DATA VIZ. ENGINEER

Calibrate Consulting, London, UK
October 2017 - June 2019


Data visualization consultant assigned to a variety of projects in Qlik Sense, JavaScript and Java. Project specifications & data sets varied from client to client. The typical end product was a DAR (dashboard, analytical & reporting) system that transformed big data from disconnected sources into a cohesive interface.

Most applications utilized Qlik as the database & association engine, JavaScript/CSS/D3 to design the interface & custom visualizations, then AWS to host the project. I worked end-to-end with heavy involvement in all stages of the development cycle:

  • Lead business analyst

  • Lead UI/UX designer

  • Software engineer

  • Producing testing suites and relevant documentation

  • Training users

Unfortunately delivered projects were confidential with clients, but below includes some of my early design concepts for the largest project I completed.

STATE-OWNED OIL & GAS COMPANY

Technologies used: JavaScript, D3, CSS, QlikSense

The majority of my time with Calibrate was spent serving the national oil & gas company of Algeria - the largest company in Africa. We were commissioned by and coordinated directly with the CEO & his team of executives to design DAR systems that would track the company’s progress against its growth objectives.

The company is vast with many hierarchical structures throughout the country, each with its own process in collecting data and reporting to its parent branch. As data analysts, Calibrate was responsible for collecting data files as close to these remote sources as possible, and then collating all of this information into the equivalent summaries provided by pre-existing executive reports.

PHASE 1

My first large project with Calibrate Consulting, not long after I joined them as a graduate. I was assigned to the project in a junior role to assist in a team of 4 (the CEO of our company, a senior engineer & a project manager) and we traveled to Algiers weekly to work at the client’s HQ.

The project was approximately 9 months in length, with the objective being to design 2 DAR systems. One analyzed the production, sales, transportation (and more) of their key products, while the other tracked projects & investments against target yields and key deadlines.

The scale of the project was very large for the team size, and as the individual who travelled to Algeria the most, I soon became in a position of being the most knowledgeable about the company’s vast data, the desired end product, and key visualizations to communicate their needs in a simple manner. As such, I had high oversight on all areas of the product until the release.

PHASE 2

Given my significant role in the first phase, I was assigned to Phase 2 in a lead position from the start.

The CEO desired the addition of 4 more dashboards detailing information from Finance, HR, Health & Safety, and Strategic KPIs. A portal was also included to serve as the homepage and provide access to the varying dashboards.

Again I worked as a lead business analyst, helping the client to determine their needs and make sense of data sources at the HQ in Algeria. Then I served as the lead UI/UX designer as well as a software engineer.

This project was larger than the first phase and so required a larger team of UK staff to assist, and so I coordinated with many departments to make sure that the requirements of the project were being met.

OTHER PROJECTS

INTERNAL HR/OPS AUTOMATION

Technologies used: JavaScript, CSS, AWS, Google app scripts, node.js & web scraping

A self-managed, internal project for our COO to automate the on-boarding of employees. Utilized APIs to create a Gmail account (from the acquired HR data) and then initiated user accounts for all other services via their unique APIs (Replicon, Slack, Atlassian, Xero, BreatheHR).

BRITISH NHS (NATIONAL HEALTH SERVICE)

Technologies used: JavaScript, CSS, Qlik

An independently created app for a client working in the British NHS. They wished to be able to effectively communicate the cost benefit of their unique staffing model, which paired special experts alongside standard GPs to resolve the complex conditions of elderly patients more effectively at a single location (rather than sending them to multiple which could delay treatment or diagnosis - potentially increasing the severity of the issue and costing the government more money). The client was able to use the app that I created to make their case, and the model is now being rolled throughout other areas of the NHS.

LOCAL PRIMARY SCHOOL

Technologies used: JavaScript, CSS, Qlik

A self-governed project working with a local school to help track classes against targets set nationally, regionally and by the school itself for grade distribution. Pupils were also tracked as individuals against their own track record and goals set by their teacher.

SAMSUNG

Technologies used: JavaScript, CSS, Qlik

Brought on-site to enhance the UI/UX design of an application and the associated data visualizations being produced by a coworker.
