Datacultr Pvt. Ltd., Gurgaon, India
Projects: Datacultr provides smartphone-as-a-tool-services on risk
reduction for new credit lines to customers, with over 20m+ users and
60m+ logins daily. I’m leading an agile team of 4 setting up, configuring,
and securing 15+ AWS cloud services, laying stress on open
communication, and providing continuous feedback. I improve, manage,

(servers + logs), security (infra + apps), compliance, and Data Loss
Prevention measures. So far I have created 30 servers out of 45, 3
Classic Load Balancers, 3 RDS, 2 ElastiCache with Redis engine, 2 EFS,
Guard Duty, 30 encrypted volumes (Encryption at Rest), SSL
(Encryption in-transit), 30 SG, cost optimization setup for production and
lower environments. Worked on IasC via Terraform, CasC via Ansible,
JCasC via Jenkins, and shell scripts. Reduced latency in load balancers
by 100sec by optimizing Nginx reverse proxy servers configuration to
process over 60m requests per day. Optimized processes and threads
for a Python app based on uWSGI to provide more compute and
throughput. Eradicated and secured (App + DB) 3 types of attacker
viruses, files, and CRONs on 7 impacted prod and lower environment
servers. Also successfully led a cloud migration project from Azure to
AWS by using automated migration tools & manual setup within 3 weeks
(critical deadline). Reduced VMs footprint from 75 to 31, following best
practices and AWS Well-Architected 5 pillars principles. Technologies
