About
Product engineer for technical workflows, with a bias toward adoption, tooling, and operational clarity.
Across MetaLearner, GovTech, the Singapore Armed Forces, and client delivery work, Chai keeps returning to the same kind of problem: technical systems that are hard to adopt, too manual to operate, or too brittle to trust. That has translated into onboarding flows, internal tooling, automated testing, SEO improvements, and operational training systems, with a consistent focus on making complex workflows clearer, more reliable, and easier to use.
Experience timeline
Four roles across product, platform, client delivery, and cyber operations.
Each role sharpened a different part of the same practice: client delivery, platform enablement, operational leadership, and product adoption.

Software Engineer Intern
The work sat at the intersection of product onboarding and workflow usability: reducing dependence on support while making exploratory analysis easier inside the product.

Combined multi-step onboarding, feature entry points, prompt-writing support, and structured guide categories into a clearer self-serve experience.
Overhauled chart usability with legends, tooltips, responsive hover states, and an interactive time-series chart with zoom, pan, hover inspection, and dynamic scaling.
Prototyped a real-time messaging architecture with FastAPI, WebSockets, Redis pub/sub, PostgreSQL, JWT, and Docker Compose to evaluate a scalable, low-latency chat system.

Revamped the Developer Portal community section to improve SEO and indexing, doubling traffic from 2.5k to 6k weekly users.
Integrated Cypress into an existing Amplify and GitLab CI/CD pipeline, reducing manual visual checks and cutting deployment time by 20 minutes per merge to production.

Impact work
Resumify applied the same product instinct to inclusive hiring.
Outside internships and formal roles, this is the clearest example of building with both product judgment and social purpose: simplifying resume creation, job matching, and employment access for people who are often excluded from standard hiring flows.

Built the user-facing platform in Next.js to make resume creation and job matching more accessible for underserved communities, including ex-offenders and persons with disabilities.
Partnered with the Singapore Prison Service and Yellow Ribbon Project on a pilot that supported rehabilitation and reintegration through a one-stop centre and online consultations.
Extended volunteering-inspired work into a real employment-access initiative, including a 2025 MOU signing with Yellow Ribbon.
