What I'm looking for

I'm looking to build scalable cloud-native and AI-driven products, especially high-throughput systems, RAG pipelines, and production-grade LLM agents that deliver measurable business impact.

At Biso, I build AI-driven e-commerce systems for a global SaaS platform serving 250+ brands. I architected a high-concurrency AI assistant that helped drive a 55% increase in product sales through real-time agentic workflows.

I’ve scaled data ingestion for 200+ clients with AWS Fargate and PostgreSQL, built RAG capabilities with pgvector, and implemented LLM tracing and evaluation with LangSmith and CloudWatch. I also deployed forecasting pipelines with Prophet and resilient FastAPI services on AWS Lambda and ECS with 99.9% uptime.

Previously, I delivered backend and AI integrations for UNICFC and MetLife, including fact-checking, voice detection, proctoring, and enterprise payroll APIs. At Wake Commerce, I helped refactor a legacy .NET monolith into modular, API-first microservices using CQRS, MediatR, Docker, CI/CD, and Kafka.
