01 / Focus

From robust APIs to production-ready AI.

Backend

Reliable APIs, maintainable service boundaries, and asynchronous workflows built with Python, FastAPI, and Django.

Cloud

Cloud-native workloads on AWS, supported by PostgreSQL, Docker, Terraform, and pragmatic reliability practices.

Applied AI

AI-enabled applications that bring RAG, LLM integrations, and agent-based workflows into real product systems.

02 / Work

Selected projects.

drayage-watch

FastAPI · PostGIS · OR-Tools · OSRM · React

Public portfolio demo modeling carrier and terminal charge exposure for drayage dispatch teams: a framework-independent, versioned tariff engine; OR-Tools dispatch optimization over OSRM-routed truck fleets; and a React/Leaflet interface, backed by automated API and frontend build tests in GitHub Actions.

Uses synthetic fleet data and cited/illustrative tariff snapshots — a portfolio demo, not a production system.

route-planner

React · Vite · OSRM · FastAPI · Leaflet

Public portfolio demo that turns an Excel/CSV list of stops into a delivery order: OSRM-based route solving, per-stop ETAs and time-window alerts, and Excel export. A strict core/adapters boundary keeps routing logic framework- and transport-independent, with an optional FastAPI layer and a reproducible self-hosted OSRM build behind the same contracts.

Single-vehicle scope, no CI configured yet — active development, not a production system.
