I engineer high-performance, backend systems with a focus on data integrity, geospatial telemetry, and mission-critical reliability. My work bridges the gap between high-level business logic and low-level systems performance.
Status: Open Source / Proof-of-Concept Repository: github.com/3steve3/HIRTP-Link
HIRTP-Link (High-Integrity Resumable Transfer Protocol) is an application-layer protocol designed for mission-critical data exchange in hostile or unreliable network environments (SatCom, IoT Edge).
- Dual-Layer Integrity: Implements CRC32C transport-layer checksums for packet validation and SHA256 application-layer identity for final end-to-end verification.
- Stateless Resumption: Engineered a recovery-oriented state machine that uses identity caching to resume interrupted multi-gigabyte transfers in milliseconds without redundant re-hashing.
- Cross-Platform Engineering: Developed a resource-efficient Rust client for edge devices and a high-velocity C# (.NET 10) base station compiled with Native AOT for sub-millisecond startup and minimal memory footprint.
- Chaos-Ready: Validated protocol resilience via integrated "Chaos Monkey" simulation to ensure zero data loss during intentional stream severing.
Status: Proprietary / Commercial OS for Field Services & Logistics

Bedrock is a high-integrity, composable commerce operating system designed to track "True Profit" by treating operational friction as first-class data. The architecture is a horizontally scalable modular monolith engineered for forensic data accuracy and auditability.
Hybridized Vertical Slice Architecture (VSA):
A modular monolith design that groups related commands and queries into cohesive feature slices, preventing the complexity of premature microservices while maintaining strict logical boundaries.
Segregated Transport Layer (CQRS-Lite):
- Commands (Writes): All state changes are enforced via gRPC for strict contract adherence, high-performance serialization, and transactional rigor.
- Queries (Reads): Data retrieval is exposed via GraphQL, allowing clients to fetch complex, nested projections in a single round-trip without over-fetching.
Forensic Audit Trail:
Leveraging TimescaleDB hypertables to create an immutable, append-only ledger of every system event. We don't just track current state; we track the delta of every business decision.
Database-Level Multitenancy:
Deeply integrated PostgreSQL Row Level Security (RLS) ensures strict tenant isolation at the data layer, preventing application-level leakage.
- Languages: C# (.NET 10), Rust (learning), SQL (Postgres/Timescale), Python
