ABOUT ME

Lead iOS & AI Engineer | Expert in ComfyUI, LLMs & AI Integration

I turn builders into agentic engineers who ship faster, smarter, and with confidence—one-on-one.

WHAT I TEACH
• Agentic engineering fundamentals: design, orchestration, and evaluation of AI agents
• AI-assisted development: coding workflows that 2–5x velocity without sacrificing quality
• Generative AI: local and cloud image/video generation, diffusion models, and end-to-end pipelines
• Complex automated workflows: retrieval, tools, function-calling, evaluators, and monitoring
• Prompt engineering that scales: patterns, guards, and reproducibility
• Efficiency playbook: from Cursor/Copilot prompts to claude code, opencode, amp, repoprompt, CI, telemetry, and test harnesses.

WHY ME
• 13+ years building production apps across startups and Uber-scale systems
• 2 years hands-on in generative AI, local and cloud-hosted LLMs and image generation, prompt engineering, and automations
• I focus exclusively on 1:1 teaching—no cohorts, no fluff, just outcomes

HOW 1:1 WORKS
• Personalized roadmap tailored to your product, stack, and constraints
• Live build-and-architect sessions focused on your real projects
• Fast async support for quick questions and advice between sessions
• Project planning, code reviews, and architecture critiques
• Developer experience upgrades: templates, dev tools, CI, prompts, and guardrails
• Curated resources and practical exercises to lock in skills

OUTCOMES YOU’LL GET
• Ship agentic features in days, not months
• Choose the right approaches for your use case and budget
• Stand up local and cloud image/video generation with reproducible results
• Automate complex multi-step workflows with evaluation and monitoring
• Write prompts and system designs that survive real users

WHO THIS IS FOR
• Engineers and founders who want hands-on guidance, not theory
• Teams ready to integrate AI into production with confidence
