I am a hands-on Software Architect and Systems Recovery Lead with over 20 years of experience in the Java ecosystem. I operate through my company, SWARCS, acting as a tactical B2B contractor for businesses facing critical production anomalies, heavy technical debt, or scalability ceilings.
My background is a mix of rigorous engineering and extreme stress tolerance—including an M.Sc. in Software Engineering (GPA 9.64) and 8 years of active military service as an Air Defense systems engineer and commander. I specialize in stepping into degraded production environments where data integrity and system availability carry major operational risks.
What I bring to the table:
- Technical Forensics & Legacy Rescue: Code-level, zero-downtime decoupling of enterprise monoliths and structural diagnosis of complex distributed runtime anomalies.
- High-Concurrency & Performance Tuning: Designing thread-safe write loops, low-latency state synchronization models, and optimizing memory footprints under strict CPU/RAM constraints.
- Regulated & Event-Driven Platforms: Translating multi-jurisdictional compliance rules into deterministic server-side logic, and stabilizing high-throughput messaging meshes (Kafka/RabbitMQ).
Recent production execution examples:
- Re-architected core transaction pathways into deterministic state engines to resolve distributed locking issues and database connection starvation under intensive write loads.
- Designed and built core event-driven microservices for a public safety emergency notification infrastructure, maintaining zero dropped messages during heavy event bursts.
- Refactored graph traversal paths using low-level Java primitive arrays to lock in maximum CPU cache locality for a European renewable energy grid routing system.
I am looking for challenging part-time or full-time consulting/contract (B2B) engagements where you need senior technical authority to unblock your architectural roadmap, handle high-stakes refactoring, or stabilize infrastructure mid-flight.
