I own the entire stack. Frontend architecture, backend services, databases, CI/CD, deployment. I've shipped CRM platforms, real-time collaborative editors, chat systems over WebSockets, and marketing sites on Cloudflare Workers + KV.

I think in systems, not features. Database schemas, CRDT conflict resolution, CI/CD pipelines, caching strategies. I read DDIA and OSTEP for fun and I believe the best UI is backed by the best architecture.

• Contributed to building planning, execution flows, and user-driven workflow features
• Worked with rapidly evolving product requirements, requiring fast iteration, clean abstractions, and pragmatic engineering decisions

Learning: How to balance speed with maintainability in an early-stage environment, and how engineering decisions directly shape product velocity and user trust.

San Francisco, USA

• Built landing pages, waitlist flows, and core UI for an AI-driven product

[live] · [github]

• Collaborative document editor built on livetexts — no accounts, no sign-up
• Create a doc, share a join code, write together in real time with live colored cursors
• Offline-first: edits survive tab closes and dropped connections via IndexedDB + Yjs CRDT sync
• One-click publish to a public URL — anyone can read it, no login required
• Stack: Next.js, TypeScript, Yjs, TipTap, Cloudflare Workers

Why this matters: Built to understand how production sync services like Liveblocks actually work — from the CRDT math to the Durable Object architecture. Deep systems thinking shipped as a real product.

[npm] · [github]

• Open-source npm package for real-time collaborative rooms — presence, CRDT storage, collaborative text, and offline sync
• One Durable Object per room on Cloudflare Workers — the same architecture Liveblocks runs in production
• Yjs CRDT with bidirectional state-vector sync for lossless offline merge across tab closes and dropped connections
• JWT auth signed locally — no round-trip to a central auth service. Zero idle cost via WebSocket hibernation
• Stack: Cloudflare Workers, Durable Objects, Yjs, SQLite, TypeScript

Why this matters: Self-hostable means you own your infrastructure, your data, and your costs. The same real-time primitives Liveblocks sells — without the vendor lock-in.

[live] · [github]

• Reference Next.js app demonstrating a full livetexts integration end-to-end
• Collaborative text editor with live presence sidebar, real-time sync, and full JWT auth flow
• Shows room creation API, Yjs CRDT binding, and WebSocket connection lifecycle in practice
• Stack: Next.js, TypeScript, livetexts, Yjs, Tailwind CSS

[github]

• Implemented both op-based and state-based CRDTs from the foundational academic paper
• Built from scratch to deeply understand the concepts behind conflict-free data structures before building livetexts
• Stack: TypeScript

[live]

• Chat-based AI interface that generates workflows across connected apps (Gmail, Outlook, spreadsheets)
• Translated multi-screen product flows into interactive, production-like prototypes
• Stack: Next.js, Composio, Express.js, Tailwind CSS

[demo on loom]

• GitHub App that automatically reviews PRs and responds to developer @mentions with actionable, contextual feedback
• Generates structured diffs, sends them through an AI review pipeline, and posts comments directly on GitHub
• Owned end-to-end — system design, webhook handling (Probot), diff generation, AI integration, and developer-facing feedback loops
• Reduced review turnaround time, improved code consistency, and boosted productivity for early-stage teams
• Stack: GitHub Apps, Probot, Node.js

Why this matters: Built to solve a pain point I experienced myself as a developer. Code review is a bottleneck — this automates the tedious parts so humans can focus on the design decisions.
