Profile

Senior AI Engineer with 6+ years building end-to-end ML and GenAI systems across voice, retrieval, and applied NLP, including published work with the NVIDIA NeMo team. I work where research meets production: LLM-powered products, voice agents, RAG pipelines, multi-agent orchestration, and the evaluation and observability that keep them reliable. Beyond the model, I shape system design, define KPIs, and connect technical work to business outcomes.

Selected work

Systems I have shipped.

Production engineering and the research that backs it: voice, retrieval, and the evaluation infrastructure that tells you a model is actually safe to ship.

Where research meets production.

I build end-to-end ML and GenAI systems across voice, retrieval, and multi-agent orchestration, from the research that de-risks a hard problem to the evaluation and observability that keep it reliable at scale. Published work alongside enterprise products shipped to production.

Visual RAG Toolkit

Multi-vector retrieval over documents, matching against page images, not just extracted text, so tables, figures, and layout survive the pipeline. Accepted to SIGIR 2026.

Speech data for low-resource languages

A pipeline that manufactures training data where almost none exists, via audiobook alignment, crowdsourcing, and pseudo-labeling, so ASR reaches languages large models overlook. Built with the NVIDIA NeMo team.

Naira Radzievsky Head of AI, Co-Founder
★★★★★5.0 · Jan 2026 · IT consulting
I worked with Ara on several complex AI initiatives, and he consistently showed a rare mix of deep technical expertise and work ethic. As I came to trust his judgment, I often sought his input on research and project direction, realistic estimates, and how to structure work and involve other specialists. His guidance was consistently practical and aligned with both technical and business goals, making him a reliable contributor for production-grade solutions and critical decision-making.
Karsten Luc
Karsten Luc Co-Founder, AKRYL.consulting
★★★★★5.0 · Dec 2025 · IT consulting
Ara is a highly capable engineer who can take ownership of complex projects end to end. At Akryl digital agency, he was responsible for the full lifecycle of our Visual RAG and LLM orchestration pipelines over more than six months, covering research, implementation, benchmarking, and deployment. Ara brings a solid combination of technical depth and practical execution and would be a strong contributor to any team.

Beyond the work

Off the keyboard.

Three pursuits I've taken as seriously as the engineering: the board, the mat, and the court.
