Infrastructure Architect · Cloud Engineer · Security Specialist — building resilient, secure, and scalable enterprise environments.
I'm Bayu Aditya, an ICT Infrastructure & Security Specialist with more than 15 years of professional experience spanning network engineering, system administration, IT service management, cloud computing, and cyber security.
My career has been built on one principle: infrastructure should be invisible to end users — always available, always secure, always fast. I've designed and managed enterprise-grade environments for organizations of all sizes, from SMEs to large government-adjacent agencies, ensuring uptime, resilience, and compliance at every layer of the stack.
Beyond the technical work, I bring a service management mindset — bridging the gap between IT teams and business stakeholders through ITIL-aligned processes, structured change management, and clear incident response frameworks. Whether I'm deploying a Kubernetes cluster, hardening a network perimeter, or migrating endpoints to Intune, I approach every task with precision and ownership.
I'm also passionate about knowledge sharing — running a YouTube channel on Hyper-V, writing technical blog posts, and mentoring the next generation of IT engineers.
Led organization-wide standardization of IT infrastructure — unified naming conventions, OS baseline policies, patch management workflows, and documentation across 100+ endpoints and servers.
Designed and deployed scalable server and storage infrastructure — RAID configuration, SAN/NAS setup, backup strategy, and performance tuning for high-availability business workloads.
Configured and hardened enterprise network devices — VLANs, ACLs, routing protocols, firewall rulesets, and VPN tunnels. Implemented network monitoring with real-time alerting.
Migrated fleet of corporate endpoints to Microsoft Intune — enrollment automation, compliance policies, app deployment, and conditional access integration with Azure AD for Zero Trust posture.
Deployed and managed Windows Server Hyper-V environments — host and guest configuration, virtual switch design, VM provisioning, resource allocation, and nested virtualization labs for testing and training.
Built and administered a VMware vSphere environment for production workloads — ESXi host deployment, vCenter management, HA/DRS clustering, resource pools, and VM lifecycle automation for high-availability infrastructure.
Outside of professional work, I run and maintain collabstech.com — a technology blog dedicated to sharing practical insights on IT infrastructure, cloud computing, security, and emerging tech. I also maintain the CollabsTech YouTube channel, publishing hands-on tutorials and walkthroughs on infrastructure and virtualization topics. A personal space for knowledge sharing with the broader IT community.
