70+ Active B2B Clients in Q1

Case Management Hub (SaaS Platform)

Architected and led the full-stack development of a highly scalable, multi-tenant enterprise SaaS platform from scratch. Engineered secure backend infrastructure using NestJS with a hybrid database model (MySQL + MongoDB) for strict data isolation. Implemented rigorous HIPAA compliance protocols, end-to-end data encryption, and granular RBAC. Successfully onboarded 70+ active high-paying B2B clients within the first quarter.

Autonomous AI Job-Scraping & Data Pipeline

Architected an automated n8n data harvesting pipeline, initially built with a 5-node OpenAI (GPT-5 Mini) architecture. Optimized API costs and latency by migrating to local LLM infrastructure running qwen3.6:35b via Ollama on an M4 Pro (48GB RAM). Engineered a secure, low-latency reverse tunnel using bore.pub to expose the local model endpoint directly to the cloud n8n instance. The pipeline autonomously aggregates, parses, and matures multi-source unstructured web streams into high-fidelity structured datasets.
