All Projects & Experiments

A comprehensive showcase of web platforms, open-source utilities, full-stack applications, and interactive tools.

Full Stack2025

Atlas Analytics

Self-serve product analytics with sub-second queries over billion-row events

A multi-tenant analytics platform where teams define events, build funnels, and query aggregated results without writing SQL. The interesting work was in the query layer: a columnar store, incremental rollups, and a caching strategy that kept p95 under 400ms while writes stayed continuous.

Incremental hourly rollups cut p95 query latency from 4.2s to 380ms
Virtualised data grid renders 100k rows without measurable frame drops

Developer Tool2025

Traversal

Interactive JSON inspector that renders 100k-node documents without hanging

A developer utility for exploring large JSON payloads — schema inference, path search, and a virtualised tree that stays responsive on documents far past the point where naive renderers choke.

Web Worker parsing keeps the UI at 60fps on 40MB+ documents
Windowed tree virtualisation renders 100k+ nodes smoothly

Full Stack2024

Relay

Realtime collaborative boards with conflict-free concurrent editing

A multiplayer planning tool where multiple people edit the same board simultaneously. The core problem was convergence: concurrent edits had to merge without losing work, and presence had to feel immediate rather than eventual.

Operational transform layer converges concurrent edits without data loss
Optimistic drag-and-drop reconciles against server acknowledgement

Open Source2024

Meridian Design System

Accessible React primitives adopted across four production surfaces

A component library and token pipeline shared by multiple product teams — built around strict accessibility guarantees and a theming layer that stays in sync with design.

48 primitives with keyboard and screen-reader behaviour covered by tests
Single token source generates Tailwind config and CSS custom properties

AI & Tools2024

Pulse

LSTM forecasting service with backtesting built into the interface

A time-series forecasting tool for retail demand, pairing a sequence model served behind a Python API with an interface designed around how analysts actually evaluate forecasts.

Walk-forward validation reports honest error instead of split-optimistic numbers
Interval bands expose forecast uncertainty at every horizon

Frontend2023

Ledger

Storefront rebuilt around Core Web Vitals without cutting features

A performance rebuild of a mid-sized commerce frontend — same catalogue, same checkout, but a fraction of the JavaScript and a materially better experience on slow connections.

Client JavaScript reduced by 62% through route-level splitting
Lighthouse performance moved from 54 to 97 on mobile throttling
