About Me
If you're here as an engineer, a security practitioner, a recruiter, or just someone curious — welcome.
Feel free to explore the garden and take what's useful.
Executive Summary
I'm Rohit Jacob Mathew, a Staff Software Development Engineer building security-first platforms at scale. I work on SecOps and platform engineering at Trellix, turning complex security, compliance, and scale requirements into reliable, observable, cloud-native platforms that teams can confidently build on.
Over the years, I've worked across the full spectrum of platform engineering — from early-stage scale-ups to enterprise security — with a consistent focus on security, privacy, and developer experience.
🏗️ What I Work On Today
As part of the Platform Engineering team at Trellix, I operate at the intersection of architecture, technical leadership, and execution, owning and influencing systems that run at enterprise scale.
Current Focus Areas:
- Co-architecting a data pipeline services handling security telemetry
- Leading observability strategy with early OpenTelemetry adoption
- Designing secure, cloud-native microservices
- Building enterprise-grade services for FedRAMP
Platform Impact:
- Supporting Trellix Marketplace & Developer Portal
- Evolving ePO cloud security platform
- Mentoring engineers on security & architecture
Impact shows up in improved real-time threat detection & improved incident response, without compromising developer velocity.
📈 Scaling Systems in the Real World
Before Trellix, I was part of the core engineering team at Turtlemint, where I helped scale the platform from 20,000 to over 1 million insurance agents — a 50× growth journey.
Engineering Challenges:
- Designing scalable backend systems
- Leading service rewrites for performance
- Migrating systems to Kubernetes
- Performance monitoring & reliability
Leadership Impact:
- Improving developer workflows
- Building better tooling & documentation
- Mentoring engineers during rapid scaling
- Balancing speed with system health
Key Learnings:
- Building for growth under pressure
- Operating in production at scale
- Long-term vs. immediate needs
- Team scaling & knowledge transfer
🔐 Identity, Security & Privacy
Security isn't something I "add on" — it's foundational to how I design systems. As a former Auth0 Ambassador, I contributed through writing, speaking, and sharing best practices around identity and authentication.
🚀 Developer Experience & Knowledge Sharing
I care deeply about developer experience — not just tools and APIs, but how engineers learn, collaborate, and grow. My journey through seven internships, including time at HackerRank, still influences how I approach mentoring and platform design today.
This site is my digital garden — a place where I share lessons from building systems in production, thoughts on security and scale, and ideas that sit somewhere between work and curiosity.

🌟 Beyond Work
Outside of engineering, I'm driven by curiosity and craft. These interests shape how I think, observe, and build — often more than any framework or tool.
Creative & Cultural:
- Discovering new music on Spotify and attending gigs/festivals
- Collecting vinyl records and exploring music history
- Appreciating watches and craftsmanship
- Reading long-form content and deep dives
Active & Social:
- Following multiple sports like football (soccer), F1 and tennis
- Playing sports and staying active
- Exploring restaurants and local food scenes
- Traveling and exploring new places
