Reliable tools for cloud-scale engineering.

Go / TimescaleDB / React / Python / AWS

Built and deployed a real-time telemetry platform for a physics STM cryogenic lab, ingesting live instrument data through a Python edge collector into a Go API and TimescaleDB backend. The system adds public dashboards, CSV export, threshold email alerts, remote sampling control, offline buffering, and reliability checks across restart and network-failure scenarios.

Next.js / FastAPI / PostgreSQL / Qdrant / OpenAI

Built an enterprise knowledge assistant with RAG over PDFs, Markdown, and internal documentation. The platform combines document ingestion, vector search, citation-backed answers, feedback loops, and evaluation metrics so teams can inspect both what the copilot says and why it found that context.

Kubernetes / Prometheus / Grafana / Kafka / Python

Designed a production-style observability stack for containerized microservices: Prometheus and Grafana for service health, Kafka for metric and alert streams, Python workers for anomaly detection and incident classification, and PostgreSQL for durable operational history.

TypeScript / Node.js / MCP / Google OAuth

Built an open-source Model Context Protocol server that lets AI agents search, read, create, and update Google Docs through secure OAuth-backed tool calls. I designed dry-run previews, validation paths, and stdio transport so agents can inspect intent before touching real documents.

React Native / Expo / Node.js / Express / SQLite

Built a salon membership management system with a Node/Express/SQLite backend and a React Native Expo mobile app. The product covers member registration and editing, stored balance and membership tiers, transaction history, staff and service management, dashboard metrics, and an iPad kiosk registration flow.

Node.js / GraphQL / React

At Oracle Cloud Infrastructure, I worked on an internal portal that turned scattered backend operations into a clearer path for engineers: GraphQL over existing services, richer debugging signals, and a smoother onboarding flow.

Python / AWS / Terraform

Designed automation around infrastructure lifecycle work so teams could provision, validate, and tear down cloud environments with less handholding and fewer fragile manual steps.

Java / Spring Boot / JavaFX / Algorithms

Built a production-style course scheduling system that searches across 10,000+ course and section combinations with hard constraints, soft preference scoring, multithreaded pruning, Dijkstra campus travel modeling, a Spring Boot REST API, JavaFX client, Flyway migrations, and native iCalendar export.

JavaScript / Python / Deterministic Evals / Agent Benchmarks

Built a determinism-first evaluation framework for long-horizon LLM agents: agents write policies in a sandbox, then Gauntlet re-scores those policies on secret held-out seeds inside a pinned canonical arena. The framework separates a zero-dependency JavaScript environment layer from a Python eval layer, with tamper checks, crash recovery, baselines, and reproducible cohort analysis.

JavaScript / Python / LLM Evaluation / Roguelike Benchmark

Built the pilot infrastructure for measuring how LLM agents play a deterministic roguelike shooter. The system ports the game into a headless black-box environment, enforces train and held-out seed splits, captures JSONL traces, audits sandbox integrity, compares policy-coding against direct-play, and reports negative results honestly instead of optimizing for a flashy bot.

Python / RAG / Retrieval Evaluation / LLM Judge

Rebuilt a documentation-QA RAG system around evaluation as the primary artifact: local embeddings, hybrid retrieval, corpus repair, claim-coverage metrics, base-vs-RAG ablations, bootstrap confidence intervals, and full judge traces. The project surfaces where naive RAG hurts, where fallback RAG helps, and when corpus gaps are the real ceiling.

SystemVerilog / UVM / SVA / Python / Makefile

Built a reusable UVM verification environment for a parameterized FIFO/peripheral-style RTL block, including driver, monitor, sequencer, scoreboard, agent, assertions, functional coverage, a verification plan, and Python-driven regression orchestration.

SystemVerilog / Verilog / Python / OpenCV / SVA

Verified a streaming image filtering accelerator with SystemVerilog testbenches and a Python/OpenCV golden model, covering boundary pixels, padding, saturation, reset timing, invalid input sequences, and stall behavior.

SystemVerilog / Verilog / SVA / Python

Developed a SystemVerilog verification environment for a memory arbiter/cache-controller style block, with protocol assertions, randomized access pattern generation, read/write ordering checks, address alignment checks, and coverage-driven closure planning.

WeChat Mini Game / JavaScript / Canvas

A WeChat mini game I built to explore how tight touch controls, roguelike upgrade choices, persistent talents, item drops, and multi-phase Boss behavior can fit inside a lightweight canvas runtime.

Next.js / React / Narrative Systems

A branching narrative prototype focused on stateful storytelling: choices change stats, hidden clues unlock routes, and the interface keeps the story readable while the system tracks consequences.
