Director of Engineering with 7+ years crafting resilient, high-performance systems. I bridge technical depth with strategic vision — turning ambitious ideas into production-grade realities.
I'm Jayabal Rajendran, a Director of Engineering based in Bangalore who believes great engineering is as much about people as it is about code. Over 7+ years, I've evolved from writing my first production lines to architecting systems that serve enterprise clients at scale.
My philosophy is simple: build with intent, lead with empathy, and ship with confidence. I've grown engineering teams from 2 to 13+, orchestrated monolith-to-microservices migrations without a second of unplanned downtime, and earned onsite engagements with global names like Microsoft and Lumachain.
Designed HLD/LLD systems handling real-time data, event-driven microservices, and cloud-native infrastructure on AWS & Azure.
From product ideation and technical scoping to CI/CD pipelines and post-launch monitoring — I own the full development lifecycle.
Built high-performing teams, established Scrum practices, and cultivated an engineering culture focused on ownership and growth.
Reduced cloud billing by 25% and improved application performance by 60% through strategic refactoring and infrastructure tuning.
A progressive trajectory from hands-on developer to driving engineering strategy at an organizational level.
A broad and deep technology stack honed over 7+ years of production engineering, from backend services to cloud infrastructure.
10+ awards across two organizations — a consistent track record of leadership, technical performance, and team impact.
Tangible outcomes that reflect engineering leadership done right — from code quality to organizational impact.
Built and delivered 35+ applications to production, spanning diverse domains and enterprise-grade requirements.
Individually engineered 8+ production-grade applications from scratch — full ownership from architecture to deployment.
Orchestrated a seamless monolith-to-microservices migration with zero unplanned downtime for the core platform.
Integrated multiple AMS platforms and third-party software ecosystems, streamlining complex insurance workflows.
Boosted application performance and system speed by 60% through targeted optimization and caching strategies.
Executed large-scale database restructuring across production environments — zero downtime, full data integrity preserved.
Scaled the engineering team from 2 to 13+ engineers, creating a culture of ownership, growth, and technical pride.
Reduced overall cloud infrastructure costs by 25% through strategic resource optimization and architectural improvements.
Managed 40+ team members across onsite client projects, earning trust from global organizations like Microsoft and Lumachain.
Maintained a 100% success rate with top enterprise clients — no escalations, no missed SLAs, no failed deliveries.
Contributed to OASES, a specialized aviation MRO and fleet management platform used by global airline operators.
Led critical disaster recovery operations — restoring system integrity under high-pressure scenarios with minimal data loss.
A showcase of real-world engineering problems solved with architecture, creativity, and precision.
Words from those who've worked alongside me — the engineers I've led, the clients I've served.
Whether it's a leadership opportunity, a technical collaboration, or just a conversation — my inbox is always open.
