Director of Engineering with 8+ 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 8+ 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 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 8+ years of production engineering.
10+ awards across two organizations — consistent recognition for leadership and technical performance.
Tangible outcomes reflecting engineering leadership done right.
Built and delivered 35+ applications to production across diverse enterprise domains.
Individually engineered 8+ production-grade applications from architecture to deployment.
Orchestrated a seamless monolith-to-microservices migration with zero unplanned downtime.
Integrated multiple AMS platforms and third-party software ecosystems for insurance workflows.
Boosted application performance and speed by 60% through targeted optimization strategies.
Executed large-scale database restructuring in production — zero downtime, full data integrity.
Scaled the engineering team from 2 to 13+ engineers, building a culture of ownership and growth.
Reduced cloud infrastructure costs by 25% through strategic optimization and architecture improvements.
Managed 40+ team members for high-stakes onsite projects with global enterprise clients across industries.
Maintained 100% success rate with top enterprise clients — zero escalations, zero missed SLAs.
Contributed to a specialized aviation MRO and fleet management platform used by global airline operators worldwide.
Led critical disaster recovery operations — restoring system integrity under high-pressure scenarios.
Real-world engineering problems solved across virtually every application domain — from fintech and supply chain to government platforms, transport, messaging, e-commerce, and beyond. A curated selection is shown here; the full picture spans 35+ production applications.

Mission-critical aviation software for fleet and maintenance, repair & overhaul (MRO) management — covering maintenance schedules, compliance tracking, technical records, and airworthiness reporting for airline operators worldwide.
A hyperlocal peer-to-peer marketplace platform for buying and selling across real estate, vehicles, electronics, and services — designed from the ground up for the Indian market. Available on web and mobile with social discovery at its core.
Comprehensive school management platform covering admissions, timetables, attendance, fee management, exam tracking, and parent communication — a unified system for modern educational institutions replacing scattered legacy tools.
Zero-code automation layer on top of enterprise HCM software — enabling organisations to automate HR workflows, bulk data operations, and compliance reporting without writing code. Zapier-style workflow automation, purpose-built for enterprise HR at scale.
Social sports platform enabling athletes to connect, compete, track performance, and support charitable causes through sporting activity — backed by a real-time event-driven backend and community engagement engine.
Government-grade multi-application suite deployed for a national government — a unified ecosystem covering e-commerce storefront, inventory & storage management, point-of-sale (POS), and custom payment integrations. Built for national-scale operations with government-grade security and compliance.
35+ production applications span virtually every category of software. What you see above is a curated sample — the full body of work covers a much wider map.
Three times the company was on the edge. Three times engineering discipline, rapid diagnosis, and decisive leadership brought it back — faster than anyone expected.
A developer's logic error silently propagated bad writes across production data, corrupting records that enterprise clients depended on for live operations. The window to act without permanent data loss was narrow.
Every system went dark. A cascading failure combining routing misconfiguration and database connection pool exhaustion brought the entire platform to a halt — with enterprise clients active on the platform in real time.
An unexpected AWS-side failure, compounded by an architectural gap in integration failover, took down core production services. Enterprise client SLAs were directly at risk — with no guaranteed resolution timeline from AWS.
A broad ecosystem of AMS platforms, communication tools, payment rails, and productivity apps wired together to power enterprise insurance and business workflows.
