Hi — I'm Josiel Hernández. I build performant web platforms across the stack, from shipping Shopify at scale to shaping component systems for enterprise clients like Comcast, Santander, and JM Family. Currently leaning into fullstack work, coffee, and the craft of thoughtful interfaces.
I'm Josiel — a software engineer who loves the quiet corners of the craft: clean state, thoughtful components, and interfaces that feel honest.
Lately I've been going deep on fullstack — shaping APIs, wiring headless commerce, and shipping UI systems that scale. I care about the last 10%: the easing curve, the loading skeleton, the micro-copy on an empty state.
Outside the editor: coffee, challenging briefs, and side projects that teach me something new.
Serverless rate aggregation with Step Functions orchestrating carrier calls, durable pricing state in DynamoDB, and containerized APIs on ECS/Fargate — all provisioned with Terraform and covered by unit + E2E tests.
