• Automation of network and security configurations • Building and enhancing DevOps infrastructures • Containerization with Docker & Kubernetes • Infrastructure as Code (Ansible, Terraform, etc.) • Automation of CI/CD pipelines • Advising clients on new technologies • Project leadership and technical responsibility

• Run structured discovery sessions with clients to map current workflows, pain points, and manual bottlenecks • Identify realistic AI automation opportunities — and just as importantly, tell clients when AI isn't the right tool • Build business cases for automation initiatives: time saved, error reduction, cost impact • Prioritize a roadmap of opportunities based on feasibility, ROI, and client readiness • Maintain trust with clients by setting honest expectations and delivering on them • Translate discovery findings into working automations using tools like n8n, Zapier, Make, LangChain, or custom Python pipelines • Integrate LLMs (OpenAI, Claude, Gemini, etc.) into internal tools, data pipelines, and business processes • Write clean, maintainable code — Python primarily, with some JS/TS as needed • Monitor, maintain, and iterate on automations post-launch
