Senior / Lead Software Engineer
I'm Bruno Matavelli, a senior / lead software engineer with 15+ years of experience designing, building, and scaling enterprise, financial-services, and SaaS systems. I'm also an AWS Certified Solutions Architect, with hands-on experience across cloud architecture, full-stack development, distributed systems, and legacy modernization.
I take ownership across the full software lifecycle: translating ambiguous requirements into architecture, implementing reliable applications and APIs, supporting production systems, and continuously improving them over time.
Most of my career has been spent doing the work that comes after the prototype: designing and building systems that handle real users, real data, and real consequences when they fail. I've led architecture and modernization initiatives across some challenging domains:
- Financial Services: Built and maintained customer-facing trading and investment platforms at Itaú Unibanco and Bradesco, working with sensitive financial data and distributed banking systems
- Enterprise Platforms: Designed scalable e-learning and integration systems at KPMG supporting global teams
- SaaS at Scale: Led engineering at CiiRUS, architecting cloud-native solutions for a platform supporting 400+ property management companies and 30,000+ vacation rental properties
That experience taught me something crucial: understanding where production systems actually break, and how to fix them without stopping everything else.
My Expertise
Cloud & Architecture: I design and build on AWS (Lambda, API Gateway, CloudFront, RDS, DynamoDB, ElastiCache) with a focus on serverless architecture, CI/CD pipelines, and high-availability systems.
Backend Engineering: Deep expertise in C#, .NET, Node.js, and building robust REST APIs, microservices, and integrations at scale. I've designed high-volume data synchronization systems processing millions of API requests.
Frontend Development: Experienced with Angular and React, TypeScript, and modern web standards. I led the migration of legacy ASP.NET applications to modern Angular frontends, significantly improving security and developer productivity.
Real-World Impact: I've built monitoring platforms that reduced customer-reported incidents by 60%, implemented Redis/ElastiCache strategies to optimize high-volume workloads, and developed AI-powered content generation tools now used in production.
Modernization & Production Engineering
Modernization is more than replacing a legacy framework. It means understanding the business workflows, preserving what works, and creating a safer path toward maintainable, scalable systems.
My work includes cloud architecture, API design, application performance, observability, CI/CD, security, and operational reliability. AI-assisted development can be useful leverage, but production systems still require careful engineering judgment and human ownership.
My Approach
I'm practical and engineering-first. I focus on clear tradeoffs, measurable outcomes, and systems that can be understood and operated by teams over the long term. I believe in SOLID principles, thoughtful design patterns, and code that's maintainable by the next person who reads it.
I also mentor developers and provide technical leadership. Good software comes from good teams, and I've consistently worked to build engineering cultures focused on quality, collaboration, and continuous learning.
