# Summary Lead Engineer with 6+ years building high-availability, distributed backend systems at scale — from blockchain-based financial settlement platforms to Go-based contact and search services handling **100M+ records**. Currently on the Contacts Platform team at GoHighLevel, improving system design and architecture at scale. > **status:** open to **Staff / Principal Engineer** opportunities.
commit gohighlevel--lead-engineer
Lead Engineer — GoHighLevel
- Driving system design and architecture improvements for the Contacts Platform, supporting high-throughput services relied on across GoHighLevel's multi-tenant SaaS customer base.
- Partnering cross-functionally with product and platform teams to modernize core contact data services for reliability, scalability, and long-term maintainability.
- Bringing distributed-systems and high-scale architecture expertise from prior roles to guide technical direction, design reviews, and engineering standards on the team.
- Mentoring engineers on the team, raising the bar on system-design rigor and production-readiness practices.
commit brevo--senior-to-lead-engineer
Senior Software Engineer → Lead Engineer — Brevo
- Architected and executed the core migration of mission-critical, high-availability contact management microservices from Node.js to Go, scaling performance to sustain 1,000+ RPS / 40k+ ops/min and supporting over 100M+ contacts.
- Drove a 50% systemic reduction in text-based query latencies by redesigning data segmentation pipelines across heterogeneous datastores (PostgreSQL, ClickHouse, Redis), directly improving enterprise-level customer retention.
- Established engineering excellence standards and SLAs for cross-functional product teams; introduced rigorous system-design review processes that slashed post-release production anomalies by over 30%.
- Led and mentored a high-performing squad of engineers, defining technical direction, establishing robust CI/CD and monitoring guardrails, and accelerating sprint velocity by removing technical debt bottlenecks.
- Promoted to Lead Engineer in Jan 2026, recognizing technical leadership and system-design impact.
commit dlt-labs--software-to-lead-engineer
Software Engineer → Senior Software Engineer → Lead Engineer — DLT Labs
- Served as Core Architect for an enterprise blockchain-based supply chain and financial settlement platform, scaling transaction processing from 2k ops/min to 40k ops/min through advanced Node.js runtime and garbage collection tuning.
- Designed a high-performance data replication engine that synthesized multi-source distributed data streams in real-time, drastically reducing cross-system sync lag and unlocking advanced dynamic CRM segmentation.
- Spearheaded production engineering strategy for mission-critical distributed systems, building automated self-healing workflows and debugging frameworks that preserved 99.99% availability SLAs.
- Recognized across 3 elite corporate categories ('Top Achiever', 'Best Improvement', 'Most Efficient Developer') for pioneering technical initiatives that slashed operational infrastructure overhead.
