Minimarket Rosalina | Jan 2016 - Present

Co-Owner

Our family retail business, established in 1993, is located in Ngoro, Mojokerto, and includes a minimarket, clothing store, and food stand. Since becoming co-owner alongside my mother - who is also my mentor, I've taken on various roles to drive growth: • Trained a retail sales manager to oversee daily operations. • Improved cash flow by reducing slow-moving product stock using data from our store information system. • Reduced the debt-to-capital ratio by increasing cash flow and managing profits, boosting overall sales. • Launched online stores on major Indonesian marketplaces, Tokopedia and Shopee. • Opened our Surabaya branch, which generates our highest online revenue. • Created a social media specialist team for Instagram and Facebook, achieving a 1.94% engagement rate on Instagram. • Launched a Google Ads campaign, reaching a 3.72% interaction rate all time. These initiatives have significantly impacted the growth and success of our family business.

Erosa | Dec 2015 - Apr 2018

Small Business Owner

As the solo owner of a small personalized gift business, I wore many hats. • As the designer, I made more 1000+ design for mugs which was my main product, but also for cards, pouches, packaging, canvas, etc. • For marketing, I took the product photos using Sony A6000 camera and edited them using Adobe Lightroom. I mainly post them on Instagram and used ads every once in a while to drive new customers in. At its peak, I successfully reached 1% engagement rate. • For sales, as it was only online based store, I put my store on online marketplace such as Tokopedia and Shopee. Technologies / Tools: Adobe Illustrator, Adobe Photoshop, Adobe Lightroom, Spreadsheets, Instagram, Tokopedia and Shopee
