Work Experience
Senior Full-stack AI Engineer
Online Freelance Agency
- Built AI agent workflows to automate document and email processing, reducing manual processing time from 15 – 20 minutes to approximately one minute across multi-country operations.
- Designed and deployed RAG-based LLM systems, enabling semantic search over enterprise documents, improving answer accuracy, and reducing manual lookup effort.
- Implemented hybrid retrieval pipelines using BM25 and vector search with evaluation and guardrails to minimize hallucinations and improve response reliability in production.
- Developed scalable AI APIs using Python and FastAPI, integrating Azure OpenAI and vector databases for real-time enterprise decision support.
Experience
Enterprise RAG AI Assistant with Agent Automation
I implemented evaluation pipelines and guardrails to reduce hallucinations and ensure reliable outputs. I also built scalable APIs using Python and FastAPI, integrated Azure OpenAI and Azure AI Search, and deployed using Docker with CI/CD pipelines. The platform reduced manual processing time from 15 – 20 minutes to approximately one minute and enabled consistent, auditable AI-assisted decision-making across business workflows.
Legal Intelligent Assistant — Enterprise AI Contract Platform
As a full-stack AI developer, I designed a multi-agent RAG system where a router agent classifies queries and delegates to specialized Delegation of Authority (DOA) or contract agents with strict source-only guardrails. I implemented real-time streaming chat via Server-Sent Events, a DocuSign JWT Bearer Grant integration that auto-ingests signed envelopes through webhooks, and an intelligent feedback loop where negative feedback triggers AI regeneration, admin email approval, and curated Q&A injection into future prompts. I also integrated Okta SSO alongside Azure AD, built automated SharePoint policy sync, and enforced enterprise security via Azure Key Vault, RBAC, and HMAC-verified webhooks.
Enterprise AI Receipt Reader for Airline Flight Disruption Claims
AI-powered Log Intelligence & Auto-remediation Platform
Phase 1 — Log Intelligence: CSV ingestion, Polars normalization, 7-day baselines, 6-rule anomaly detection, incident grouping, evidence-based root cause, and AI narrative. Outputs delivered via FastAPI, React dashboard, and Teams/Email/Slack alerts.
Phase 2 — AI Auto-Remediation: a Claude Code agent receives validated incidents, analyzes the codebase, implements fixes on feature branches, runs tests, and opens PRs for human approval with triage gate, scope resolver, and fix-history audit rail for governance.
