Currently between roles and available to join immediately.

MCA from B.M.S College of Engineering, Bengaluru (2020–2022), and BCA from KLE Society’s Nijalingappa College, Bengaluru (2017–2020).

Professional Experience

#

DevOps Engineer — Colligence Research Pvt. Ltd.

#

Nov 2023 – Jul 2026 | Bengaluru, India Internal transfer from sister company Appsndevices Technologies

CI/CD & Release Engineering

• Designed and maintained CI/CD pipelines primarily using GitHub Actions (primary) and Jenkins — shipping daily releases to Android, iOS, Windows, and macOS from a single codebase
• Built automated deployment workflows serving a team of 10+ engineers, using blue-green and canary rollouts for staged release promotion, reducing manual deployment effort and improving release consistency across all platforms
• Managed secrets across pipelines using GitHub Secrets, Infisical, and Google Secret Manager

Infrastructure & Cloud

• Managed cloud infrastructure across DigitalOcean (Droplets, networking, S3-compatible storage), Google Cloud Platform (BigQuery, data streaming, Compute Engine), and AWS (EC2, S3, IAM, VPC, Lambda)
• Provisioned infrastructure using Pulumi (primary IaC tool), with experience in Terraform and Ansible for reproducible, version-controlled environments
• Performed cloud cost optimization — right-sizing instances, cleaning up unused resources, and reducing infrastructure spend
• Used Redis for caching and application performance optimization

Networking & Security

• Configured Nginx reverse proxies for application routing and load distribution
• Managed DNS records across Cloudflare and cloud provider DNS services
• Set up and automated SSL/TLS certificates (Let’s Encrypt) for secure HTTPS across services
• Configured firewalls and security groups — iptables, UFW, and cloud provider security lists/ACLs
• Managed IAM and RBAC policies across cloud providers for least-privilege access control

Containers & Orchestration

• Managed Docker-based build environments and Kubernetes deployments ensuring scalable and stable application releases
• Deployed and maintained multiple containerized services in production

Monitoring, Logging & Reliability

• Set up and maintained Prometheus + Grafana monitoring stacks — configured exporters, built dashboards, defined alert rules, and used them to identify performance bottlenecks in production
• Built centralized log aggregation with Loki, and used CloudWatch and cloud-native logging for centralized log management
• Built disaster recovery and backup automation — automated database backups, tested restore procedures, and maintained DR documentation
• Authored operational runbooks and documentation for incident response and system maintenance
• Supported production environments through on-call rotations, resolving CI/CD and infrastructure-related incidents with root cause analysis
• Managed cron jobs and scheduled automation for maintenance tasks, cleanup, and health checks

AI-Assisted Engineering

• Hands-on practitioner of Claude Code for agentic coding workflows — using AI agents for scripting, debugging, configuration generation, code review, and operational analysis
• Experience with prompt engineering and agentic coding patterns — designing effective prompts for complex multi-step automation tasks, validating AI outputs for correctness and reliability
• Early adopter of AI-assisted DevOps: using AI tools not as a crutch, but as a force multiplier for engineering velocity

Process & Collaboration

• Collaborated with development, QA, and product teams in Agile (Scrum/Kanban) workflows
• Participated in sprint planning, delivering DevOps automation improvements within sprint cycles

Database Engineer — Appsndevices Technologies Pvt. Ltd.

#

Nov 2022 – Nov 2023 | Bengaluru, India

• Administered production PostgreSQL — streaming replication (including logical replication with dump/restore extensions), automated backups with restore testing, and performance tuning for high availability
• Managed Apache Kafka clusters for distributed event streaming — troubleshooting replication, connector, and consumer pipeline issues
• Built event-streaming and log-aggregation pipelines feeding Google BigQuery analytics
• Designed schemas and optimized complex SQL queries for application and reporting workloads
