The most amazing...
...web portal I've developed is for reporting and forecasting weather. It helps various municipalities manage their documentation of weather-related operations.
Work Experience
Web Developer
Arotahi Agribusiness
- Added geospatial map view to the portal, allowing users to draw property areas, fetch different property classes from the database, or utilize APIs to retrieve government-defined mappings.
- Enabled users to either draw boundaries manually or copy polygons from government mappings to define their legal property boundaries.
- Provided functionality for users to create mappings within their legal boundaries, such as defining slope areas or land improvements on their real estate.
- Allowed users to cut, copy, and paste features across different layers, giving them the flexibility to build and reuse existing boundaries for their real estate mappings.
- Enabled users to process all their operations, check the land breakdown of their land areas divided into sub-sections, and finalize the breakdown. Alternatively, they could pro-rata the calculations to keep the final total to the actual value.
Amplify and GraphQL Developer
Global FoodService Inc
- Created an Amazon Personalize dataset with a user personalization recipe to provide personalized search results according to user interactions in the past.
- Crafted another solution in Amazon Personalize with a Personalized-Ranking recipe and a search pipeline on the Amazon OpenSearch domain to provide a re-ranking of OpenSearch results based on past user interactions.
- Used OpenAI text moderation chain to automate user review moderation and used Amazon Simple Email Service (SES) to inform admin when a review was flagged inappropriate.
Full-stack Developer
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).

- Developed portals as a junior developer under a senior lead.
- Learned basic programming techniques and coding conventions while working on actual code.
Experience
Winter Web App
http://winterwebapp.ograapps.comThe 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
http://portal.mtspro.ioThe 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
• 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.
