Hello, World!
I am Paro.

I build the systems behind how money moves.Mostly Java. Increasingly AI. Always engineered with intent.

I’m a software engineer based in Singapore, working on payment and settlement systems.

My background spans business analysis and backend engineering, which means I care about the “why” just as much as the architecture.

Clean systems, sensible decisions and no unnecessary complexity.

JavaSpring Boot, REST APIs and backend services.
Backend EngineeringMicroservices, APIs and system design.
Distributed SystemsKafka, AMQ and event-driven architecture.
SecuritySecure design, authentication and application security.
AI EngineeringPractical AI-assisted workflows for code, analysis and engineering productivity.

Also around often: MySQL, Docker, Kubernetes, OpenShift, Jenkins and Git.

Software Engineer, Senior Associate
Leading engineering and delivery across payment and settlement platforms, from backend architecture and APIs to cross-service integrations.
Several systems. Several teams. One suspiciously organised set of tabs.
Mar 2026 — Present
Software Engineer, Associate
Built Java and Spring Boot services for cross-border payments, deferred payments and interbank settlement.
APIs, event-driven systems, secure releases — and a lot of money moving without making a scene.
Jul 2024 — Mar 2026
Software Engineer, Graduate Associate
Moved fully into backend engineering and started building the systems I had previously been analysing from the other side.
Same questions. More Java.
Nov 2023 — Jul 2024
Business Analyst, Graduate Associate
Worked between business requirements and technology, translating payment problems into things engineering teams could actually build.
This is where the habit of asking “why?” started. It has not stopped.
Jul 2022 — Nov 2023

Software Development Intern · Avetics Global
Built software in a startup environment where the requirements moved quickly and so did everyone else.
Jan 2021 — Jul 2021
Data Science Intern · Sembcorp Industries
Worked with data before deciding I preferred building the systems producing it.
Jun 2019 — Aug 2019

From business analysis to backend engineering — same habit of asking why, just with more Java.

Always happy to talk about backend engineering, payments, AI workflows or interesting technical problems.
