12+ years building production distributed systems. Custom in-memory databases, write-ahead logging, crash recovery, real-time event delivery, failover systems, cross-region latency diagnosis down to packet capture. The infrastructure that has to be right before anything intelligent runs on top. Go, Rust, Java.
What runs on top: rules engines with deterministic state transitions. Domain models that represent cognitive acts. Configurable type systems with temporal logic and provenance chains. Storage engines where domain logic executes during traversal with ACID guarantees. Neuro-symbolic architecture that governs language models instead of trusting them.
Built and led a 40+ person engineering organisation. Senior escalation ownership as the person accountable to the C-suites and VPs at 10 PM when production is down and revenue is at risk.

Engineering security and reliability assessment capabilities for a platform that continuously improves compound AI systems from production feedback. Building agent-driven evaluation infrastructure, from sandbox orchestration and execution boundaries to structured reporting, across the security, safety, and operational resilience surface.
Designing and prototyping multi-agent system kernel in Rust with PostgreSQL/pgvector: event loop, geometric routing, per-action authority checks with immutable receipt trails, multi-tenant isolation. Research programme on systems infrastructure for edge AI and embodied intelligence. Published at AAAI 2026 and ACM WWW 2025.
Built a Go-based in-process in-memory data platform for a neurosymbolic knowledge graph engine. Write-ahead logging with double-buffer concurrent flush, transactional MRSW ACID engine with session overlay, targeting 100K write QPS without blocking readers. Subsecond failover, 60-second crash recovery. Hardened AI pipeline integrity against adversarial inputs. Diagnosed cross-region tail latency via packet capture.
Built a regulated QR payment platform from zero. Protocol-layer abstraction over payment terminal and banking message formats. Hired and scaled teams across mobile, backend, firmware, and infrastructure. Security architecture meeting PCI-DSS with penetration testing and Bank Indonesia regulatory compliance.
Built and led a 40+ person cross-functional organisation owning the canonical integration layer across all product domains. Designed the enterprise transaction platform: core subledger with double-entry accounting, electronic money, lending products, reconciliation, host-to-host banking integration. 100K+ daily customer transactions bursting to 3M+ read QPS during flash sales. Senior escalation DRI for high-severity production incidents. ISMS/ISO 27001.
Built the transaction, rules, and workflow engine that became the company-wide foundation: state machine with forward-chaining rules for deterministic, auditable execution at scale. Later expanded into the full subledger and enterprise transaction platform.
Enterprise contact centre platform development. Diagnosed production memory leaks and performance bottlenecks. Coordinated support across Sunnyvale, Glasgow, and Jakarta.
