Jay Jayasai Gouthaman

Hands-on Software Engineering Leader Mobile · Frontend · Backend Services · Cloud · Auckland

My CV tells you what I've done. This site tells you who I am.

I'm a hands-on software engineering leader with 12+ years of building mobile, frontend, backend services and cloud software, and growing the people who build it with me. Away from the keyboard, you'll find me on stage at Toastmasters, debating ideas at my book club, or playing futsal with friends. I've recently made Auckland home, and I'd love to bring the same curiosity and warmth to my next team.

Built for personal use and published on Google Play; it has since been retired as I'm no longer maintaining it.

About me

The person behind the CV

I'm Jayasai, Jay to most people: a Sri Lankan-born, hands-on software engineering leader now living in Auckland. I love turning messy problems into calm, working software, mentoring the next generation of engineers, and finding my voice at Toastmasters.

In the next few years
Build software that helps people take their next step, and grow the engineers who build it with me, bringing my mobile, frontend, backend and cloud experience to an Auckland team as a hands-on software engineering leader.
5+ years
Grow into engineering leadership, building the kind of teams people remember working in.

Toastmasters journey

From nervous first speech to first place

My very first speech won Best Speaker. It was the moment I realised public speaking was a skill I could build, not a talent I lacked. Eight years on, I'm still building it.

Beyond work

Away from the keyboard

Books, karate, futsal, good coffee and a very fluffy supporter. The things that keep me curious.

  • An evening session at Pick a Book

    Books

    Pick a Book

    A member of Pick a Book, a community book club in Sri Lanka where we read, present and debate ideas together. Sharing a book with a room of curious readers keeps me learning outside tech.

  • 26th International Budo-Camp · Sri Lanka, 2017

    Martial arts

    Budo-Camp 2017

    Karate taught me discipline, focus and respect long before I led teams. In 2017 I was part of the 26th International Budo-Camp in Sri Lanka, training alongside martial artists and masters from around the world.

  • Staying active

    Futsal and karate

    Futsal with the Creative Software team, and karate. I've also volunteered at youth and martial arts exhibitions.

  • Soaking up ideas at TEDx

    Ideas

    TEDx

    I love listening to leaders. A great TEDx talk sends me home with one idea I can't stop thinking about.

  • Coffee

    Coffee, taken seriously

    My love for coffee went far enough that I completed a barista coffee-making course. Fair warning: if your office has a coffee machine, consider me your unofficial barista.

    • Road trips

Team & culture

Strong teams are built off the screen as much as on it. Two days at Avani, Kalutara with fellow Team Leads and the Ops team: endurance challenges, paintball and problem-solving under pressure.

Curious beyond code

How real products are made

In 2026 I completed four Industrial Development Board of Ceylon workshops on export procedures, food and beverage processing, and print production. Understanding how real products are made and shipped helps me build software that fits real businesses.

  2. King Coconut Water Bottling Technology for the Export Market
  3. Value-added Tea Manufacturing
  4. Food Export Procedure
