Created a reliability-focused MySQL toolkit covering replication checks, backup and restore drills, and operational validation with clear guardrails. This project demonstrates my production mindset around database reliability, recovery confidence, and safer operations.

Built a real-time AI interaction architecture using streaming patterns, session-aware communication, lightweight retrieval, and observability-first design. This work highlights my approach to production-minded AI systems where latency, traceability, and reliability matter.

Designed a practical LLMOps / RAG foundation for grounded AI workflows, with structured ingestion, retrieval, testing, and cloud-ready extensibility. This project reflects how I approach applied AI systems with engineering discipline, not just prototype-level experimentation.

Built a production-oriented GPU platform on AWS EKS with a strong focus on security, observability, progressive delivery, and cost-aware scaling. This case study shows how I design cloud foundations for AI workloads using Kubernetes, GitOps, policy guardrails, and platform automation.

--- DESCRIPTION (long) --------------------------------------------
Chacaltaya is a quiet station built on Zo Computer. Visitors ask one question and receive a single, signed reading: one interpretation, one risk, one next honest move.
They can file the reading for the record by entering an email. The site enqueues an outbox entry and a Zo automation fulfills the request using the connected Gmail integration (sends a plain-text copy to the visitor) and the Google Drive integration (archives the same reading as a .txt file in a station folder). Every step writes a restrained entry to the public station log, with no leak of personal data.
Completing a four-stage ascent unlocks a second pass of the Hidden Frequency — a genuine additional transmission, not a badge or a score. Open hours are driven by a Google Calendar integration seam. Payment is handled via a Stripe test checkout that redirects to a station-voice thanks page.
Built with Bun + Hono + React on Zo hosting.
