I help companies design and deploy production-grade AI systems — fast, reliably, and with domain precision.
With 15+ years of experience as a founder and builder, I’ve led end-to-end delivery of AI-first SaaS platforms across industries. I co-founded CropIn (AgTech), and since then, my focus has been on high-impact solutions in construction tech, e-commerce, recruitment automation, and enterprise productivity.

Drive multi-system integration with tools like Procore, ERPs, ATS, Google Suite, and APIs
✅ Product Strategy & Lean Execution
Run rapid product discovery sprints to validate what to build — before writing a line of code
Shape early product direction through use case mapping, user interviews, and iterative prototyping
Help founders build and scale lean product teams — from first hires to cross-functional pods
Define MVP scope, GTM loops, and internal tooling priorities with clear logic and speed
🛠️ Core Skill Areas

Whether it's a complex Generative AI model or a classic predictive algorithm, a model is only valuable when it's reliably working in production. I architect and build the robust, scalable, and cost-effective systems that turn machine learning potential into measurable business impact.
As an Expert-Vetted (Top 1%) AI/ML Architect with over 15 years in enterprise systems, I specialize in solving the critical "last-mile" problem: making machine learning work in the real world.
My focus is on helping businesses like yours:
🚀 Productionize Your Full ML Portfolio: I take your models—from classic predictive algorithms to complex LLMs—out of the notebook and into production. I design and deploy the high-availability cloud infrastructure (AWS, GCP, Azure) needed to make them performant and reliable.
💰 Optimize Cloud Costs Across All Models: ML can be expensive. I audit your complete ML infrastructure to identify and eliminate wasteful spending on both training and inference. My goal is to maximize your ROI on every model you run.
⚙️ Implement Robust MLOps Frameworks: I build automated CI/CD/CT (Continuous Integration/Delivery/Training) pipelines for your entire ML lifecycle. This ensures governance, reduces manual error, and allows your data science team to iterate and deploy new models faster and more safely.
Why Choose Me?
I provide a rare combination of full-spectrum ML knowledge and battle-tested engineering discipline.
⭐ Expert-Vetted by Upwork: Formally recognized as being in the top 1% of talent on this platform.
⭐ Full-Spectrum ML Expertise: My specialization in Generative AI is built on a deep, 9+ year foundation in traditional Machine Learning (from classification to forecasting) and Data Science. I don't just follow the latest trends; I understand the entire landscape.
⭐ 15+ Years of Architecture Experience: My background ensures your ML system is not just a model, but a well-engineered, maintainable, and secure component of your business.
⭐ PMP® & SAFe® Certified: I manage projects with professional discipline, ensuring clear communication, on-time delivery, and a sharp focus on your business goals.

Expert-Vetted on Upwork (Top 1%).
Fractional CTO and AI engineer. 15+ years building search systems, ML platforms, credit engines, and recommendation systems across biotech, fintech, and martech.
The implementation layer is getting cheaper every quarter. Judgment about what to build, when, and with what tradeoffs has gotten more valuable. That's where most of my time goes now.
𝗪𝗵𝗮𝘁 𝗜 𝗱𝗼
• Help you decide what's worth building
• Help you scope it without painting yourself into a corner
• Take the technical side off your plate for a while
𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸
• I'll tell you not to build it if it's not worth building
• I push back, and I expect you to push back on me
• I take responsibility, and I expect the authority that goes with it
𝗦𝗲𝗹𝗲𝗰𝘁𝗲𝗱 𝘄𝗼𝗿𝗸
• Medical-legal document extraction. Owned architecture, build, and the calls about what to automate vs leave to humans. Weeks of analyst review compressed to minutes. The interesting problems weren't the AI ones.
• Scientific AI platform for biotech R&D. Took a working PoC to a system the team actually relies on. Parser reliability, confidence calibration, CI/CD benchmarking.
• AI-assisted event marketplace. Backend architecture, payments, AI planning assistant.
• Domain-adapted speech recognition for spacecraft operations. Real-time voice-loop capture, indexed searchable transcripts, deployed across multiple missions.
• Personalized footwear production pipeline. Parametric CAD + automated manufacturing instructions. 2 days → 30 minutes per pair. Made the unit economics work.
𝗘𝗻𝗴𝗮𝗴𝗲𝗺𝗲𝗻𝘁𝘀
• Initial Fit Call — free. 30-min call + follow-up memo with 2–3 ranked next steps.
• AI Product Audit & Roadmap — from $7k, ~2 weeks. Pressure-test scope, architecture, stack, failure modes, team shape.
• Fractional CTO — custom, usually 10–20 hrs/week for 3–6 months. I own architecture, technical direction, and execution quality.
Stack often includes: Python/FastAPI, TypeScript/React/Next, Postgres, GCP/AWS, OpenAI/Anthropic, RAG, vector search.
