PROFESSIONAL EXPERIENCE
1. “Senior Software Architect” in EnterpriseDB from Jan 2011 till now.
Primary job responsibilities:
a) Supporting main architecture design decisions.
b) Implementation of different software modules.
c) Provide support to development team members.
Major Projects:
EDB Replicate
Replicate is a multi-master logical replication solution for PostgreSQL.
I was responsible for the following modules:
• Propose the design and implement system for replicating logical replication slots across physical replicas.
• Propose and do POCs for ways to reduce un-necessary network traffic to increase performance.
• Propose ways to detect, log and handle UPDATE-UPDATE conflicts.
Migration Portal
Migration portal is a web based application to port an oracle database to EnterpriseDB Advanced Database Server (EDBAS).
I was responsible for the following activities:
• Implement repair handlers using RegEx to transform Oracle SQL constructs to equivalent constructs in EDBAS on the fly.
2. “System Architect” in TeleSehat Private Limited from March 2009 to Jan 2011.
Primary job responsibilities:
▪ Overall architecture design of the Tele-medicine product.
▪ Provide support to the business development, HR and other activities.
Major Projects:
Dynamic Bandwidth Aggregation Router
DBAG router is provided more than one internet connections. Devices needing internet connect to the DBAG router. The DBAG router provides failover and load balancing.
I was responsible for the following activities:
• Proposal Preparation and Submission for funding.
• Feature comparison with existing solutions available.
• POC for the main design of bandwidth aggregation router. The POC consisted of a RTP voice sender and a RTP voice receiver. Two different internet connections were provided to the aggregation router. Both failover and load balancing with 1:1 ratio were demonstrated to work successfully in the POC.
• Project progress reporting to the funding agency.
Standards Compliant Semantic Electronic Medical Record and Device
Interoperability Framework
The aim of the project was to create HL-7 compliant medical record system.
My role in this project was to decode the byte stream sent by medical lab test machines on serial port or ethernet. I was then required to create simulators for the machines so that the rest of the system can be tested with different values of the medical test results. We were able to integrate different blood test machines, urine test machine, blood chemistry analyzers etc. I was also responsible for deploying the system in the field for evaluating the user experience.
