Introduction

I am a motivated researcher in the field of pharmaceutics and pharmaceutical technology. My recent work focuses on developing modified liposomal and polymers as a drug delivery system for biomedicines. For further research, I believe that the research in stabilizing and localizing the secretome (stem cell-free) would be advantageous for regenerative therapy. In another field, coding or IT thing is my favorite job. I am interested in studying the impact of the diversity of genetic information and individual preferences on various drug effects. The study would be the key to develop specific protein targeting and more precise therapy. Health sciences knowledge and programming skill are a potent combination to develop advanced sciences. 

Education 

• Dissertation: Stem cell’s secretome delivery systems. 

Work Experience

As a researcher: Designed research procedures and timeline; designed and produced liposomes with excellent shape and stability, with high entrapment efficiency (99,91%); designed and produced a film-forming spray that improves biomolecules' in vivo stability, bioavailability, and effectivity. 

• Chief technology officer (CTO): managed the following several software developments: 
• Developed Hellomora software for medical document management.  The system allows users to store and share their medical data among health workers across institutions to simplify diagnosis, referral, verification, etc. For further advancement, artificial intelligence will be applied to extract and process any form of medical data into a predicted health profile. (https://hellomora.com).
• Developed DockFlin software for simple and multiple ligand/protein docking. A novel algorithm was applied for scoring the activity of amino acid residue on protein binding pockets using dynamic ligand-protein interactions.
• Developed EXC-Sol software to simplify the pre-formulation process. EXC-Sol can analyze multivariable data to predict the compatibility among the excipient chosen. There are a lot of alternative excipients and their ranged concentration to help you design various possible formulas. 

• Developed InaTTI software for mobile laboratory systems.  The Ministry of Health of Indonesia uses the system for Covid-19 test, trace, and isolation management (https://inatti.id). 

Industry

• As a Quality Assurance: analyzed batch record, carried out transport validation, packaging validation, filled out data for drug registration.
• As Quality Control Assistant: in process control (IPC) of tablet compressing process, determined tablet dimensional, heavy metal contamination, packaging, friability, hardness, etc.
