WORK HISTORY
Site Reliability Engineer @9fin
Project: AI platform to aggregate and analyze large scale market data to power high stakes decision making Embedded security controls into CI/CD pipelines, integrating SAST, dependency scanning, and container image scanning into every build Designed and maintained secure AWS infrastructure using Terraform, enforcing least-privilege IAM policies and environment isolation Partnered with engineering teams to implement secure-by-default patterns for Python services, APIs, and data ingestion pipelines Led container security initiatives across Docker and Kubernetes, including image hardening, runtime policies, and admission controls Implemented secrets management using AWS Secrets Manager and IAM roles, eliminating long-lived credentials from application configs Built security monitoring and alerting around cloud activity, application logs, and infrastructure events to detect anomalous behavior early Supported compliance and audit requirements by improving logging, access controls, and evidence collection across production systems Hardened CI runners and build environments to reduce supply-chain risk and prevent credential leakage during pipeline execution Worked closely with data and platform teams to secure large-scale data pipelines, ensuring encryption in transit and at rest Introduced automated security checks into Terraform workflows to catch misconfigurations before deployment Participated in threat modeling and design reviews for new platform features, balancing delivery speed with security risk Investigated and responded to security incidents and vulnerability disclosures, coordinating remediation with engineering teams Improved Kubernetes network policies and service-to-service authentication to reduce lateral movement within clusters Acted as a security advocate within the engineering org, providing guidance, documentation, and pragmatic security standards

ABOUT ADITYA K
DevOps & SRE with 7+ years of experience building, securing, and operating cloud-native platforms across fintech, healthcare, and large-scale banking systems. I specialize in designing secure-by-default AWS infrastructures using Terraform, embedding security controls into CI/CD pipelines, and hardening containerized workloads across Docker and Kubernetes environments.Currently working on AI-driven financial data platforms, I focus on integrating SAST, dependency scanning, container security, and IAM best practices directly into engineering workflows. My approach balances speed, scalability, and compliance—ensuring security is an enabler, not a bottleneck.Previously, I supported mission-critical core banking systems serving over a billion customers, where I automated deployments, optimized legacy COBOL systems, implemented monitoring with Prometheus and Grafana, and strengthened infrastructure reliability using Ansible and Jenkins. I’ve also contributed as a backend Python developer, giving me a strong application-level understanding that enhances my DevSecOps decisions.I thrive in regulated environments, collaborate closely with engineering and data teams, and bring a pragmatic security mindset to fast-moving product organizations. My goal is simple: build resilient, scalable platforms where security, automation, and reliability are deeply integrated from day one.
