A passionate tech enthusiast building secure, reliable backend systems with expertise in PKI, Certificate Lifecycle Management, and cryptography workflows — currently exploring agentic AI systems.
I am a Software Development Engineer at AppViewX, specializing in Certificate Lifecycle Management (CLM), PKI, and security-focused backend systems.
With strong hands-on experience in cryptography workflows, certificate automation, backend platforms. I design systems that handle certificate management at scale — implementing security protocols and automating complex identity workflows across enterprise environments, while exploring agentic AI systems.
Beyond work, I'm a passionate tech enthusiast at heart. I love exploring emerging technologies across software, science, and space — from installing and experimenting with custom ROMs and Linux distros to staying up to date with the latest breakthroughs in tech and beyond. Technology isn't just my career — it's a genuine passion I live and breathe.
Building systems with security at the core, from PKI implementations to cryptographic workflows.
Writing maintainable, scalable code that stands the test of time and growing requirements.
Designing solutions that work across diverse enterprise environments and scale.

Architected and built a production-grade Certificate Authority for IoT environments, owning the system end-to-end from design to deployment. Worked with PKCS#11-based hardware security, integrated Azure IoT Hub and deployed scalable infrastructure on Google Kubernetes Engine, developing strong expertise in PKI systems.
Integrated WAEP to facilitate MSCA to AppViewX CA migrations. Developed deep expertise and performed extensive troubleshooting across ADCS, Windows AD Domain, and multi-forest environments
Engineered enterprise-scale automation by customizing ACME clients (Go, Python, PowerShell, C#). Worked extensively on MS-Intune EST, SCEP, ACME, and CMP protocols.
Developed a unified agent for Linux, Windows, and macOS that discovers, renews, and replaces all types of certificates across the entire machine automatically; enabled scalable deployments using Ansible across Azure VMs.
Developed a CA-agnostic certificate simulator, significantly reducing licensing costs while cutting dependencies and accelerating performance testing.
Expanded CA integrations across auto-enrollment protocols, enabling support for multiple Certificate Authorities and improving interoperability, scalability, and centralized certificate management across diverse environments.
Boosted test coverage significantly: integration tests from 0 → 85% and unit tests from 50% → 85% across all auto-enrollment protocol projects.
Revamped audit logs and improved CLM integrations, optimizing platform-wide reporting workflows.
Revamped the auto-enrollment licensing model, reducing dependencies and accelerating performance.

Built an autonomous CI/CD security pipeline that detects vulnerabilities using Semgrep SAST and automatically remediates them using a team of six specialized AI agents, powered by Devstral on Ollama Cloud. The system is orchestrated via GitHub Actions, with an iterative review loop and live PR summaries showing before-and-after vulnerability counts.

Developed an AI-powered CLI tool using AWS EC2 and Amazon Bedrock that converts natural language into terminal commands. Integrates with Claude models and supports multi-step tasks (e.g., install Kubernetes, deploy Nginx, and delete it), with guarded execution (Safe Mode by default) and an optional unsafe mode for controlled flexibility.
Exploring practical AI applications, multi-agent systems, LLM integrations, and building intelligent developer tools.
Deepening knowledge in Go's runtime, performance optimization, and advanced patterns.
Mastering distributed systems, scalability patterns, and architectural best practices.
Preparing for the future of security with quantum-resistant algorithms and implementations.
Building secure, compliant platforms that protect enterprise infrastructure.
