My Notable Projects
Health insurance companies has to spend a lot of time and effort in evaluating health care costs and using that to determine the premium that they have to charge. Similarly, insurance companies in other sectors too have to closely monitor the costs which they have promised to cover. Alternately, if insurance companies end up overpricing the amount they charge their investors, then it is only natural that these investors will prefer to be insured by their competitors.
I created an insurance pricing forecast system using MySQL queries, trigger, stored procedure for a Miami based health insurance company which helps them in forecasting a competitive insurance price to their customers.
Sales for a certain product vary based on several factors. Some of these factors include seasonality, locality, reduced competition, advertisements and promotions. For good inventory management, it is very important for a store to have a predicted estimate on sales for various products on sale. I created a sales forecasting system for Pavilions (A california based grocery chain) which helps them in getting a better understanding of which of its products are in demand and predicting their monthly, quaterly and yearly revenue and profits. The predicted data also helps them in better inventory management.
I worked on tcg website which is designed using php, mysql and bootstrap. This website was designed for a client who wants to store all of his employees data at one place and where his/her employees can rate each other every month. In this website I add the functionality of registration and login. After login users can add their info and can rate each other works every month. I also add the functionality where they will be notified each month through sms to rate each other.
107taste.com is a restaurant based in Miami. They wanted a simple neat and clean information sharing website
which can show their brand presence online effectively. I created a website and use some local search engine optimization technique which helps them in attracting around 350000 visitors in last 2 years (google analytics report). To generate same amount of traffic through google ads they have to spend around $500K cad as usually in restaurant industry Google adsense charge around $1.7 to $2 cad per click.
Cajunboil.com is a seafood restaurant based in Miami. They wanted to integrate online ordering system and some help in improving their brand presence online. I helped them in attracting around 418000 visitors in last 2 years (google analytics report).
