02
Web platforms
Astro and React sites, dashboards and internal portals with performance, SEO and conversion-focused architecture.
03
IoT & embedded
ESP8266/32 telemetry, ultrasonic sensing and MQTT ingest using the same patterns behind traffic monitoring and tank-level prototypes.
04
Cloud & backend
PostgreSQL, serverless APIs and Cloudflare Pages Functions that keep clients thin and business rules server-side.
05
Product engineering
Architecture reviews, technical scoping and delivery plans that keep complex builds on schedule from discovery through handoff.
Why VersaCarte
One team from architecture to App Store review
Clients get API, web UI and mobile apps under one roof instead of three vendors who hand off blame. We design for real-world conditions including variable connectivity, diverse devices and the payment methods your market expects.
- End-to-end delivery from APIs and cloud backends to polished web and mobile UI
- Documented architecture you can audit, extend and hand off
- Global perspective with support for local payments, languages and connectivity

What collaborators say
"Gerard approaches software the way a good electrical engineer approaches a panel. Every connection is documented and every failure mode is considered. The Smart Traffic prototype showed production-grade thinking in a university project."
"Clear communication, realistic timelines and code I could actually read during handoff. VersaCarte delivered FileSendNX with the kind of polish you expect from a much larger team."
