He worked as an iOS engineer at Wayfair from 2019 to 2020, attaining the title of iOS Engineer II.

From 2022 to 2024, Chan co-founded timelyAI, a workforce technology venture whose ultimate fate, whether it was acquired, wound down, or otherwise absorbed into later work, isn't documented in available public sources. He subsequently served as a senior software engineer at Vault.fm from 2024 to 2025 before turning his attention to Sira.Template:Better source needed[3]
Chan co-founded Sira in 2025. The company is designed as an AI-native workforce management platform targeted at industries that rely heavily on deskless and field-based employees. It offers an integrated suite of tools that includes automated time tracking, payroll processing, employee scheduling, and human resources functions. The platform uses artificial intelligence to automate routine administrative tasks, such as detecting missed clock-ins and flagging scheduling anomalies. The goal is to reduce manual overhead for managers overseeing distributed workforces. Sira's clients include companies in sectors such as private security, cleaning services, landscaping, and home health care. The article doesn't identify Sira's other co-founder or co-founders by name, and no independent third-party sources have been identified to corroborate details about the company's founding team.Template:Better source needed[4]
Sira operates in a competitive segment of the workforce management software market. Established platforms such as Homebase, Deputy, and When I Work offer overlapping functionality for hourly and field-based workers. Sira's stated differentiation is its AI-native architecture, which it positions as automating tasks that competing products require managers to handle manually.Template:Better source needed[5]
In 2025, Sira announced a $3.4 million seed funding round. The names of participating investors, the precise date of closing, and the stated use of proceeds have not been confirmed by an independent news source as of the time of writing.Template:Better source needed[6]
