, modern websites built to impress. Clean code, solid performance, no templates.

Enterprise Application Development

Full-stack enterprise apps built to handle real scale — complex data models, multi-client architectures, and the kind of requirements that change halfway through.

System Architecture & Scale

Multi-database data layers, command-pattern backends, codegen pipelines, real-time cache invalidation. The architecture work that takes a system from prototype to Fortune 100 production.

Custom Business Apps

Purpose-built internal tools and client-facing apps. If you're still running a business process in spreadsheets, this is the card for you.

Internal Tools & Workflows

Configurable, role-based apps for internal teams. Reporting pipelines, EDI transmission, batch processing, dashboards — built to integrate with the rest of your enterprise stack.

API & Integrations

REST APIs, third-party integrations, and system glue. If two things need to talk to each other, I can make that happen.

Tech Consulting & AI

Architecture reviews, AI tooling integration, workflow automation. I've built self-hosted LLM infrastructure and shipped AI-driven apps — happy to help you figure out what's actually useful for your situation.

My Work

Portfolio

Enterprise systems and personal projects from the last few years. A selection of sites and apps I've built — most shipped solo.

CPG Promotions & Order Management Platform

Confidential — Wholesale & Retail Portals

Internal / Proprietary

A dual-portal enterprise platform serving a national wholesale distributor and retail store network in the CPG/beverage industry. Built from the ground up with a team of 4–5 engineers — a Wholesale Portal for distributor and sales team workflows and a Retail Portal for store representatives. Covers promotional offer management, order entry, retail preferences, EDI transmission, compliance, and analytics across 100+ API endpoints and 130+ database tables.

▸Architected command-pattern business layer decoupling all logic from thin API controllers — 80+ command classes across the system enabling clean, reusable, and independently testable components
▸Integrated 10+ external systems including SAP (invoicing), Azure AD (auth), EDI transmission networks, Azure Data Lake, Teradata data warehouse, Oracle, and JDA/Blue Yonder supply chain
▸Designed cross-database data layer spanning SQL Server (×4), Oracle, and Teradata — all unified behind the same command abstraction
▸Built server-side report generation pipeline (Aspose.Cells), Chart.js analytics dashboards, and configurable EDI order transmission with retry and failure notification
▸Implemented role-based authorization with job assignment security across all API endpoints and Angular route guards; managed schema-first DB development using SQL Server Projects with DACPAC deployments

Fortune 100 Client Enterprise SPA Full Stack Built from Scratch

Enterprise Promotional Management Platform

Confidential — Consumer Goods Industry

Internal / Proprietary

A large-scale promotional management platform architected and built from the ground up alongside a team of 4–5 engineers for a Fortune 100 consumer goods company. The system orchestrates pricing, promotions, payments, product master data, forecasting, audience targeting, compliance reporting, and real-time data synchronization — spanning 30+ feature modules across multiple business lines.

▸Designed and built a versioned (v1/v2) ASP.NET Web API backend with OWIN middleware, OAuth2, custom claims-based RBAC, and impersonation support
▸Created a T4 code generation pipeline that auto-generates POCOs, CRUD commands, service controllers, Angular TypeScript models, and report import classes directly from SQL Server schema — eliminating boilerplate across the full stack
▸Built a custom criteria-based audience targeting and allocation engine with geo/state segmentation
▸Implemented real-time SQL cache invalidation to keep distributed server caches in sync without polling
▸Unified SQL Server (OLTP), Azure SQL, and Teradata analytics warehouse through a single command-pattern data layer; integrated multiple external payment and order management APIs
