About

Hey, I’m Demaro.

I’m a Software Engineer II working in enterprise investment technology, where I build and maintain applications and data infrastructure that supports Portfolio Managers, private placement pricing analysts, and investment credit scoring analysts.

My day-to-day involves three main areas: building modular investment apps in C# and .NET, maintaining data pipelines that move files between Bloomberg and Clearwater into our own data layer — including Bloomberg Data License premium data via SFTP — and working on a credit scoring assessment module that helps analysts score, track, and benchmark investment performance.

I started this blog because I kept running into the same problem: the intersection of software engineering and institutional investment operations is poorly documented. Most technical writing either targets generic web developers or finance professionals — almost nothing is written for engineers who sit squarely between the two. I’m trying to fill that gap with writing that’s honest, specific, and grounded in real systems.

What I write about

My writing focuses on four areas:

  • Data integration — Bloomberg DL, Clearwater, SFTP pipelines, and making financial data usable inside your own systems
  • AI and ML in finance — practical applications of machine learning in investment workflows, credit scoring, and financial document analysis
  • Financial software architecture — .NET modernization, C# patterns for enterprise investment apps, and the tradeoffs that matter in regulated environments
  • AWS for financial systems — cloud architecture for data pipelines, compliance considerations, and lessons from building on AWS inside a financial services company

Background

I hold the AWS Developer Associate certification and am actively studying for the Solutions Architect Associate exam. I’m drawn to the architecture side of cloud — particularly where financial data, compliance, and system design intersect.

Outside of work I’m interested in personal finance, investing, and building income streams beyond a 9-to-5. That curiosity bleeds into my writing — I think about financial systems from both sides of the screen.

The digital products

Alongside the blog, I’m building a small library of practical guides for financial engineers. The first — a deep-dive on Bloomberg Data License SFTP integration — is in progress. If you subscribe to the newsletter, you’ll hear about it first.
