Case Studies

Real infrastructure problems, practical outcomes.

A look at how I approach cloud cost, VoIP architecture, AI automation, and reliability challenges — problem, approach, impact, and technologies.

Problem: A growing production environment saw cloud spend increase faster than usage, driven by over-provisioned compute, idle resources, and architecture choices that were never revisited after early scaling.
Approach: Conducted a full billing and architecture review, mapped spend to workloads, identified over-provisioned and idle resources, and designed a right-sizing plan with clear priorities.
Impact: Reduced monthly waste through right-sizing and storage cleanup, improved cost visibility, and established a sustainable scaling model. (Exact figures are placeholders pending client approval.)

Problem: A communication provider needed a multi-tenant PBX architecture that could isolate tenants, scale call capacity, and remain maintainable as the number of customers grew.
Approach: Designed tenant isolation, SIP routing, and provisioning patterns on FreeSWITCH and FusionPBX, with attention to call flow clarity, recording, and reporting.
Impact: Delivered a repeatable multi-tenant architecture with predictable routing, cleaner provisioning, and improved operational visibility across tenants.

Problem: A business wanted to move AI from ad-hoc experiments to dependable infrastructure that could run private workflows, keep data in-house, and integrate with existing tools.
Approach: Planned GPU and compute capacity, deployed a private LLM stack, added a vector store for retrieval, and connected automation pipelines to business systems.
Impact: Enabled repeatable, private AI workflows with reduced manual effort and clear integration points, moving AI from experimentation to operational use.

Problem: An Azure environment had grown organically, leaving unclear ownership, inconsistent sizing, and costs that were difficult to explain or predict.
Approach: Assessed resource groups, networking, and managed services; identified inefficiencies; and produced a prioritized plan for cost and reliability improvements.
Impact: Clarified ownership, reduced avoidable spend, and improved reliability posture with a prioritized, low-risk implementation path.

Problem: Accumulated call-flow complexity on a FusionPBX and FreeSWITCH deployment caused routing confusion, inconsistent behavior, and difficult troubleshooting.
Approach: Audited existing dialplans, IVRs, and queues; simplified routing logic; standardized patterns; and improved recording and CDR reporting.
Impact: Delivered more predictable routing, improved call quality, reduced downtime risk, and cleaner reporting for the operations team.

Problem: A critical Linux environment suffered recurring instability with limited monitoring, making failures hard to predict, diagnose, or prevent.
Approach: Stabilized the environment, addressed root causes, and introduced monitoring, backups, and reliability practices to reduce future incidents.
Impact: Restored stability, improved observability, and reduced the likelihood and impact of future incidents through practical reliability measures.
