What I'm looking for

I’m looking for a team that values clean, efficient code and proactive problem solving—where I can build scalable, secure backends and data pipelines, own CI/CD automation, and collaborate closely across product, security, and frontend to deliver real impact.

I’m a Senior Python Engineer with 9 years of experience crafting robust backend systems and data pipelines, using Python and Django to build scalable, secure web applications and automate complex workflows. I thrive on partnering across teams to deliver high-performance solutions that solve real-world problems in dynamic, fast-paced environments.

At Thoughtbot, I architected integrations with DNS providers like Cloudflare and GoDaddy to ensure robust API reliability for external partners. I optimized backend systems with Python and Django using AWS Lambda, EC2, and DynamoDB for high availability, and I streamlined CI/CD pipelines with AWS CDK to enable faster, more reliable deployments across distributed environments. I also owned backend architecture for a DNS platform and guided junior developers in Python best practices and system design.

Previously, at A3logics, I engineered custom plugins for cybersecurity software by integrating with Elasticsearch and Splunk for real-time threat detection, and I designed data models and indexing strategies across MongoDB and relational databases to optimize query performance. I managed Docker and Kubernetes environments on AWS, automated infrastructure provisioning with Ansible and Terraform, and helped implement encryption and access controls. In earlier roles, I combined Python/Django automation with React.js improvements, supported customers through technical troubleshooting, and created guides and trainings—skills that still shape how I communicate and deliver engineering work today.
