About Hermano Ferreira

I am a results-driven engineer with an MS in Data Analytics and 15+ years of international experience in the energy sector. I spent over a decade in Oil & Gas before pivoting into software engineering for datacenter energy supply, where I work hands-on on digital transformation and data-driven operational efficiency. This path gives me a rare combination of deep domain expertise and modern software engineering skills.I specialize in turning operational data into resilient, automated systems that improve reliability, performance, and cost efficiency. I thrive at the intersection of business strategy and technical execution, translating complex requirements into scalable solutions. My blend of energy domain knowledge and technical proficiency enables me to deliver high-impact outcomes and measurable value for organizations operating where energy and technology converge.

Experience

1. Senior Software Engineer

   Lancium

   Jan 2022 — Present · Houston, TX, US

   Design, build, and support data and control systems for large-scale datacenter power facilities, with a strong focus on Infrastructure as Code (IaC), AWS, and event-driven automation.Own IaC for multi-account AWS environments (separate dev and prod), using CloudFormation and Ansible to standardize provisioning, configuration, and deployments.Design and operate workloads on EC2 and Lambda, including event-driven integrations with EventBridge and notifications via SNS.Define and manage security groups and related controls to enforce least-privilege access and safe network boundaries across environments.Execute in-depth data analysis across multiple facilities to generate actionable insights on power frequency response (PFR) and operational efficiency.Develop automated award and settlement systems for power regulation response, reducing manual effort and improving process reliability.Architect event monitoring frameworks that support complex event definitions (including rate-of-change logic) to detect anomalous behavior.Drive architecture modernization to improve query performance, reduce latency, and enhance system scalability.Establish comprehensive monitoring (metrics, health checks, logging, alerting) across cloud and on-prem environments.Design containerized testing infrastructure, including a custom simulator, to improve automated testing and coverage.Enhance CI/CD pipelines with automated checks and deployment safeguards, increasing release safety and developer productivity.Engineer ETL pipelines that feed high-value analytical workloads, including auto-tuning model development and validation.Implement metrics collection and visualization via Grafana dashboards for real-time visibility into system and facility performance.Technical Stack: Python, Django, PostgreSQL, VictoriaMetrics, AWS (EC2, Lambda, EventBridge, SNS, CloudFormation, Security Groups), REST APIs, JavaScript, Ansible, Grafana, Git, CI/CD
