Selected Engineering Projects
Independent Engineering Projects
AI Systems Engineer | ReveLith Office Suite
Independent Engineering Projects
2026 to Present
- Developed a pre-release desktop office suite spanning Docs, Sheets, Slides, PDF, Markdown, and Shell workflows.
- Connected Electron orchestration to native Rust sidecars, WASM text shaping, provider-neutral AI context, and format-specific document engines.
- Designed format-specific editing paths for DOCX, XLSX, PPTX, and PDF with targeted patching, fidelity fixtures, and reviewable save behavior.
- Implemented local-first security boundaries, validated IPC contracts, automated test gates, and desktop packaging paths for Windows, macOS, and Linux.
Systems Engineer | Aurelinx HR Intelligence Platform
Independent Engineering Projects
2026 to Present
- Developed a full-stack HR intelligence platform connecting workforce analytics, candidate workflows, AI-assisted analysis, and operational follow-through.
- Connected Next.js views to FastAPI routes for authentication, employees, candidates, analysis, intelligence, integrations, and enterprise operations.
- Implemented guarded chat tools with role checks, approval-gated deletion, secret redaction, workflow events, and audit records.
- Documented PostgreSQL, Redis workers, Qdrant, Alembic migrations, Docker Compose services, and a Tauri 2 desktop shell; the repository contains seven backend pytest files and two client test files.
Backend Engineer | AverQel Workspace
Independent Engineering Projects
2025 to Present
- Built the backend path from document upload and malware scanning through object storage, extraction, OCR, chunking, embeddings, and indexing.
- Designed multi-tenant research workflows around citation-backed retrieval, connected tools, governed automation, and explicit ownership boundaries.
- Implemented FastAPI services, PostgreSQL and Redis-backed runtime services, connector policies, encrypted credentials, and observable recovery paths.
- Kept evidence, permissions, and runtime state outside the model so answers and actions remain inspectable from source to outcome.
- Recent local validation recorded 806 backend cases and 280 frontend tests passing against the checked-out v1.2.12 source tree; this is not a production adoption or uptime claim.
AI Systems Engineer | Alcyoneus OS
Independent Engineering Projects
2025 to Present
- Developed an agent runtime around state graphs, provider adapters, typed tools, memory, streaming, and resumable execution.
- Separated model suggestions from executable authority through guardrails, policy decisions, identity, scoped secrets, and tenant-aware access control.
- Added A2A, ACP, and MCP integration surfaces, sandboxed execution, approval-aware workflows, structured events, and operational telemetry.
- Established evaluation and hardening paths so agent behavior can be tested, observed, and recovered in documented workflows.
- A local full-suite run of the checked-out main branch recorded 3,159 passed, 13 skipped, and 31 warnings from 3,172 collected tests.
AI Systems Engineer | NOESIS-Σ Inference Engine
Independent Engineering Projects
2025 to Present
- Designed an Alpha Experimental inference research system where a numerical Operator-Split Core governs state and evidence-related processing before generation.
- Developed an Alpha Experimental research codebase around operator-split state dynamics, ICNN energy components, verifier services, and experimental runtime modules.
- Implemented conservative, dissipative, and projection paths with configurable numerical limits and targeted tests; no formal stability, convexity, or performance guarantee is claimed.
- Implemented optional AES-GCM snapshot encryption, Ed25519 signing, restricted DSL evaluation, and receipt checks within the repository's research-grade security boundary.
- Maintained 106 test files and 501 test-prefixed functions as a static source inventory; execution results, benchmark accuracy, and production readiness are not claimed.
Systems Architect | FAIM-Native Memory Engine
Independent Engineering Projects
2024 to Present
- Designed a deterministic AI memory graph with fractal inheritance, antisymmetric contradiction detection, and a 10-signal retrieval path with zero ML models in scoring.
- Built the Fractal Inheritance Graph so parent fractions, residual novelty, contradiction handling, and graph traversal remain mathematically inspectable.
- Implemented the retrieval engine, authentication and API-key lifecycle, self-evolution runtime, FIG View, and deployment hardening through end-to-end delivery.
- The current checkout passed 1,009 pytest cases, skipped 1, and emitted 500 warnings in a local run. The repository also documents FastAPI, PostgreSQL, Redis, Qdrant, Next.js, TypeScript, Docker, and a deterministic 256-dimensional native vector path.
