I’m a DevOps Engineer with over 7 years of hands-on experience in the dynamic
intersection of development and operations. Possessing a Master's degree in Computer
Science, my journey started in QA, where I honed my skills in ensuring software quality
and reliability. However, I found my true calling in the DevOps domain. This transition
allowed me to merge my early QA experiences with a growing expertise in DevOps
practices, resulting in a unique skill set that combines quality-focused thinking with an
automation-driven approach to software delivery.
I’m have a lot of experience with Kubernetes and also hold the title Kubestronaut which means that I passed all the available Kubernetes certifications.
I’m also a passionate Copy writer who mostly likes to write about tech-related content and also about fitness and health.
I’m open to part-time project in the field of Copy writing as well as DevOps.

I help SaaS, ecommerce, and online platforms stop abusive traffic, protect APIs, and keep Cloudflare and AWS infrastructure stable during attacks and traffic spikes.
My primary specialization is Cloudflare and AWS security architecture. I build systems where authentication, rate limiting, traffic inspection, and abuse prevention happen at the edge or API layer rather than after malicious requests reach application servers.
TYPICAL ENGAGEMENTS
• Cloudflare WAF, DDoS protection, bot management, and rate-limiting architecture
• Cloudflare Workers development for authentication, request validation, routing, and abuse control
• API protection using JWT, HMAC, mTLS, schema validation, and traffic shaping
• AWS Lambda and API Gateway architecture for secure serverless applications
• Cloud infrastructure audits, migrations, hardening, and cost optimization
• Terraform-based infrastructure for repeatable and auditable deployments
• Incident investigation using Cloudflare logs, AWS logs, and observability platforms
• Ongoing infrastructure ownership, monitoring, optimization, and incident response
CLOUDFLARE ARCHITECTURE
I use Cloudflare Workers, WAF rules, Rate Limiting, Bot Management, KV, Durable Objects, R2, Queues, Load Balancing, and Zero Trust to build security controls close to the source of traffic.
Examples include:
• Validating JWT or HMAC credentials before requests reach backend infrastructure
• Detecting abusive behavior using ASN, IP, fingerprint, request, and session signals
• Maintaining dynamic blocklists and traffic thresholds during active attacks
• Tracking per-client or per-session abuse using Durable Objects
• Serving content through R2 or edge caching to reduce origin exposure
• Protecting APIs without blocking legitimate users or search-engine traffic
AWS AND SERVERLESS SYSTEMS
I design AWS Lambda and API Gateway workloads with controlled execution, predictable scaling, and limited infrastructure exposure.
This includes:
• Request validation before compute-intensive application processing
• Authentication and authorization enforcement
• Event-driven logging, alerting, and security automation
• CloudWatch monitoring and incident investigation
• DynamoDB, S3, IAM, and Lambda integrations
• Terraform-managed AWS infrastructure
BROADER DEVOPS CAPABILITIES
• Linux infrastructure administration and hardening
• Docker, Kubernetes, and OpenShift
• CI/CD using GitHub Actions, Jenkins, Tekton, and Travis CI
• Terraform and Ansible automation
• AWS, Google Cloud, IBM Cloud, and hybrid environments
• Prometheus, Grafana, New Relic, Nagios, and Cloudflare Analytics
• WordPress and Magento infrastructure, performance, and security
I work on both defined projects and long-term retainers. Engagements can cover architecture, implementation, security reviews, emergency incidents, or ongoing responsibility for production infrastructure.
