Things I’ve
put into the world.
Financial data pipelines, business platforms, and independent experiments. A selection of the systems I’ve worked on.
Nexius AI
A production SaaS platform that turns raw financial documents into structured, auditable data through an OCR-to-LLM pipeline: parsing, extraction, validation, journal mapping, report generation, and delivery.
FastAPI / Python / MongoDB / RabbitMQ / OCR / SSE
Engineering notes
- Designed a modular OCR and document-processing pipeline: parsing, normalization, feature extraction, validation, transaction mapping, and report generation.
- Built backend services connecting document ingestion, background workers, structured output generation, user review flows, real-time progress events, and queue-based AI processing.
- Built ambiguous-transaction clustering and a Weighted Purity evaluator that scores clustering quality with size-weighted purity and outlier penalties, keeping automated categorization honest at scale.
- Improved observability with OpenTelemetry, SigNoz, structured logs, queue diagnostics, and progress snapshots so a distributed async pipeline stays debuggable in production.
