Dawrix - Intelligent IAM & Security Gateway

2025

Centralized identity and authorization broker that enforces strict security boundaries and injects credentials for microservices and AI agent workloads.

[The Challenge]Microservices and autonomous services frequently leak credentials or lack centralized role-based authorization controls.
[The Architecture]Architected a zero-trust IAM gateway brokering OpenID tokens, enforcing fine-grained policies, and rotating secrets dynamically.
[Quantifiable Impact]Zero credential leaks, centralized audit visibility, and compliance-ready access logs across all connected services.

Clouds In Click - Multi-Cloud VM Provisioning

2025

Automated multi-cloud VM provisioning platform with self-hosted CI/CD agents, DNS orchestration, and cost-controlled resource scheduling.

[The Challenge]Provisioning isolated multi-cloud environments for developers was manual, taking hours and causing cloud budget overruns.
[The Architecture]Codified infrastructure with modular Terraform, automated Azure DevOps agent registration, and integrated scheduled teardowns.
[Quantifiable Impact]Cut environment provisioning from 2 hours to under 3 minutes while cutting idle compute costs by 35%.

pacli - Local-First Secrets Management CLI

2025

Published open-source CLI and PyPI package for managing credentials, SSH keys, and API tokens with client-side encryption and zero cloud dependencies.

[The Challenge]Developers frequently leak plain-text credentials and API keys in shell histories and environment files without portable, encrypted storage.
[The Architecture]Built and published an encrypted CLI on PyPI with AES encryption, master password protection, automated Bandit security scans, and GitHub Actions CI/CD releases.
[Quantifiable Impact]Active PyPI package (pip install pacli-tool) with automated security auditing and cross-platform release automation.
