• Application Segment & 99.9% Uptime: Engineered and administered the Akwa Ibom State (AKS) application infrastructure segment hosted at Equinix Colocation on the datacenter team's provisioned VMware ESXi cluster, ensuring 99.9% uptime for digital tax collection and the state portal (akirs.ak.gov.ng).
• Modernization & Cluster Migration: Spearheaded the migration of 4 core production application servers to hardened Linux within the allocated DMZ, configuring static Netplan network interfaces for strict static IP binding, eliminating licensing overhead, and ensuring zero service disruption during cutover.
• Perimeter Edge Routing & DDoS Defense: Configured edge reverse proxy routing (Traefik) for incoming traffic routed through the Windows bastion and Sophos firewall; deployed multi-homed dual-IP networking on edge Linux instances to isolate inbound from outbound traffic and prevent DDoS compromise.
• Automated Deployment & Access Controls: Orchestrated containerized microservices and automated deployment workflows using self-hosted Coolify via internal static IPs and encrypted SSH keypairs with least-privilege RBAC.
• Business Continuity & Disaster Recovery: Configured application backup schedules and executed non-destructive instant full-VM restore drills utilizing provisioned Synology NAS (RAID 5 + NVMe cache) and Veeam Backup Appliance over the dedicated storage fabric.
• Financial Data Reconciliation: Built automated revenue reconciliation platforms (FastAPI, PostgreSQL, Redis, ChromaDB) standardizing taxpayer and banking records across 31 Local Government Areas, eliminating manual verification backlogs.

Core Skills: VMware ESXi 8.x, vCenter, Linux DMZ, Traefik, Coolify, Sophos XGS 138, Cisco Catalyst 1300, Windows Server 2025 AD DS, Synology DSM, Veeam Backup, Docker, Python, FastAPI

• Developer Productivity & CI Velocity: Restructured core engine architecture for CCXT (industry-standard crypto trading framework with 34,000+ GitHub stars, merged PR #30723), eliminating monolithic recompilations and significantly accelerating daily developer check and test cycles across ~200 exchange venues.
• CI Pipeline Stability & Resource Savings: Eliminated catastrophic runner Out-of-Memory (OOM) crashes and build timeouts on high-core continuous integration machines by optimizing transpiler child-process fan-out, worker thread heaps, and AST batch caching.
• High-Performance Build Tooling: Integrated automated high-performance linker detection (mold / lld) into cargo runner workflows to cut compile and link times, maintaining 100% backward compatibility for downstream production users.

Core Skills: Rust, TypeScript, AST Transpilers, Node.js Worker Pools, mold / lld Linkers, Concurrency, Cargo

• AI Agent Security & Sandboxing: Engineered secure, sandboxed integrations for NEAR AI's agentic operating system (IronClaw, PR #34), enabling autonomous agents to safely connect with third-party platforms (GitHub, Discord) without compromising host system integrity.
• Zero-Trust Access Control: Implemented strict capability-based security boundaries, preventing unauthorized data exfiltration, memory leakage, and unauthorized external network access by third-party plugins.
• Defensive Engineering: Built rigorous input sanitization, path traversal defenses, and safe byte-boundary serialization to protect against arbitrary execution vulnerabilities.

Core Skills: Rust, WebAssembly (WASM), wit-bindgen, Capability-Based Security, System Sandboxing

• Low-Latency Trading Architecture: Led development of high-throughput trade execution pipelines in Rust and Python, streaming real-time order books with sub-millisecond execution speeds for algorithmic digital asset trading.
• Concurrent Market Data Ingestion: Constructed scalable WebSocket streaming microservices (Tokio) capable of handling volatile market surges without memory leaks or dropped order messages.

Core Skills: Rust, Python, Tokio, WebSockets, Low-Latency Market Data, Concurrency

• Cloud Backend & Automation: Engineered core backend microservices and asynchronous task pipelines (Python, Celery), streamlining daily operational workflows and reducing manual data processing overhead.
• Observability & Downtime Reduction: Reduced incident resolution times and system downtime by architecting real-time application performance monitoring (APM) and centralized telemetry (GlitchTip, Sentry) across production cloud workloads.
• Secure Cloud Operations: Administered production cloud infrastructure (Azure Linux VPS) with automated backup routines, process supervisors, and hardened access controls.

Core Skills: Python, Microsoft Azure (Linux VPS), GlitchTip, Sentry, Telemetry & APM, Systemd, Reverse Proxies, Docker

• Framework Integration & Developer Tools: Contributed native Actix Web support to the SeaORM Pro admin ecosystem across 94 files, introducing secure JWT session authentication and an interactive GraphQL explorer for relational database management.

Core Skills: Rust, Actix Web, SeaORM, GraphQL, JWT, Relational Schema Management
