I revamped the Digital Customer Assistant — the automation that streamlined customer contact and logistics — with optimized data retrieval and writing, database tuning, and refactored code for smoother, faster operation.
Keeping a Workhorse Sharp
The Digital Customer Assistant had already proven itself, cutting unscheduled deliverables and maximizing truck efficiency. But a tool that runs every day accumulates cruft. Keeping it fast and stable meant going back into the engine — data access, database, and code — and modernizing it.
What I Delivered
Optimized data access
Reworked how the DCA retrieves and writes data for better performance and stability.
Database optimization
Tuned the database so the assistant responded faster under real-world load.
Code refactoring
Refactored the codebase for cleaner, more maintainable, and faster operation.
Faster, smoother ops
Delivered quicker response times and smoother day-to-day operation across the board.

The Impact
A modernized Digital Customer Assistant that’s faster and steadier than before — still cutting unscheduled deliverables and maximizing truck efficiency, now on a cleaner, better-tuned engine.
Maintenance Is a Feature
The best tools don’t just get built — they get maintained. Refactoring the DCA’s data access, database, and code kept a proven workhorse fast, stable, and ready to keep delivering the efficiency it was built for.
