Work Experience

D

Digital Essentia Remote

July 2024 - Present
AI Engineer & Software Consultant
Designing and delivering AI-powered solutions for clients across web, SaaS, and automation use cases. Integrated LLM APIs (OpenAI, Claude, Gemini) with prompt engineering frameworks, structured output pipelines, and multi-model routing. Built AI workflow automations and RAG pipelines using Python, FastAPI, and REST integrations — reducing manual processes with measurable throughput improvements. Delivered containerized AI applications with full observability via OpenTelemetry and LangFuse. Worked cross-functionally with non-technical stakeholders to identify automation opportunities, define success metrics, and document workflows for team adoption.
