I've lived, breathed, and practiced real Agile since 2005, coaching teams and helping companies discover better ways to work through Lean, Kanban, Agile principles, and methods like XP and DTA/TTA.
I've spent over a decade building teams and mentoring people, teaching soft skills and technology daily — selling projects, hiring, building solutions, running coding dojos, long retrospectives, weekly 1:1s, design sessions, code reviews, and my favorite debate club: architects' communities of practice and development groups.
I've led complex architecture and engineering teams guided by SOA principles, using open-source languages like Java, Scala, Rust, Go, Python, Groovy, JavaScript, and TypeScript; AWS and Google GCP; Akka, ActiveMQ, Netty, Tomcat, and Gatling; Cassandra, Redis, Elasticsearch, OpenSearch, and RabbitMQ; Spring, Hibernate, Spring Boot, and the NetflixOSS stack. I've also implemented security at scale using AWS KMS, S3, ECS, EKS, Terraform, and Jenkins.
More than a decade of consulting — coding, designing, and training people at large customers in Brazil, London, Barcelona, India, and the USA — shaped my passion for functional programming, distributed systems, NoSQL databases, an observability mindset, and the habit of always learning new programming languages.
🌱 Currently: working as a hands-on lead Software Architect with AWS public cloud and Kubernetes/EKS, performing complex cloud, library, server, and persistence migrations, and security at scale with multi-level envelope encryption solutions using KMS and S3. Building complex multi-step debit orchestration systems with Java 25, Scala 3x, Kotlin, and Python 3x, while still hiring, teaching, mentoring, and growing engineers and architects. In my free time, I love playing guitar, gaming, coding POCs, and blogging. I blog actively at http://diego-pacheco.blogspot.com.br/
