Automations & Integrations

Your CRM, billing platform, and Microsoft 365 probably don't talk to each other. We build the integration layer that connects them — using tools like Workato, Azure Logic Apps, and custom API work — so data moves automatically instead of getting copied by hand between systems.

Real projects for public-sector and private clients, replacing manual processes with software that works.

Public Sector

Vendor Data Access Portal for a Municipal Utility

Built a FastAPI service on top of the town's CIS Infinity billing platform, letting waste-hauling vendors check resident eligibility for a free-dumping program in real time instead of emailing spreadsheets back and forth. Manual lookups dropped from ~2 days to under 2 seconds.
