Turn Business Data into Measurable Value with Practical AI/ML Systems
I help growing companies turn existing data into better forecasts, smarter decisions, and working AI products — from identifying the opportunity and building the models to deploying systems that deliver results.
What I Help With
Forecasting & Predictive Modeling
Anticipate demand, operational risk, and rare events with models evaluated against real-world outcomes.
Decision Science & Optimization
Turn forecasts and business constraints into better pricing, inventory, prioritization, and resource-allocation decisions.
AI Search, RAG & Hybrid Retrieval
Make complex document collections searchable using semantic retrieval, BM25 keyword search, reranking, and grounded AI workflows.
Production ML & AI Systems
Build reliable data, modeling, monitoring, and retraining workflows that work beyond the prototype stage.
Why This Matters
Successful AI/ML projects begin with a business problem, not a technology. Whether the goal is improving profitability, managing operational risk, or making existing information more useful, the challenge is connecting analytical capabilities to real decisions. I bring both business and technical experience to that process—from working with imperfect data and defining meaningful objectives to building systems that teams can adopt and sustain.
Featured Work
Pricing & Optimization Systems
At Thrasio, I developed production pricing and inventory decision systems combining demand forecasting, price elasticity, and financial constraints. An inventory-aware pricing initiative increased profitability by 15% while reducing excess inventory by 20%. Separate elasticity work covered 10,000+ products.
Predicting Housing Complaints Before They Occur
Client Engagement · Kogan AI Consulting
Built a quarterly housing complaint-risk system using NYC housing data across buildings, apartments, and 13 complaint categories. A retrospective evaluation of roughly 7 million previously generated scores found that the highest-risk 10% had 6.3× the overall complaint rate—providing a strong signal for identifying units that may warrant earlier attention.
RAG & Hybrid Search Product
Developed and evaluated document retrieval for a collection of approximately 10,000 documents, benchmarking three embedding models. The implemented retrieval system combines BM25 keyword search, semantic vector search, reciprocal rank fusion, and reranking to surface relevant passages and their source context.
Ways to Work Together
Project-Based AI/ML Consulting
Build or improve a defined forecasting, optimization, retrieval, or production ML system — with clear deliverables and evaluation criteria.
Technical Audit & Advisory
Get an independent assessment of data readiness, model quality, RAG performance, technical risks, or the next step for an existing prototype.
Fractional AI/ML Leadership
Get senior technical direction on strategy, architecture, validation, and delivery without a full-time AI/ML leadership hire.
About
I’m Isroel Kogan, an AI/ML engineer and consultant with experience spanning pricing and inventory optimization at Thrasio and production ML and AI search at Cadmus. Through Kogan AI Consulting, I bring business-focused modeling and hands-on engineering together to help teams build useful systems from their data.
