Senior AI Engineer @ Digital Currency Group · Deep Learning Engineer @ Intel · Ex Data Scientist @ Nokia
Building production-grade intelligent systems, from fine-tuning LLMs and orchestrating AI agents to shipping decentralized ML at scale.
// About
I'm a Senior AI Engineer at Digital Currency Group, where I architect intelligent, decentralized AI systems that power real-world decisions. I specialize in production-ready AI agents with models like Qwen, LLaMA, Gemma, and Phi, orchestrated with LangChain, LangGraph, and Weaviate vector search, plus RAG, evaluation, and serving patterns used in production.
One of my proudest projects is VCScout-AI, an end-to-end autonomous agent that analyzed 300+ startup deals and directly drove $450K+ in AI-informed investments. My work spans federated learning, blockchain-integrated ML, and fine-tuning LLMs for high-stakes domains like financial trading and smart contract security.
I speak at conferences such as EthCC and NEARCON, guest-lecture at universities (including VIT-AP on production AI and LLM careers), and mentor at nonprofit hackathons like Opportunity Hack with Women in Computer Science at ASU, helping teams ship AI for real nonprofits in 24 hours.
Before DCG, I led TensorFlow CPU performance optimization at Intel, improving core operations significantly and earning the Division Achievement Award. I hold a Master's in Data Science from Northeastern University.
Welcome to my world. Grab a paddle; the AI waters are deep, and we're going swimming.

// Education
// Achievements
Achieved top-performing model status 7 times across 7 distinct tasks on the blockchain-based FLock network. Featured internationally at EthCC Brussels and in the official FLock blog interview, tweet, and YouTube segment.
Recognition for the TensorFlow Windows project, leading to Intel's ownership of the TensorFlow CPU build from Google and the first successful release for the Windows ecosystem.
// Speaking, mentoring & judging
Lightning talk on training 7B LLMs on edge devices at the NEAR Foundation conference (Fort Mason), alongside speakers from PyTorch, Gensyn, Akash Network, and Hyperbolic Labs.
Invited segment on decentralized AI and federated learning on the FLock network—how on-chain coordination and incentives change who can train models, what “production” means when compute is distributed, and lessons from shipping real federated workloads. Opens the official EthCC recording on YouTube (FLock segment).
Two-hour session for the School of Computer Science and Engineering on production AI: how LLMs are built and deployed, LoRA and QLoRA, why most models never leave the notebook, and a walkthrough of a production system from DCG.
// Publications & trade articles
This survey examines practical approaches to fine-tuning large language models under realistic hardware limitations. It covers parameter-efficient fine-tuning methods including LoRA and its variants, quantization techniques such as QLoRA and GPTQ, memory optimization strategies, and federated learning approaches for distributed training. The paper synthesizes empirical findings across these methods and proposes a decision framework for selecting appropriate configurations under varying resource constraints. Currently under peer review at PeerJ Computer Science (Q1).
This paper introduces a bidirectional B-only protocol for federated LoRA fine-tuning that tracks per-round upload and download bytes explicitly, and ReverseAdaptive, an aggregator that switches between FLoRA and FFA-LoRA based on a loss-improvement plateau signal. Experiments across TinyLlama-1.1B and LLaMA-3.2-3B show up to 40.5% measured communication savings with no measurable downstream accuracy cost on MMLU, ARC-Easy, BoolQ, and HellaSwag. Currently under peer review at Transactions on Machine Learning Research (TMLR) (OpenReview #9042).
