Full-stack Developer

2014 - 2022
VenExel Technologies
  • Started working as a back-end development-only engineer and later performed multiple roles, managing the architecture for the applications, overseeing junior resources, and managing DevOps and CI/CD pipelines.
  • Developed an app in Ruby on Rails to automate day-to-day operations covering extreme weather conditions, including an API for a mobile-facing app, a web portal, and UDP-based console device reporting. It helped municipalities handle their operations.
  • Handled multiple ongoing projects developed in Ruby on Rails and MEAN/MERN stack and worked on CI/CD pipelines, dealing with incoming updates and new features. Working closely with clients throughout.
  • Managed the app infrastructure end DevOps on AWS, including server-based and serverless environments, databases, and reporting. The major services include EC2, RDS, Aurora, Lambda, API Gateway, Cloud watch, and others.
  • Built a MEAN stack-based universally compatible salt-tracking system with ground speed control. Worked directly with the client in deciding the technology and architecture with decisions on DB selections to support the requirements in the best way.
  • Built GPS tracking apps in Ruby on Rails and MEAN stack that allows reporting for different types of end-users. Added reporting based on the tracking results to serve end-user requirements from reporting required operations to managing regular ones.
  • Integrated Google Maps APIs in multiple projects for Ruby on Rails and Angular for live GPS reporting and geofencing purposes. It enabled users to manage their workloads properly while knowing where they needed to put more effort.
  • Developed a completely serverless API in Node.js and deployed it on AWS Lambda. The API was built to keep it robust and accurate while performing complex operations within the provided time limits.
  • Deployed web servers on Heroku, EC2, and Elastic Beanstalk, depending upon needs. Initially, applications used Heroku, but with increasing requirements, they were moved to EC2, and even higher requirements were managed using EBS.
  • Integrated relational and NoSQL databases for different projects. Deployed databases on RDS, Heroku, and MongoDB Atlas. Migrated whole databases from one service to another when required (e.g., Heroku ended support of MongoDB, so moved it to Atlas).

Winter Web App

This Ruby on Rails web portal is developed for reporting and forecasting weather for municipalities to manage their documentation of weather-related operations every season. I focused on creating a well-structured system that is easy to use.

The client was an enterprise company working in operations for more than 120 years, with more than 400 municipal members.

The main goal was to automate operations documentation for a whole season, along with weather forecasting, reporting, and alerting the system for extreme weather.

It was a mega project with local governments being its target customers and data volume expected to be getting into TBs.

The development team consisted of up to ten members over time, with roles being divided into architect, developers, the QA team, and a manager.

I worked directly with the client to gather all the requirements and product delivery.

Built Weather tracking system and documentation systems as Rails Engines

The product was built keeping in mind the ability of end users, which could be in any age range up to 70 years.

MTS Pro: Universally Compatible Salt Tracking System

A MEAN stack-based future-centric app with a serverless API and Angular front end. The client was a non-government organization enabling customer organizations to automate salt tracking operations.

The project was built with a focus on extensibility and durability. The team that worked on the project was composed of four people with a sole architect/developer, graphics designer, QA, and manager. The app was extensible and could be integrated with any other similar app with minimal effort, as the API-based design was carefully crafted to allow this. A salt tracking console device was connected to the system, reporting GPS and salting information via HTTP. The system handled further reporting according to the end user's requirements. The technologies used in this system include a vast range of AWS services like Lambda, Cognito, CloudWatch, S3, etc.

Fieldwhiz: Fleet Management System

A Ruby on Rails, Angular, React, and AngularJS-based system for managing the fleet for contractors. The client was a private organization providing automation solutions for its customers. The team for the project had around 20 people, depending on the volume of deliverables. Some of the options included in the system were:

• IVR: Integrated a Twilio-based IVR and messaging system into the system that would help people perform tasks, such as setting up work orders and logging work hours against the work orders. The system was based on both Twilio IVR and messaging services.
• Salesforce integration: Integrated Salesforce fleet information for the clients into our system and vice versa.
• GPS tracking: An online real-time tracking system for the fleet with information regarding operations performed during patrol hours and suggestions for where improvements are needed.
• Real-time map plotting: Plotted whole patrol information on the map for reporting purposes.
• Routes/geofences defining: Defined geofences for operations to be performed within or outside of them.
• Work-orders management
• Cost calculations

My role varied from being a developer initially to an architect for new features and manager/mentor for junior developers.

Automated Vehicle Location System

A Ruby on Rails-based solution used by municipalities to manage their day-to-day operations of field patrol and material application. PostGIS was used in the project to handle a range of GIS-related queries and reporting. There was a live location map integrated and season-dependent reporting, like daily reports for summer and winter.

Asset Panda LLC

A Ruby on Rails app with Node.js-based serverless functions performing some operations. The Project is for multiple award-winning enterprise organizations. Worked as a part of the new website, and the role was to be part of a module for automations. The main part of the automation engine was in Ruby on Rails, with actions residing in Lambda based on a serverless framework.


A Ruby on Rails-based gifting platform.

I worked as a full-stack developer integrating new designs and features to make the portal look better. I also updated some features on the admin end to make tasks easier.
