I'm a Senior Engineering Manager who stays close to the code. I've scaled engineering orgs across SEA and South Asia — leading platforms that serve 97M+ users across 10+ countries — and built security practices that actually hold up under regulatory scrutiny.

My belief: a manager who can't read the architecture document can't lead the team that wrote it. Currently pursuing an MBA and working towards CISSP — because the problems I care about sit at the intersection of business, engineering, and security. Outside work, I tinker: home labs, IoT, smart home automation, and anything that can be hacked together on a Raspberry Pi.

I fully embrace AI — I've spent years testing, building with, and watching its capabilities compound in real time. There's always one or more active AI-driven side projects running. Beyond development, I reach for AI across planning, writing, research, and day-to-day decisions. The right model for the right job.

I've built and led engineering teams across five markets in SEA and South Asia — hiring locally, navigating each country's talent landscape, and managing across time zones, languages, and work cultures.

01ORG

Team Building & Org Design

Hiring, structuring, and growing distributed engineering teams of 20–30+ across SEA and South Asia. Building the rituals and culture that make teams retain and perform — not just recruit.

Reduced hiring cycles · improved retention · expansion into new markets

02TECH

Hands-on Technical Leadership

Staying close to the codebase, architecture decisions, and PR reviews. Technical credibility that earns trust from engineers — and translates complex tradeoffs into plain language for stakeholders.

Faster delivery cycles · reduced operational risk · improved engineering predictability

03SEC

Security & DevSecOps

Embedding InfoSec into the SDLC — not as compliance theatre, but as an engineering discipline. Threat modelling, secure pipelines, incident response, and teams that take ownership of security outcomes.

Reduced vulnerability exposure · security culture that scales with the team

04EXEC

Delivery & Engineering Strategy

Turning product goals into roadmaps that engineering can actually execute. Managing scope, stakeholders, and cross-timezone complexity — so the business gets reliable delivery without micromanaging the team.

On-time delivery · improved cross-functional alignment · predictable velocity

05AI

AI-Augmented Delivery

Management, planning, product grooming, solutioning, UI/UX design, development, and deployment — paired with AI — compresses what used to take months into weeks. It gives teams disproportionate leverage, and makes it possible to take a product from concept to live end-to-end. Each AI model has its strengths; knowing which to reach for is the skill.

concept → production in weeks · amplify delivery across the entire org · ship faster with or without a team
