About this gig

Hi, I'm Andy a senior full-stack developer with 25+ years of experience. I recently architected and built an entire in-house marketing CRM that fully replaced HubSpot for a retail company: contacts, dynamic segmentation, multi-step email automation, A/B testing, suppression/bounce handling and analytics dashboards.

Stack: ASP.NET Core, C#, SendGrid API, SQL Server. Clean, documented, production-ready code.

I'm Andy, a senior Full Stack Developer & CRM architect with 25+ years building enterprise web, mobile and marketing systems. Most recently I designed and built an in-house marketing CRM that fully replaced HubSpot — SendGrid email automation, dynamic segmentation, forms and analytics dashboards — and shipped a published React Native app (iOS & Android) with payments, loyalty points and push notifications. From requirements to deployment, I deliver clean, scalable, production-ready code that drives real business value. Let's build something great.
