Profile
Ikhsanuddin Syamsuri
Ikhsan is a senior software engineer with 10 years of building web products. He works from Jakarta (UTC+7) and has worked fully remote with teams in Singapore and the US since 2023.
At Boon he builds AI-assisted features for construction preconstruction, end to end in React and Ruby on Rails: document analysis, bid generation, guided onboarding for new Boon Agent users, and the trial funnel. He led Takeoff V2, the move of the blueprint canvas from a React component graph to a PixiJS/WebGL renderer with a spatial index and tiled rendering.
His background in psychology shapes how he builds software: he cares about how people actually use what he ships, and he is comfortable with data research and statistical analysis.
In 2012, he started in graphic design to help with tuition fees in psychology. That detour became a career: digital marketing, analytics, and SEO. Since 2016, software engineering full-time.
- Frontend. React and TypeScript daily, PixiJS/WebGL for the blueprint canvas at Boon. He has also shipped with Next.js, Vue/Nuxt, Svelte, and React Native (ULO, 10,000+ downloads).
- Backend. Ruby on Rails at Boon. Node.js and Go in production before that, including 5 backend services in TypeScript and Go for a decentralized exchange: GraphQL and REST APIs backed by PostgreSQL, MongoDB, and Redis. Earlier in his career: Nest.js, Laravel, and Java.
- Devops. Docker and Kubernetes since 2021, infrastructure as code with Terraform and Ansible, CI/CD on GitHub Actions, and AWS in production.
Remote-first, across timezones.
Since 2023 he has worked fully remote with teams in Singapore and the US: async-first communication, clear written updates, and ownership of features from system design to deploy and monitoring.
