Excel add-in
NavD
Trace every number in a financial model: precedents and dependents with captions and periods, formula trees, a model audit and banker-style formatting cycles — keyboard-first.

Where investment banking meets engineering.
Rodrino is the independent studio of an investment banking professional who is also a computer engineer. Years of building and defending financial models, now turned into software that makes that work faster and safer — and the first projects are starting to come out.
Projects
Tools from a working toolbox
Each project started as something needed on a real deadline. The ones that proved themselves are being rebuilt and released.
PowerPoint add-in
NavD Watermark
Stamp every slide with “Prepared for …” and export a personalised PDF for each recipient in one batch, delivered as a single ZIP.
In the workshop
More to come
Automation for the documents and models bankers live in — from model checks to the busywork around client materials.
Profile
Two disciplines, one way of working
Rodrino sits on a rare overlap: the judgement of someone who ships deliverables in investment banking, and the toolkit of someone trained to build software.
01 · Finance
Investment banking
Works in investment banking at a top-tier firm, where financial models and client materials are produced under real deadlines and every number has to tie out.
- Financial models built, reviewed and defended
- Client-ready materials, on deadline
- A trained eye for what looks wrong in a model
02 · Engineering
Computer engineering
A computer engineer by training, with many years of hands-on software experience and a lasting interest in technology — from automation scripts to modern web platforms.
- Software design and development
- Office automation: VBA, .NET, Office.js
- Cloud, web and the tooling around them
The overlap is the point.
Most tools for bankers are built by people who have never had to defend a model the night before a deadline. These are built by someone who has — and who can write the code to remove the friction.
Approach
From private toolbox to products
Macros
It started with VBA: small fixes for the things that slowed every model review down.
.NET add-ins
The macros grew into full VSTO add-ins in C#, used daily on real deadlines.
Modern Office
Rebuilt on Office.js — the same tools on Windows, Mac and the web.
Released
Now the proven ones are being published, starting with NavD.
Principles
Every number traceable
Good tools show where numbers come from. Nothing should be a black box.
Keyboard first
Speed comes from never reaching for the mouse in the middle of a thought.
Private by design
Your files stay on your machine. No accounts, no tracking.
Built for deadlines
Reliable, fast and learnable in minutes — because there is never time.
