Bio
Sarmad Ahmed
For more than a year that I worked with Kevin, I found him to extremely dedicated and passionate about data domain as he always delivered regardless the nature or the scale of the project that was thrown at him. One of the key testaments to Kevin's tech prowess; while working with a tech that was previously unknown to Careem, Kevin delivered a world-class ML based fraud detection and prediction project with great impact, that was later lauded by the data scientists and teams not just with in Careem but across the globe. Additionally Kevin's presentation, analysis along with managing multiple stakeholders across different domains is exemplary, a quality rarely seen in tech resources. Kevin, in short, with his dedication, passion and tech prowess would definitely be an asset to any data team across the globe.

Forecasting Tourist Visits to Dubai: - Collected multivariate data (such as FX rates, public holidays, airline capacities) which showed many correlations to the number of visitors to Dubai from several countries. - Built time series forecasting models to accurately predict the monthly visitors per country for the next 12 months. - Used a combination of SARIMAX, Facebook Prophet, XGBoost, and LSTM RNNs. Online Journey Attribution Modelling: - Analysis of the journeys that users took on the web when exposed to marketing campaigns. - We built attribution models to determine which campaigns were most effective at converting a user’s online browsing journey into a tourist visit to Dubai. Sales Incentive Program & Sales Forecasting: - Collecting, storing and processing vast amounts of data and KPIs pertaining to a large telecom company’s B2B customer-base, as well as sales attributes of individual salespeople - Building a complex sales incentive engine and forecasting models for future sales targets.

Data Science Accelerators: - Random Forest to determine which complaints filed to a bank are most probable to be escalated. - Industry-leading accuracy using XGBoost and Deep Learning to determine which loans are most likely to go into default. - Visual Research, which I led, uses AI to assist financial analysts. Built a custom data retrieval API and ingestion engine to build extensive datasets using both data internal to the financial markets, as well as alternative sources. These include companies’ fundamental figures, data metrics extracted through NLP techniques on their SEC filings, and macroeconomic data. The datasets are then fed through a stacked ensemble of LSTMs to forecast the performance of a given company’s stock price in the coming quarter. - A wealth management tool that leverages the predictions made by Visual Research, allowing wealth managers to provide valuable insights and intelligent recommendations to their clients. LIBOR Transition - LIBOR is the referenced floating rate used in an immense number of financial contracts (interest rate swaps, loans, mortgages, etc.), but it will be phased out in 2021. - Built a Data Science driven solution for contracts to be benchmarked against alternative rates, with historical and forecasted comparisons in a dashboard. - OCR is used to read documents, and we use NLP techniques to then extract all the relevant values from both structured and unstructured contracts. - A combinations of Named Entity Recognition, dependency parsing, and vector embeddings produced our best solution. Social AI: - NLP and Recommendation System project for a large bank. - Through profiling of the bank’s customers, a collection of advanced, in-house trained chatbots, and recommendation engines, we are creating an extremely personalized banking experience. - This experience would provide recommendations based on where the customer currently is, what their interests are, where they are travelling to, what they have scheduled, etc. Show less

I worked on two projects during my internship with Accenture: 1. Carrying out Deep Learning research within the internal Tech Labs team in The Dock through the use of LSTM Recurrent Neural Networks. 2. Member of the Data Analytics team on a client-site project where we were managing the composition of two large database systems required in the merging of two multinational Pharmaceutical companies. We followed an agile workflow implementing mocks and sprints in preparation for going into production. Show less

Aug 2016 - May 2017
I worked part-time alongside my studies in the Risk & Trading team as a Trader on live football games. My role as a Trader consisted mainly of the following: • Recognising and trading against arbitrage betting • Adjusting prices of markets where I deem necessary in order to maintain expected profit margins • Monitoring customers’ betting habits and either restricting/boosting their betting allowances • Reviewing related statistics linked to new, as well as restricted customers, in order to predict their future betting strategies • Calculating market overrounds and hence sufficient expected profit margins Show less
