Programmatic Ad Pipleline Optimization
The Challenge
Legacy processing pipeline was taking 14+ hours, frequently missing internal SLAs and causing revenue attribution delays.
The Solution
Re-architected the entire flow using AWS Batch for parallel processing and optimized Snowflake merge logic to reduce lock contention.
The Impact
Reduced runtime to ~5 hours (60% improvement) and cut compute costs by 30% by moving off always-on instances.

Enterprise Data Quality Framework
The Challenge
Manual data validation across 15+ brands led to silent failures and bad data entering executive dashboards.
The Solution
Built a serverless validation framework (AWS Lambda) with AI-generated rules that syncs bidirectional with Google Sheets for non-tech users.
The Impact
Eliminated manual QA time by 100% and caught 50+ critical data issues in the first month before they reached production.

GOAT - Gartner's Own Agentic Tech
The Challenge
Gartner associates needed quick access to client information, engagement data, and research materials but relied on fragmented internal tools.
The Solution
Built GOAT, a conversational agentic AI assistant with RAG pipelines, multi-agent orchestration, and re-architected infrastructure from AWS EKS to serverless Lambda.
The Impact
Serving 5,000+ concurrent users with 88% query resolution improvement, 35% infrastructure cost reduction, and 40% token efficiency via A/B testing.

Soul Mesh - Distributed Compute Network
The Challenge
Multiple low-powered devices (Raspberry Pi, old PCs) sitting idle while cloud GPU costs for LLM inference are prohibitive.
The Solution
Built a distributed compute mesh that combines multiple devices into one virtual machine using hub-agent model with WebSocket heartbeats, JWT auth, and mDNS discovery.
The Impact
v0.2.0 with 253 tests passing, live-tested across 2 devices. Enables local LLM inference without cloud costs.

Soul Outreach - AI Marketing Pipeline
The Challenge
Manual outreach workflows — finding contacts, researching them, drafting personalized messages — take hours per prospect and do not scale.
The Solution
Building a CLI pipeline that automates the full outreach flow: import contacts, enrich with AI research, draft personalized messages, and send — all from the terminal.
The Impact
End-to-end automation of outreach workflows, from contact import to personalized message delivery.
