Hi, I'm TJ Sweet
Principal / Staff Software Engineer focused on AI infrastructure, databases, open source systems, and enterprise platforms.
I build infrastructure other engineers build on: graph/vector databases, high-performance UI platforms, Web Components, telemetry tooling, developer frameworks, and production systems that need to be fast, reliable, and maintainable.
---
What I work on
- AI infrastructure for agentic systems, Graph-RAG, long-horizon memory, embeddings, local LLM inference, and retrieval platforms
- Graph, vector, and temporal database systems with API-compatible surfaces and production-grade execution paths
- Enterprise UI architecture with Angular, React, Web Components, Shadow DOM, and cross-framework design systems
- Cloud-native platforms using Go, Rust, TypeScript, Python, Kubernetes, GCP, Azure, AWS, and observability tooling
- Open source platforms, developer tools, framework migrations, and systems other engineers rely on
Engineering principles
- Build boring, reliable foundations that scale beyond the first use case
- Prefer clear APIs, compatibility layers, and migration paths over rewrites for their own sake
- Treat performance, accessibility, maintainability, and developer experience as product features
- Design systems that teams can understand, extend, operate, and trust in production
- Contribute to open source when the solution should outlive a single company or team
Featured open source
NornicDB
Independent graph + vector + temporal MVCC database for AI agents, Graph-RAG, long-horizon memory, and canonical truth systems.
Highlights:
- Neo4j-compatible Bolt/Cypher and Qdrant-compatible gRPC API surfaces
- Unified execution path for graph traversal, HNSW vector retrieval, MVCC reads, embeddings, local LLM reranking/inference, GPU acceleration, MCP tooling, schema constraints, and policy-driven retention
- Agentic memory architecture with decay profiles, promotion policies, canonical graph-ledger supersession, GDPR retention, and MVCC-aware scoring semantics
- Local Apple M3 Max benchmark: vector_only p50 578us at 15,767 req/s; vector_one_hop p50 1.6ms at 6,081 req/s with 800 concurrent requests and 0 errors
uiGrid
Original author of AngularJS UI Grid and maintainer of the modern cross-platform remaster.
Highlights:
- Original AngularJS UI Grid reached 5.4K+ stars and 2.4K+ forks
- Modern remaster keeps the familiar gridOptions / columnDefs / onRegisterApi API surface
- Rebuilt for Angular 21+, React 18+, Web Components, Rust/egui, and native C/LVGL
- Includes virtualization, sorting, filtering, grouping, tree data, editing, keyboard navigation, selection, pinning, state persistence, and CSV/Excel/PDF export
Professional focus
Currently, I am a Staff Software Engineer in AI Labs at CVS Health, working on AI-powered tooling, platform modernization, standards-based application architecture, and enterprise-scale Angular/Web Components migration.
Previously, I have worked as a Principal Software Engineer, Lead Software Engineer, Principal Software Architect, founder, consultant, and open source platform lead across financial services, healthcare, SaaS, automotive, fraud systems, cloud platforms, and UAV hardware/software systems.
Some systems I have built or led include:
- High-security SaaS services for asset-management and global-authentication workflows
- Global Web Component UI frameworks adopted across internal enterprise services
- DITA-based multi-tenant authoring and publishing platforms
- Telemetry and CI/CD integrations for Kubernetes and cloud delivery pipelines
- Experience APIs and insurance workflow UIs
- Consumer UAV flight-controller products sold in 12+ countries
- Build-Your-Own vehicle configurator platforms across major automotive brands

MFixedPoint ⑂
32-bit and 64-bit fixed-point library for fast arithmetic operations. Suitable for performing computationally intensive operations on a computing platform that does not have a floating-point unit (like most smaller embedded systems, such as Cortex-M3, CortexM0, ATmega, PSoC 5, PSoC 5 LP, PSoC 4, Arduino platforms e.t.c). Common applications include BLDC motor control and image processing. Best performance on a 32-bit or higher architecture (although 8-bit architectures should still be fine).
