Jigar Savani

Founder & Principal Consultant, FormulaSurge

I'm a senior Excel practitioner. I build dashboards, automations and financial models in Excel for finance, operations and analytics teams. The practice is remote-first; every engagement has me as the named owner from first reply to recorded walkthrough at handover.

Background

I've spent over a decade in Excel - first as a finance analyst building month-end close workbooks. FormulaSurge is my new independent practice, where I now take on freelance projects. The work spans Excel automation (Power Query pipelines, VBA macros, scheduled refreshes), dashboard design for CFOs and plant heads, end-to-end data analysis work, and three-statement financial modelling.

The practice is new and remote-first, open to clients anywhere. Every project runs on call, screen-share and WhatsApp, with the same fixed scope, fixed price, and written handover regardless of the city.

The rule I run the practice by is simple: every engagement has a named senior owner (me) from the first call to the recorded walkthrough at handover. No juniors, no quote-on-callback, no open-ended billing.
