Engineering Autonomous Systems & Production AI.

01 / Identity & Architecture

Taking systems from vague asks to live production.

AI engineer who builds agents that make decisions, with around two years across freelance client delivery and internships. Ships agentic systems end to end: a three-stage LLM guardrail agent packaged as an MCP plugin and adopted inside Claude Desktop, Cursor and Codex, multilingual voice agents, and full-stack AI products for 10+ clients. Comfortable owning a feature from prompt and tool design through deployment and evaluation. Looking for an early-stage team where I can build AI-native product.

Owned scoping through launch on full-stack and AI-integrated builds for 10+ clients across React/Next.js and Python/FastAPI/Flask stacks. Built an agent that raised client productivity by 60% and cut costs by 20%. Architected Sentinel, a three-stage LLM safety-guardrail agent (rules engine, self-trained classifier at 76% cross-validation accuracy, final review pass) shipped as an MCP plugin used in Claude Desktop, Cursor, and CodeX. Built an Agentic Sales Call Center on Vapi, n8n, Twilio, and Google Calendar/Sheets that reads caller intent mid-conversation and fires bookings, WhatsApp alerts, and logging.

Trained and shipped a linear regression forecasting model (scikit-learn, pandas) as lead contributor, sharpening forecast accuracy on live equity market data through iterative feature engineering. Constructed an end-to-end data pipeline covering ingestion, cleaning, and feature preparation that fed the model into a live Flask dashboard used for daily decision-making. Automated manual back-office workflows with custom Python and Flask scripts, shrinking processing time by 40% across a multi-person operations team. Presented technical trade-offs and solution design directly to internal stakeholders, backing recommendations with clear, data-driven reporting.
