Work Experience
Senior AI Engineer & Full-stack Developer
Creole Studios
- Engineered a LangGraph multi-agent learning platform with context-aware routing, long-term memory, GraphRAG, VAPI voice, and real-time digital avatar interactions.
- Built a FastAPI and LangGraph accounting agent using Google ADK, supervisor-worker routing, MongoDB tools, PDF mapping, and Pydantic self-correction loops.
- Developed an autonomous voice agent using Twilio, OpenAI Realtime, WebSockets, BullMQ, Redis, and Whisper, with automated CRM logging and calendar booking.
- Delivered a multi-tenant voice AI platform supporting up to 20 tenants through isolated webhook routes, tenant-specific instructions, and shared AWS infrastructure.
- Created a Python 3.12 and FastAPI support platform with tenant-scoped PostgreSQL access, HMAC API keys, short-lived JWTs, and Redis rate limits of 10 and 1,000 per hour.
- Built an AI visual-search pipeline using FashionCLIP and Pinecone, generating 512-dimensional embeddings and processing catalog batches of more than 100 items.
- Integrated Amazon Bedrock and Textract to classify, extract, and query aviation records across millions of document pages through natural-language search workflows.
- Secured a healthcare SaaS using Supabase Auth, PostgreSQL RLS, role-based access, protected APIs, and controlled handling of sensitive patient data across AI and clinical workflows.
- Built human-in-the-loop and tool-level guardrails for agentic AI workflows, keeping high-risk actions reviewable and preventing agents from directly executing sensitive operations.
- Designed tenant-isolated voice AI workflows with separate webhook routes, controlled tenant instructions, protected recordings, and presigned S3 access for sensitive call data.
Senior Full-stack & Cloud Engineer
Creole Studios
- Architected a NestJS and TypeScript back end with Prisma and PostgreSQL, supported by BullMQ, Redis, and AWS Lambda for distributed crawling and scheduled processing.
- Designed a serverless AWS platform using Lambda, API Gateway, EventBridge, SQS, DynamoDB, and Cognito, including a three-stage ingestion and processing pipeline.
- Built scalable Next.js applications with protected routing, server-side rendering, reusable state providers, structured API handling, and data-intensive user interfaces.
- Developed transaction-focused workflows with guarded state changes, audit history, complex financial calculations, and PostgreSQL-backed ledger processing.
- Implemented scheduling and payment workflows using Supabase Edge Functions, a 12-factor matching engine, and Stripe, Braintree, and PayPal integrations.
- Established monorepo standards with Turborepo and pnpm, shared TypeScript packages, Dockerized services, GitHub Actions, Sentry monitoring, and code-quality checks.
- Built a secure multi-tenant SaaS back end with HMAC-hashed API keys, short-lived JWTs, database-level tenant isolation, rate limiting, tenant-specific CORS, and audit logging.
- Improved API and webhook security across production integrations by validating signatures, limiting access, protecting secrets, and keeping sensitive data out of client-side flows and logs.
- Built financial workflows with strict transaction validation, role-based access, and an auditable chain-of-title to prevent invalid ownership transfers and maintain transaction integrity.
- Secured organization-level access to aviation records using Cognito, NextAuth, private S3 storage, and controlled document access across a large document intelligence platform.
