WORK HISTORY
Founding Software Engineer (Data) @Appsatile Ltd
Gateshead, GB
Data Architecture & Platform Engineering:• Architected 7-layer composable data system (T1-T2 storage, L1-L6 semantic layers) enabling cross-app interoperability with type safety, versioning, and tenant isolation across Platform/Studio/Business lenses• Designed cell-based multi-tenancy combining shared resources with Row-Level Security (RLS) for standard tenants and dedicated cells for enterprise; implemented 3-tier caching (Caffeine/Redis/PostgreSQL) achieving sub-millisecond latency• Built Master Data Management platform in Go with fuzzy matching, golden record merging, and multi-source ingestion (PostgreSQL, NATS JetStream, Redis, MinIO)🤖 AI & Data Governance:• Built RAG system for internal docs using ChromaDB + Ollama LLMs with auto-indexing, smart chunking, and semantic search; deployed as MCP server with REST API• Established comprehensive data governance: classification, retention policies, field-level masking, record-level access controls supporting AI training workflows Complex Data Migration:• Engineered PropertyCMS (FastAPI + Next.js) with dynamic entity framework allowing runtime creation via JSONB schemas• Designed migration scripts consolidating corrupt legacy database (165 properties, 8,395 expenses) with safe replay mechanisms preventing VBA crashes Cloud Infrastructure & DevOps:• Deployed production Kubernetes (K3s) on AWS with Keycloak OAuth, Kafka, observability stack (Prometheus + Grafana); automated with Helm/Kustomize Technical Leadership:• Authored 20+ page platform specification with PlantUML diagrams, ADRs, workspace isolation principles• Led 5-dev team establishing standards: code review, API versioning, structured logging, 24/7 runbooks
