Hello! I'm
Antonio West
Full-stack and AI systems engineer. Building production web applications, offline-first client architecture, and deterministic LLM pipelines across Next.js, TypeScript, and PostgreSQL.
Production Systems
Deterministic web apps, offline client storage, and guarded LLM pipelines.
Client Systems & Architecture
Document Parsing & Personalised Coaching Pipeline
Automated text extraction from multi-page PDF & DOCX uploads using pdfjs-dist and mammoth to eliminate manual data entry. Built a 23-step dynamic onboarding state machine with localStorage session recovery, strict JSON schema validation, and automated GPT-4o output regeneration.
Meeting Audio Summarisation & Intelligence Engine
End-to-end meeting intelligence pipeline for ChatSDK ingesting Whereby recordings through a multi-provider LLM summarisation layer. Built background workers with intelligent transcript caching and polling, persisting structured action items directly to PostgreSQL via Drizzle ORM.
Veribite
Sub-Second Allergen Detection for Complex Grocery Labels
Built to remove the risk of human fatigue when checking packaging labels in busy supermarkets. Shoppers scan a barcode to get an immediate, deterministic safety verdict against their specific allergens from a local cache of 70,000+ UK products, avoiding manual label audits with zero network latency.
Personalised Dashboard
Weekly shopping summary, quick barcode scanner, and live allergen scan history.
Systems & Benchmarks
Molecular Toxicity & Property ML Pipeline
High-throughput machine learning pipeline predicting molecular properties and compound toxicity with TreeSHAP explainability and partitioned Parquet data streaming via PyArrow for memory efficiency.
WebGL Shader & Texture Memory Optimizer
Client-side utility that packs discrete PBR material channels (Roughness, Metallic, AO, Height) into single 32-bit RGBA textures, cutting browser VRAM footprint by up to 75% while locking rendering at 60 FPS.
