Custom Software & AI Services Across the RGV and Texas
Based in McAllen and serving businesses throughout Hidalgo, Cameron, and Starr counties, with custom software and AI development available to companies across Texas.
About / Founder
Engineering software from the workflow backward.
I started programming in 2017 and later earned a Bachelor of Science in Computer Engineering from the University of Texas Rio Grande Valley.
My approach starts with understanding the operation behind the software: what people do, where information moves, what decisions require human judgment, and which repetitive steps are worth automating.
From there, I design full-stack systems with clear data models, maintainable architecture, role-aware workflows, and AI only where it provides a practical advantage. The goal is software that remains understandable and useful as the business evolves.

Engineering Approach
How I approach a software system
The technology comes after the workflow. I first map how people complete the work, where the data comes from, where bottlenecks occur, and which decisions should remain under human control. The architecture follows those requirements.
Business-First Design
Map the real workflow, users, bottlenecks, and business rules before choosing the architecture.
Maintainable Architecture
Separate responsibilities clearly so features, integrations, and data models can evolve without turning the system into a fragile monolith.
Human-Controlled AI
Use AI where reasoning or language adds value while keeping approvals and high-impact decisions under human control.
Traceable Data
Design workflows so important changes, transactions, and system decisions can be validated, understood, and audited.
Systems / Architecture
The architecture behind reliable business software
My systems work goes beyond interface development. I design the data, permissions, validation rules, workflow boundaries, and integration points that keep business software reliable behind the screen. Depending on the application, that can include role-based access, transaction history, payroll validation, reporting pipelines, automation rules, and AI-assisted analysis.

Pattern, anomaly, and operational-data analysis
- Designing an AI layer to surface meaningful patterns, trends, and anomalies in operational data
- Exploring predictive analysis for identifying unusual payroll or business activity earlier
- Connecting analytical output back to the underlying business systems so insights remain grounded in real data
Workflow Automation
Internal Operations & Workflow Automation Systems

Feedback from people who have seen my work, technical approach, and software projects firsthand.
Reference
Ruben is incredibly knowledgeable when it comes to software development, AI tools, and modern web technologies. You can tell he genuinely cares about building high-quality systems and continuously improving his projects. I've had the chance to see some of the dashboards, automation ideas, and web application concepts he's been working on, and everything looks very modern, clean, and thoughtfully designed.

Frequently Asked Questions
Straight answers about custom software, AI automation, project development, and working with Ruben Arevalo AI & Software Studio.
Project ScopeIntegrationsPricingService Areas
What does Ruben Arevalo AI & Software Studio build?
I build custom software, AI automation, internal business systems, and web applications for businesses in McAllen, the Rio Grande Valley, and across Texas. Each system is designed around the way your team already works instead of forcing your operation into a generic template.
Can you replace an Excel, Access, or manual workflow with a custom web app?
Yes. If an important business process still depends on spreadsheets, Microsoft Access, repetitive data entry, or disconnected tools, I can map the existing workflow and rebuild it as a centralized web application with the permissions, reporting, automation, and data structure your operation actually needs.
What is the difference between an AI agent and a chatbot?
A chatbot primarily responds to messages. An AI agent can work through a defined process, use approved tools or business data, and take actions such as qualifying a lead, updating a record, generating a report, or routing work. For higher-impact decisions, I design human approval into the workflow instead of giving the model unrestricted control.
Can AI automation work with the software my business already uses?
Often, yes. AI and workflow automation can frequently connect to existing databases, APIs, CRMs, forms, spreadsheets, email systems, and other business tools. I first evaluate what you already use so we can determine whether integration, partial modernization, or a new internal system makes the most sense.
How much does custom software or AI automation cost?
Pricing depends on scope, integrations, workflow complexity, data requirements, security needs, and the amount of automation involved. I define the requirements first and provide a written scope and project price before development begins, so you know what is being built and what the engagement covers.
What kinds of businesses benefit most from custom internal software?
Custom internal software is especially useful when a team relies on repetitive manual work, multiple disconnected systems, difficult reporting, spreadsheets that have become business-critical, or processes that no longer scale. The goal is to centralize the workflow and reduce the operational friction behind it.
Do you only work with businesses in McAllen?
No. Ruben Arevalo AI & Software Studio is based in McAllen and serves businesses throughout the Rio Grande Valley, including Hidalgo, Cameron, and Starr counties, as well as companies across Texas. Most software development and AI automation work can also be delivered remotely.
What happens after custom software is launched?
The handoff can include deployment, documentation, configuration guidance, and training based on the project scope. Ongoing maintenance, monitoring, updates, and future development can also be defined separately so the system can continue evolving as your business changes.
Education / Foundations
Engineering foundations behind the work
My academic background helped build the foundation I use today across software engineering, systems design, data, and applied AI. That foundation now informs how I approach real business workflows and production software.
Bachelor of Science (B.S.)

August 2019 - May 2023
I earned my Bachelor of Science in Computer Engineering from the University of Texas - Rio Grande Valley in May 2023, with my concentration focusing on software development.
High School Diploma
Achieve Early College High School
August 2015 - May 2019
I earned my high school diploma in May 2019 from Achieve Early College High School, which came just after graduating with an associate's degree in computer science.
Associate of Science (A.S.)

I earned my Associate of Science in Computer Science from South Texas College in May 2019, just a few weeks before I graduated from high school.
From Foundation to Practice
Education is the foundation. Building systems is where it gets tested.
The concepts behind algorithms, databases, software engineering, computer systems, and applied AI become much more meaningful when they have to support real users, business rules, changing requirements, and maintainable software.

June 2025 - PresentJ.A.L.E. (Job Automation & Logistics Engine)
Managing content is only half the battle — executing the work is the rest. J.A.L.E. started as a personal content management system (CMS). It's growing into a full internal business software platform, including a Statement of Work (SOW) generator and an automated timesheet monitor that flags issues like missed clock-outs and missing lunch breaks. It's built to scale for studio creators and business owners, and it doubles as a reference architecture for full-stack developers and software engineers building their own internal business tools.
