I am an AI Engineer with 3 years of industry experience building production computer vision systems, generative AI pipelines, and automation workflows. I do not do experiments — I ship working systems.
At SpectrifyAI, I built and deployed YOLOv8-based quality inspection systems that improved detection accuracy from 68% to 84% on real factory floors. At Syntrixal, I architect end-to-end AI SaaS products, from data pipelines and LLM integrations to front-end interfaces. I also deliver independent freelance projects in computer vision and generative AI, including custom ComfyUI workflows and LoRA training.
What I build:
- Real-time object detection and tracking (YOLOv8/v10, OpenCV)
- Custom ComfyUI/FLUX/SDXL generation workflows
- LoRA checkpoint training for consistent product/character output
- FastAPI inference APIs and Dockerized microservices
- AI agent workflows and automation systems (n8n, Python)
I work independently, I work fast, and I focus on results that hold up in production — not demos that break in the real world.
If you need an AI engineer who can take a concept and ship a working system, let's talk.
I’ve generated $1M+ in revenue for clients through SaaS platforms and Chrome Extensions, and I’ve solved complex automation challenges where 20+ developers previously failed.
With 150+ clients served and 250+ real-world projects shipped, I build production-ready software that solves real business problems, not just demos.
