Hi, I'm Mary Soarez 👋

Software Engineer | Flutter Specialist | Full Stack Development

Mobile Engineering • Software Architecture • AI-Assisted Development

I'm a Software Engineer based in Rio de Janeiro, Brazil, specializing in Flutter/Dart, mobile architecture, and cross-platform application development, with experience across frontend, backend, and cloud technologies.

I've worked on applications across mobility, healthcare, logistics, and digital platforms, contributing to the full software development lifecycle — from technical discovery and architecture decisions to implementation, testing, deployment, and production monitoring.

I enjoy bridging engineering, product thinking, and business needs, building maintainable solutions that solve real problems.

Currently expanding my expertise in AI Engineering, coding agents, context engineering, and Spec-Driven Development (SDD).

🧩 My Engineering Approach

Great software starts with understanding the problem, not writing code.

  1. Discover — Understand user needs, business goals, and constraints.
  2. Design — Evaluate alternatives, trade-offs, and architectural decisions.
  3. Build — Develop maintainable, testable, and scalable solutions.
  4. Validate — Apply automated testing, code reviews, and quality practices.
  5. Observe — Monitor application behavior and production performance.
  6. Improve — Learn from feedback, metrics, and real-world usage.

I value pragmatic architecture, collaboration, technical ownership, and continuous improvement.
