Hi, I'm
Pablo F. Ramos
Software Engineer focused on enterprise systems — building reliable backends, APIs and ERP integrations with C# and .NET.
Background
I'm a Software Engineer focused on enterprise software, backend development and reliable systems.
I have around five years of professional experience building and customizing enterprise software, mainly with C#, .NET and SQL Server. My day-to-day work centers on backend development, REST APIs, data integrations and adapting ERP systems to real business needs.
I care about maintainable, well-tested code and pragmatic problem solving. I apply SOLID principles, work within Agile/Scrum teams, and I'm comfortable across the stack — from database design and API security to external integrations.
I'm especially interested in finance, investments and emerging technologies, and I enjoy building software around them — my personal project Mony is one example.
I also lean heavily on modern AI tooling — coding agents like Claude Code — as part of my daily workflow. Used well, they take care of the repetitive work and let me stay focused on architecture and decisions, boosting my productivity enormously.
Tools I reach for first

Personal projects built in my free time — most of my professional work is under NDA.
Mony: Finance Tracker
FeaturedPersonal Project · 2026
Take control of your money — track, analyze, improve.
Mony is a private, offline-first personal finance app I designed and built end to end. It turns everyday spending into clear insights — no account, no cloud, no tracking. Everything runs 100% on your device.
Most finance apps make you log every single expense by hand — so tedious that you give up after a week. And they lock you into rigid calendar months that never match how you actually get paid or budget.
Mony recognizes your expenses automatically from bank & payment notifications — you just approve or reject each one with a tap. Custom financial cycles let you start the period on any day of the month and set your own cycle length, so it fits your real life.
More things I've built
WarTrade
The marketplace for the Warhammer & miniatures hobby.
A specialized marketplace where hobbyists can buy, sell and trade Warhammer miniatures — new, used or painted. Features include commission painting services, community groups, a full miniatures catalogue, army builder, wishlists with alerts, trend tracking, and buyer/seller protection with Stripe checkout.
Web Design & Development
Custom websites, built on commission.
On the side, I design and build custom websites for clients — from personal portfolios to small-business landing pages. This very site is one of them: hand-built from scratch with Next.js and React, fully responsive and bilingual.
System Integrations
Connecting systems via APIs & web services.
I build integrations that connect business systems over REST APIs and web services. Many of them run through Excel — moving data between spreadsheets and live systems to automate reporting and manual workflows.
