Hi, I'm Bryan Acuña.
Automation engineer
& SaaS builder.
I lead an underwriting team at Funding Metrics. My day-to-day: find the processes worth automating, integrate AI into reporting and risk analysis, and turn ops bottlenecks into internal tools. On the side, I designed and built Nexo Barber end-to-end: a multi-tenant SaaS for barbershops, live in production.

03. About
I work the gap between business operations and engineering. The first half of my career was underwriting and data quality: finding where the numbers do not add up. The second half added the engineering side: when standard tools could not fix the problem, I started building tools that could.
Today I supervise underwriting and reporting at Funding Metrics, automating validation pipelines and dashboards in SQL, Power BI, and Tableau. On the side, I design, build, and operate Nexo Barber, a multi-tenant SaaS for barbershops shipped end-to-end in Next.js and Supabase.
I bring the risk discipline of an underwriter and the product mindset of a builder. I am fastest when those two collide: validation-heavy data work, operational analytics, internal tooling, and product engineering for fintech-adjacent systems.
04. What I do
01
Data engineering & analytics
SQL-first work, from raw bank statement and Salesforce data to dashboards senior management actually opens. Window functions, validation pipelines, risk pattern detection.
SQL · Python · pandas · Power BI · Tableau · Excel + VBA · Salesforce

03
Operational automation
When standard tools cannot fix the problem, I build the tool that does. Google Apps Script for serverless internal tools, Excel macros for the recurring stuff, prompt engineering for the AI-shaped parts of the job.

Underwriting & risk
Nine years of merchant cash advance underwriting. Bank statement analysis, ACH and NSF pattern reading, fraud indicator detection, pre-approval logic. The lens I bring to every product decision: assume a hostile actor on the other side of the form.
