Executive Summary
Continuing the development of a musician networking platform which involved implementing new features, enhancing the existing ones, and fixing bugs/errors/issues in the platform by improving its efficiency and productivity along with making the platform responsive.
Problem Statement
Our client wanted us to design and create a social platform where each and every user is able to connect and interact with one another easily. He came to us after a bad experience with some other company and was expecting to continue the development by improving website performance as well as efficiency.
The platform had various bugs which needed to be fixed and some major features were to be added like payment service, OTP service, adding more security along with improving existing features. Performance of platform was being affected as there were some major issues like:
1. Deployment architecture- Everything was deployed on a single EC2 instance due to which there was a high amount of downtime. The performance was impacted more when the user base was increased.
2. The videos on his platform were taking a lot of time to load.
Our Solutions
1) We followed MVC architecture for developing REST API using express as middleware and mongoose for managing data in MongoDB. Authenticated API with jwt by using JSON web token package.
2) Added payment service in the platform by integrating stripe payment gateway with help of stripe package, created OTPs for security/validation which was communicated via SMS with help of Twilio.
3) To improve the performance, we deployed the backend on a separate ec2 instance with Nginx as reverse proxy and pm2 as process manager which comes with a built-in load balancer and helps to keep the application alive forever.
4) Installed Nginx on the server, and changed the Nginx.conf file configurations as per the requirement and it worked as a load balancing solution. Also replaced the lets encrypt SSL certificates with ACM(AWS Certificate Manager) to make certificate renewal, provision, and management process better as well as easy.
5) For adding new features to the platform, the frontend involved creating several components, services, directives, pipes, and modules in Angular.
6) To reduce the load time we implemented Lazy loading with help of Lazy load routes. The reason behind increased load time for videos was the use of video tag over secured protocol, to solve this we used iframe for rendering videos which proved to be much faster.
7) Changed the existing deployment architecture and moved the front-end to S3 so that load on the server can be reduced. We moved the front-end to S3 with CloudFront as CDN for speeding up the distribution of web content and improving performance.
Technologies
Angular 10, Node, Express, MongoDB, AWS S3, EC2, CloudFront
Success Metrics
1. Provided all the deliverables within the expected deadlines, improved performance as down time reduced and videos were no longer buffering for a long time.
2. Met all the expectations of the client and with positive feedback. All his meetings with directors and students were successful due to which he wanted us to implement some more new features on his platform.
3. Continuous reporting of progress to the client.

Project Summary
PXL is an open source social network platform for content creators. It enables users to create public or private spaces for any use such as any particular task base space or any other. Furthermore, users can take advantage of social features such as building connections, posting projects that pique the interest of other users, adding team members, notifications, project participation, and more. They can also manage their profiles and conduct a global search. This social network tool offers an online version where anyone can experience this free tool. PXL’s user interface is very logical, and users can easily navigate through various elements.
Problem Statement
The client’s requirement was to build a full-fledged backend application that can easily integrate with their prebuilt front-end application, and he later asked us to integrate the backend with the front-end.
We had to design and create a social platform where users can showcase their inventions and gain exposure. One can post any software project, categorize them, invite team members, and also participate in other projects.
Additionally, to meet the need for significant content uploads, a solution had to be developed that could easily handle the upload of media files while still being affordable and effective.
We also had to create a real-time notification system that monitors all network activity such as accepting requests, declining requests, and being removed from one’s network.
Our Solution
- With thorough testing, responsive design, and increased efficiency and performance, we concentrated on completing each task as effectively as we could.
- Based on the client’s requirements, we used S3 bucket, RDS, EC2, and flask microservice for media files and SES for emails.
- Amazon S3 was used for file hosting and data persistence.
– Amazon Relational Database Service (RDS) was used for database deployment as it simplifies the creation, operation, management, and scaling of relational databases.
– Amazon EC2 was used for code deployment because it offers a simple web service interface for scalable application deployment. - We sent emails using Amazon SES because it is a simple and cost-effective way to send and receive emails using your own email addresses and domains.
- Django-graphQL was used for the backend, and Next.js was used for the front end. Django includes a built-in object-relational mapping layer (ORM) for interacting with application data from various relational databases.
– GraphQL aims to automate backend APIs by providing type-strict query language and a single API Endpoint where you can query all information that you need and trigger mutations to send data to the backend.
– Next.js offers the best server-side rendering and static website development solutions. We utilized the flask microservice to help with high content uploads since flask upload files give your application the flexibility and efficiency to manage file uploading and serving. - Using Github’s automated CI/CD pipeline we have triggers for code lookup and deployment.
Technologies
Django-GraphQL, Next.js, PostgreSQL, AWS S3, EC2, SES and RDS
Success Metrics
- All deliverables were completed on time and exceeded expectations.
- Met all the expectations of the client and with positive feedback.
- The client was constantly updated on the status of the project.
About
A non-profit healthcare insurance provider that encountered difficulties in managing the high volume of data on their on-premises system, which impeded their capacity to analyze that data efficiently to make informed business decisions. To address these issues, they chose to migrate their data to Amazon Redshift.
Business Challenge
As their business grew, the insurance provider faced several challenges with their legacy system. Most importantly, their on-prem data warehouse, Oracle Exadata, required significant time and resources to administer, especially for large datasets. Additionally, the financial costs associated with building, maintaining, and growing self-managed, on premises data warehouses are very high.
In order to manage costs, keep ETL complexity low, and deliver acceptable performance, the customer had to constantly trade-off what data to load into the data warehouse and what data to archive in storage.
Technical Challenge
The customer’s data pipeline followed a collect, store, process/analyze, and consume model, leveraging multiple AWS services. Their data lake was created in an Amazon S3 bucket, and the data lake's stored data can be queried using dbt, utilizing AWS Glue Data Catalog Databases and Crawlers.We recommended Amazon Redshift and Redshift Spectrum to build their data warehouse. After mapping the data with Redshift Spectrum, Amazon Redshift processes the data to Redshift tables. Data is then visualized and consumed by users through Amazon QuickSight.
AWS Services Adopted for this Solution
- Amazon S3, for data lakes
- AWS Glue, as a data datalog
- Amazon Redshift, as a data warehouse
- Amazon Quicksight, for data visualization
Data Processing Solution for Healthcare Organization
Amazon Redshift's scalability and flexibility make it easy to manage expanding data volumes effortlessly.

Redshift also provides a centralized and secure data storage solution, that also automatically patches and backs up the data warehouse, storing backups for a user-defined retention period. This replication and continuous backups enhance availability and improve data durability, and can automatically recover from component and node failures.
Amazon Redshift’s parallel processing and compression capabilities accelerate command execution, enabling it to operate on billions of rows simultaneously. Redshift Spectrum integrates seamlessly with other AWS services (such as Glue), making it easy to build end-to-end data pipelines. This ensures that data is always up-to-date, accurate, and secure.
“Before moving to Amazon Redshift, our engineering team was spending too much time managing our on-prem data warehouse. Now, we are saving so much time on data management, and our data analysis has improved significantly.”
- CIO, Healthcare Insurance Provider

Project Summary
Creating a Marketing website using ReactJS and AWS for the client to showcase what they do and how they do.
Feature enhancement in an existing web application where people with disabilities can request a communication facilitator or a support service provider and providers can accept a request and receive payment.
Problem Statement
The client divided the project into several MVPs.
As part of MVP-1, the client wanted to create a marketing website that is fast, secure, and allows people to understand what Mizaru is and how it can benefit them. They wanted a website that performs operations faster, is secure from the bots, and is cheaper to maintain.
MVP-2 involved enhancing the client’s existing web application, which was previously very basic. They wanted to implement features like admin dashboard management, QR code-based check-in and check-out of providers to provide service, etc.
In MVP-3 they wanted us to create a mobile application to perform the same functionality.
Our Solutions
1) We created a marketing website for the users using ReactJS. This provides us with a faster way to create and serve the application.
2) For deployment and maintenance, we used AWS. It reduced our cost and maintenance efforts.
3) For enhanced security from bots, we’ve implemented google ReCaptcha v3.
4) Once the user has a clear understanding, they are moved to a web app or a mobile App.
5) Through the web app customers (People with disability) can create a request based on their requirements (e.g. Need a communication facilitator or support service provider). Our application provides a way for people with disabilities to connect with service providers. This request will be visible to multiple service providers in the network and they can choose to accept or reject the request.
6) We integrated a payment gateway for processing the payment. Also, both customers and providers get notified of the multiple events. We created a dashboard for Admins to see the track of various requests and generate reports as per their needs.
