Hi, I'm Princewill. I build web platforms that scale.

Tel Aviv, Israel

• Cut cloud-scanner end-to-end scan time by 50% by refactoring the concurrent pipeline to a bounded worker-pool with back-pressured channels; validated with pprof and benchstat.
• Built an entropy-based secrets detection engine in Go that reduced false positives by 40% across cloud artifact scans while preserving recall on 25+ credential formats.
• Played a key role in incident response during a security breach — forensic investigation, root cause analysis, and attack-vector identification.
• Expanded observability with Datadog metrics, traces, and SLO-aligned alerts, cutting mean time to detection on scanner regressions.

Florida, USA (Remote)

• Led a team of 8 engineers building a virtual-lane driver platform; designed a Go microservice architecture on AWS (ECS, MSK, RDS) serving 15k concurrent drivers with p99 dispatch latency < 200ms.
• Shipped real-time call signalling and GPS tracking over WebSockets and Server-Sent Events, sustaining thousands of concurrent long-lived connections per node.
• Implemented geo-fencing in Go using ray-casting, evaluating 5k points/sec per worker with lock-free hot paths.
• Architected CI/CD with Docker and GitHub Actions, cutting manual ops by 50% and accelerating release cadence by 30%.

Lagos, Nigeria

• Architected a cryptocurrency bill-payment platform letting users pay bills directly with crypto — growing users from 0 to 457k.
• Horizontally scaled Django and FastAPI APIs to support 10k daily transactions with high availability.
• Integrated the Go codebase with Ethereum smart contracts for on-chain payment execution, then expanded multi-chain support to Stellar and beyond.
• Automated refunds with Celery workers detecting failed transactions, reducing refund turnaround by 70%.

Remote

• Managed 5 engineers building Algorand and Ripple wallet-management systems; owned Python SDK integration with the XRP Ledger.
• Designed an order-matching service pairing users with best-available swap offers across multiple asset pairs.
• Introduced Docker and CI/CD tooling, cutting deployment time by 50%.

Remote

• Cut query latency by 50% on high-traffic endpoints through index tuning, join rewrites, and query-plan optimisation.
• Built a Django + Elasticsearch indexing engine powering full-text catalog search across a large product inventory.
• Tuned Nginx load balancing to smooth multi-instance traffic during high-volume campaign spikes.
