At KHGC Software Company Limited, I take full-stack client-platform features from discovery through production, using React.js and Next.js, Node.js and Python, and PostgreSQL. I also help ship RAG-based search and in-app assistants with human review and evaluation.

On Climatebase, I built interfaces for job search, employer dashboards, and applicant profiles, and implemented Elasticsearch-backed search and filtering. I also designed PostgreSQL schemas for the fellowship application pipeline.

For Assembly, I built the client-portal dashboard and REST and GraphQL APIs, and designed data schemas for multi-tenant client and billing information. I provisioned AWS environments with Terraform and implemented secure document sharing and in-app messaging.

As a freelance software engineer, I’ve delivered full-stack products for clients in North America and Europe, often working independently from discovery through delivery. I enjoy clarifying ambiguous problems, proposing an approach, and following it through to production while helping other engineers raise the quality of their work.
