Lead Architect for Backend Infrastructure and AI/ML

Lucas Arruda is a Staff Engineer / Lead Architect with 15+ years of experience specializing in high-stakes infrastructure, system overhauls, and early product velocity. He partners with tech leaders and founders as an embedded, hands-on technical consultant (15–30h/week) to bridge the gap between initial demos and enterprise-ready systems. He specializes in: Applied AI & Automation (integrating AI engines for practical backend workloads, image classification pipelines, automated log processing, embedding security scanners into CI/CD workflows); HealthTech & Diagnostics (architecting platforms integrating complex clinical diagnostic engines, lab systems, and data pipelines with compliance, telemetry, and authorization); Scale & Telemetry (re-engineering legacy backends, database schemas, and standalone telemetry engines for heavy data flows and millions of users); High-Velocity E-Commerce (building complex payment gateways, transactional networks, and checkout pipelines); Technical Leadership & Mentoring (leading, unblocking, and upskilling engineering teams, accelerating prototyping, and establishing sound architectural blueprints). He is looking for direct engagements with founders, VPs of Engineering, or CTOs needing an autonomous technical leader to own core infrastructure paths without executive overhead. Direct client engagements only; no third-party placement agencies.
