I build private production systems end to end: product strategy, interface architecture, geospatial data planes, Rust API platforms, database governance, cache/search layers, security boundaries, media pipelines, DevOps observability, and AI-assisted delivery as one operating system.
The public repositories are selected artifacts from that practice. The deeper work lives in private integrated systems: multi-surface products with public UX, dedicated admin operations, typed contracts, role-governed security, privacy-aware analytics, deployment discipline, and internal tooling that lets a solo operation behave like a serious engineering organization.
| Area | What it includes |
|---|---|
| Private product systems | Public UX, admin operations, canonical archives, profile/social layers, reputation, commerce, media, moderation, and workflow design. |
| Data and API platforms | Rust/Axum services, PostgreSQL schemas, SQLx migrations, OpenAPI/Hurl contracts, GraphQL Experience API planning, read models, search vectors, and audit ledgers. |
| Map and cache architecture | Viewport/bbox/zoom request design, approximate-location privacy, clustering, Redis-style cache keys, stale-while-revalidate, ETags, and request coalescing. |
| Frontend architecture | Next.js, React, TypeScript, SSR/RSC, SEO metadata, Mapbox/WebGL, capability-based motion runtime, design systems, typed data access, and accessibility. |
| Security and governance | Auth/RBAC, role matrices, WebAuthn/passkeys, step-up verification, separated admin surfaces, high-privilege guardrails, non-enumerating policy, and audit evidence. |
| Operations and verification | Vercel, Railway, Docker, manual CI gates, Sentry, privacy-safe PostHog, NDJSON logs, diagnostic CLIs, Vitest, Playwright, Rust tests, Hurl, and mobile QA. |
| Media and research systems | Object storage boundaries, image/video compression, YouTube/content workflows, dictionary tools, translation, EPUB/archive processing, and structured research systems. |
| AI and Vibe Coding systems | PM -> architecture -> execution plans, Codex workflows, Vibe Coding Skills, agent instructions, repo automation, and multi-session handoff systems. |
| Public artifacts | Small utilities, development environments, monitoring tools, repair scripts, and configuration repos that are safe to publish. |
