Amvik Solutions, Senior Software Developer(Consultant) & L2 Tech Support, Oct 2017 ~ Apr 2019

I was hired by Amvik as a software developer and L2 Tech support, this company deals in Behavioral Therapy. The product is a semi-SAAS which provides operational utility for therapy centers to schedule, log, track,audit their patients(esp kids with autism therapy requirements). The big part of the application was the Billing & Insurance Claims module which was an added service module which helped the clients in illing and insurance claims. It has lot of critical areas and high demand reporting with security which I was responsible. I joined them with a 3 member development team so here I was entitles for self driven work and approach. I had to communicate actively with clients, sort issues and push them to JIRA(major or minor). Due to the increased load, I was responsible to setup DevOPS and implement QA cycle. I also interviewed a large number of tech candidates and helped setup the dev center in Noida, India.

Activ4Pets, Consultant Product Manager, Apr 2017 ~ Sep 2017

I was engaged as the Product Manager for the B2C product which was healthcare for pets and animals which included 8 distinct modules right from PHR to E-consultation. I was managing the product features and enhancement. The entire 22 member dev team was under my direction. I successfully implemented Dev Ops for continous deployment of web apis and integration with individual android and IoS apps which were scheduled into weekly minor builds and major build deployments. I also envisaged product feature with management, marketing team and setup goals and tasks, implemented scrum methods for production and operations. I got a big exposure to my balance on management + tech supervision skills.
I had to leave the company due to personal reasons when we just started with IoT enabled pet tagging devices, we were about to start collaboration with a startup in bangalore who were actively into the tagging device area. 

Ridgehead LLC, Software Consultant, Jan 2014 ~ Mar 2017

In my tenure with Ridgehead, I was working as a third party senior developer for NetApp USA across various projects and was actively involved in having direct communication with NetApp Business Heads, capturing requirements, designing TDD, application architecture, development & delivery. I am listing out the project that I had worked on during this tenure. 
  • Net2-RMA(Asset-Recovery)
    This tool is used by NetApp to track parts that have not been returned by clients that have either asked for servicing and simply not returned the defective hardware or in cases where historical data is inaccurate and requires to be consolidated. The system also allows CSRs to track their interactions with clients so as to provide an audit trail for follow-up should it be necessary. The entire process for this was manual before it was converted to a system that does not require user-intervention when items are returned or their status is changed. The key integration points in this system are SAP, Oracle and the Reporting System (SQL) from which data is gathered and automatically transformed to provide value to the client for tracking and re-acquiring their hardware. The system also provides a robust search interface for granular as well as macro search capabilities where necessary.

  • CSS-Track
    This is a CRM tool used to track work/projects in the form of tickets that can be administered by project administrators. The tool also has a workflow feature which allows administrator users to create workflows for tickets based on user-interactions as well as system triggers. It was originally written with a SQL back-end but is currently in the process of moving to a MongoDB back-end. I was actively involved in stabilizing the application and porting the backend to MongoDB. The complexity of the application was it was a legacy application built on core asp.net and used server controls as well as html controls; data was relational and had runtime performance issues due to huge data and multiple workflows running in the background.

  • Net2 Scripting
    This application was intended to allow field engineers to access the work process script, a method/manual description on how to diagnose an equipment. Primarily the challenge was to have an offline application that can be viewed in handheld devices as this application had to enter secure and de-militarized zones where there would be no access to internet. The application vastly used json as local file and javascript, on returning to connectivity the application will auto-sync the remote data to the live servers. This application also had a javascript based rules engine that would make decisions based on inputs. The application was deployed using JBOSS as we had some data from soap APIs from java environments and some were WCF.
