​In 2014, Sacha achieved a Second Upper LLB (Hons) from the University of Hertfordshire and went on to obtain the Certificate in Legal Practice. Whilst doing so, she completed internships at Dennis Nik & Wong, Raja Darryl & Loh and Adnan Sundra & Low, besides working as a paralegal in Raja Darryl & Loh. Engaging actively in mooting throughout her university tenure, Sacha won all the competitions she signed up for in her final year, eventually being titled the "best mooter". She then completed her pupillage at Azim Tunku Farik & Wong in 2018 and was called to the Bar in January 2019 as an advocate and solicitor.

Sacha commenced practice in general litigation, employment law and industrial relations at a boutique firm in KL before joining Dharmen Sivalingam & Partners in 2020, practicing in these areas as well as others. In doing so, she has been actively involved in representing companies of all sizes as well as individuals at the Industrial Court and various civil courts throughout Malaysia.

In addition, Sacha is passionate about many social causes and has volunteered at organisations assisting in disaster relief, feeding the homeless and campaigning for the ratification of UN's ICERD. It is the latter that inspired Sacha to write her master's degree thesis on racial discrimination in Malaysia; consequently, she obtained an LLM in Legal Practice from Nottingham Trent University in 2019. Sacha is also a member of the Bar Council's Committee on Orang Asli Rights and has participated in sessions dispensing legal advice to the indigenous people of Peninsular Malaysia.
