    Having a thirst for knowledge and passion for data, I was keen to work towards a career change. •► My exciting learning journey was focused on Data Analysis with Python & SQL; as well as Data Visualization with Tableau – critical problem-solving skills, and compatible with my Financial Data Analysis background. •► To that end, I transferred to a part-time role in Hospitality, reduced my working hours, and dedicated more time to my studies. •► Having created a new portfolio (links above) and acquired 25+ MOOC Certificates since May 2020, I am now seeking to secure a relevant position – and add value in a data-driven environment. •► “Data Scientist with Python track”: https://www.linkedin.com/feed/update/urn:li:activity:6719790548946849793/ •► “Exasol Database Certified Associate”: https://www.linkedin.com/feed/update/urn:li:activity:6676061502635552768/ •► “JavaScript“, “Node.js” & “D3.js”: https://www.linkedin.com/feed/update/urn:li:activity:6760178358207700992/ •► Apart from financially supporting my studies, my day role allows me to continue gaining knowledge in an industry relative to my previous (FMCG: Food/Beverages) – as well as apply practical ideas on process improvement, and serve my customers and team with a smile. Key Accomplishments (Day Role) : •► Bookwormed our 10 mandatory e-modules in 2 months and 1 week, which was congratulated via email by HR. •► Led our Jan-Feb 2020 promotional Sales, with a 4x score: Total Team Sales : £1500, Personal Sales : £580, Team of 12.

    Factory (Operations) Accounts AnalystBakkavor
     - London, United KingdomFull Time
    • In this role, I was reporting our factory’s Daily Labour Efficiency and Weekly Material Variances, directly to the Lead Management Accountant - also (among others) to the Head of Finance and the General Manager. (i) Daily Labour Efficiency: - I was auditing our Finished Goods production data, as scanned by Operations. (by reconciling orders, wastage, shortages - and computer stock VS. the planned closing stock) - I was then announcing the correct Volumes of the previous day’s Finished Goods Production. - I was also performing the analysis of the difference between standard VS. actual hours, as related to the categories of goods. (ii) Mid-week and Final Material Variances reports: - I was accounting for all the variances (Raw Materials, Lab samples, Packaging, Consumables, etc.) in our production process. - I was forecasting the Weekly Variances and writing the commentary on the main drivers of our Rejections (Raw Mats., Work-in-Progress, FG) and Unexplained. My close collaboration with the Planners & Procurement, Goods-in and the Operations Dpt, was key for the investigation of variances not in line with the trend. •• By accurately setting up the recipes/costs of our main site’s products in the Bill of Materials (BOM), I ensured the minimization of system-related variances. ••• I had been trusted with the update & improvement of various MS Excel trackers - which practically made an impact in the Senior team’s decision-making. ► Top achievements: 1) Praised by the Head of Finance as a “Mammoth undertaking”, our team managed to setup materials/costs for 121 product recipes in 16 weeks; 279% as efficient, if compared to the previous record held of 141/year. This was a project for TESCO. 2) By compiling all my notes, I created several handbooks (screenshot-illustrated), documenting the SOPs (Standard Operating Procedures) of my role, in detail. The above manuals met great success, as they significantly supported my new colleagues during training.
