What is the difference between Software Engineering and Web Development?

Software Engineering is a broader discipline that includes system architecture, design patterns, automated testing, CI/CD, and code best practices. Web Development might just be creating interfaces and basic functionality. Software Engineering ensures the system is scalable, maintainable, and high quality.

How long does it take to develop a complete system?

It depends on complexity. Simple systems: 2-3 months. Medium systems: 4-6 months. Complex/enterprise systems: 6-12 months. We work with agile methodology (2-week sprints) with incremental deliveries, allowing adjustments during development.

What technologies do you use?

Frontend: React, Next.js, TypeScript, Tailwind CSS. Backend: Node.js, NestJS, Python, FastAPI. Mobile: React Native. Database: PostgreSQL, MongoDB, Redis. Cloud: AWS, Google Cloud, Vercel. Architecture: Microservices, REST APIs, GraphQL, Event-driven. DevOps: Docker, Kubernetes, CI/CD (GitHub Actions).

Do you provide maintenance after delivery?

Yes. We offer post-delivery support and maintenance with defined SLA. This includes bug fixes, security updates, performance improvements, and new features. We also train your team for system operation autonomy.

What is your development process?

We follow agile methodology: 1) Discovery (requirements gathering), 2) Planning (architecture and sprints), 3) Iterative development (deliveries every 2 weeks), 4) Testing (automated and manual), 5) Staging (client validation), 6) Deployment (production), 7) Support and maintenance.

Software Engineering - Custom development

What Is Software Engineering?

Software Engineering is the systematic application of engineering principles to the development, operation, and maintenance of software. It involves requirements analysis, architecture design, coding with best practices, automated testing, and continuous maintenance. We use agile methodologies (Scrum/Kanban) with 2-week sprints, modern stack (React, Next.js, TypeScript, Node.js, Python), and scalable architectures (microservices, REST APIs, GraphQL).

Complex System Development

When you need an enterprise system with multiple modules, integrations with other systems, and scalability and performance requirements.

Legacy Software Modernization

When old systems need to be rewritten with modern technologies while maintaining or improving existing functionality.

Scalable Digital Product

When building a SaaS product or platform that needs to support thousands of simultaneous users with high availability.

Complex Architecture Application

When the project requires microservices, distributed APIs, asynchronous processing, or complex integrations.

High-quality, maintainable code
Scalable architecture for future growth
Automated testing (unit, integration, E2E)
Complete technical documentation
CI/CD for automated deployments
Code review and pair programming
Reduced production bugs
Easy to onboard new developers
Optimized performance

Methodology

The 6 Principles of AI-Native Architecture

The same redesign that took a São Paulo fintech from 50 to 5 engineers — cycle time from 3 weeks to 3 days. We apply these principles to every system we build.

Explicit over Implicit

Every decision, convention, and business rule exists as machine-readable code or spec.

AI agents see the what and why — no guessing required

Small, Composable Modules

No file over 200 lines. Each module does exactly one thing.

Manageable context for AI to operate precisely

Contract-First

APIs, schemas, and interfaces defined before implementation.

AI generates correct code without ambiguity

Deterministic Tests

Zero flaky tests. Same result on every execution.

AI knows if it broke something — not the infrastructure

Self-Describing Systems

AGENTS.md + OpenAPI + Zod + TypeScript + database schema.

Any agent reads the manual before touching the code

Automated Verification

Every quality gate produces machine-readable JSON output.

AI triggers, reads, and acts on results autonomously

Incremental migration — not a rewrite

From any codebase to AI-Native in 4 weeks, without stopping operations.

Week 1

Create AGENTS.md and document critical system ADRs

Week 2

Break the 5 largest files into composable modules

Week 3

Add OpenAPI and Zod to main routes

Week 4

Eliminate flaky tests and reset database in beforeEach
