Context

Where the product lives

Sistemas Lenox builds business software for companies that run on operational processes: employees, documents, sales and internal administration.

Problem

What makes it hard

Internal software usually fails when it ignores how people actually work. The systems had to reflect real processes, handle a lot of structured data and remain reliable for daily use.

Work

What I worked on

  • Building an employee-management PWA.
  • Implementing document workflows.
  • Developing .NET MVC applications and internal sales software.
  • Working on database-oriented tools and reporting.

Decisions

Technical decisions

  • Understand the operational process before designing screens.
  • Keep data models close to how the business names and uses things.
  • Prioritize reliability and clarity over visual novelty in internal tools.

Product

Product considerations

  • Internal users are experts in their process; the interface should respect that.
  • Offline-tolerant and installable interfaces help teams that are not always at a desk.
  • Document and approval flows need clear states and history.

Outcome

What changed

Shipped internal and client-facing systems used in daily operations. This period shaped how I approach product work: workflow first, framework second.
