Hi, I'm

Cesar Ortiz

Full Stack Developer & Founder

I build products that solve real problems — from architecture to deployment.

From Accounting to Building SaaS Products

About Me

I didn't take the traditional path into tech. My career started in accounting and finance, where I learned to think in systems — tracking flows, balancing inputs and outputs, and understanding how small errors compound into big problems.

That analytical mindset followed me when I made the leap into software development. Self-taught and driven, I spent years mastering the fundamentals: JavaScript, TypeScript, design patterns, and architecture principles — before ever touching a framework.

Today, I'm the CEO & Co-Founder of NevadaTech, where we help businesses transform their operations through technology. I architect systems using Clean Architecture, Hexagonal Architecture, and Domain-Driven Design — because I believe the structure of your code should reflect the structure of your business.

When I'm not building products, I'm mentoring developers and advocating for a foundation-first approach to learning. The shortcuts don't work. The fundamentals always win.

Concepts > Code

Understanding WHY before writing HOW. Frameworks change; principles don't.

Architecture First

Clean, Hexagonal, DDD. The structure should scream the domain.

Foundations Before Frameworks

Design patterns, TypeScript, bundlers — then React.

Build Products, Not Projects

Think like a founder: business impact, user experience, maintainability.

My approach to building software

How I Think

I don't start with code. I start with the problem. Every project begins with understanding the domain, defining boundaries, and choosing the right patterns — before a single line is written.

Understand the Domain

Before writing code, I immerse myself in the business problem. Who are the users? What are the pain points? What does success look like? The best architecture comes from deeply understanding what you're building.

Define Boundaries

I break complex systems into bounded contexts. Each module owns its domain, exposes clear interfaces, and hides its implementation. This is where Hexagonal Architecture and DDD shine.

Choose Patterns Intentionally

Not every project needs DDD. Not every API needs GraphQL. I choose patterns based on the problem's complexity, the team's expertise, and the project's lifecycle. The right tool, not the trendy one.

Build with Confidence

Tests aren't an afterthought — they're part of the design. 97% coverage on my inventory system isn't vanity; it's the confidence to refactor, scale, and ship without fear.

Ship and Iterate

Perfect is the enemy of shipped. I build MVPs, gather feedback, and iterate. But I never sacrifice architecture for speed — because technical debt always comes due.
