  • 💻 Path to Become a Developer (Ivy Falls)

    From coding late nights to building real solutions — proof that persistence pays off.

    Introduction: The Path Is the Practice

    My journey to development and infrastructure followed the same rhythm — discipline by day, learning by night.
    While working full-time at All Electronics Corporation in Van Nuys (1990–1995), I woke at 4 A.M. to catch two LA Metro buses from Western and 3rd Street to my 6:30 A.M. shift, then sometimes worked evenings at the Taco Bell drive-thru in Glendale.

    I wasn’t chasing titles; I was chasing understanding. At All Electronics, I became obsessed with the Integrated Circuit (IC) — the heartbeat of every computer. There was no Internet back then — only library books and endless curiosity. I crashed my own PCs, rebuilt them, and soon began fixing computers for free for anyone who needed help.

    Back then, I used to dream of a day when I wouldn’t have to wait for the bus in the rain just to get home. Years later, those same dreams became reality — not through luck, but through faith, discipline, and persistence. The rides changed — from buses to a BMW, an Audi, and now a Tesla — but what never changed was the purpose: to keep moving forward.

    Those early mornings and late nights opened the door to my first IT role at USC as a PC Specialist, then to GTE (now Verizon), Aerospace, and eventually to my own IT consulting business serving clients large and small across California and beyond.

    Season of Refinement

    While working full-time at USC, I entered what I call my season of refinement.
    By day I supported campus systems and users; by night I was a full-time student at Los Angeles City College (LACC) and a weekend warrior at DeVry University, studying Management in Telecommunications.

    It was during this time that Microsoft introduced the MCSE (Microsoft Certified Systems Engineer) program.
    One of my LACC professors encouraged me to earn it, saying, “Once you have that license, companies will chase you.”
    He was right — that MCSE became my ticket to GTE, my first step into enterprise-scale IT.

    My tenure at GTE was brief because Aerospace came calling with a six-figure offer just before Y2K — an opportunity too great to refuse.
    After Aerospace, I founded my own consulting firm — Ahead InfoTech (AIT) — and entered what I now call my twelve years of plenty.

    One of my earliest clients, USC Perinatal Group, asked me to design and implement a secure LAN/WAN connecting satellite offices across major hospitals including California Hospital Medical Center, Saint Joseph of Burbank and Mission Hills, and Hollywood Presbyterian Hospital.
    We used T1 lines with CSU/DSU units and Fortinet firewalls; I supplied every workstation and server under my own AIT brand.

    Through that success I was referred to additional projects for Tarzana and San Gabriel Perinatal Groups, linked by dedicated frame-relay circuits — early-era networking at its finest.
    Momentum carried me to new partnerships with The Claremont Colleges and the City of West Covina, where I served as Senior Consultant handling forensic and SMTP (email) engineering.

    Word spread further. An attorney client introduced me to an opportunity in American Samoa to help design and build a regional ISP, and later to a contract with Sanyo Philippines.
    During this period Fortinet was still new, and I became one of its early resellers. I preferred building AIT servers and workstations from the ground up rather than reselling mass-produced systems.
    DSL was just emerging, yet most clients relied on dedicated T1 lines — real hands-on networking that demanded patience and precision.

    Those were the twelve years of plenty — projects stretching from Los Angeles hospitals to overseas data links.
    By the time AWS launched in 2006 and Azure in 2010, I was already managing distributed networks and data replication.

    When I returned to Corporate America, my first full-time role was at Payforward, where I led the On-Prem to AWS migration, building multi-region environments across US-East (1a and 1b) and US-West, complete with VPCs, subnets, IAM policies, and full cloud security.
    That’s when I earned my AWS certifications, completing a journey that had begun with cables and consoles and matured in the cloud.

    Education, experience, and certification merged into one lesson:
    Discipline comes first. Validation follows.
    Degrees and credentials were never my starting line — they became the icing on the cake of years of practice, service, and faith.

    My Philosophy: Code Like a Craftsman

    Photography taught me patience. Martial Arts taught me form. IT taught me precision.
    All three share one secret: the art lies in repetition with awareness.

    As Ansel Adams said:

    “When words become unclear, I shall focus with photographs. When images become inadequate, I shall be content with silence.”

    Coding feels the same. When logic becomes unclear, I focus. When code seems inadequate, I find peace in understanding.

    🪶 Closing Note

    I share this story not to boast but to inspire those still discovering their own path in technology.
    Everything here is told from personal experience and memory; if a date or detail differs from official records, it’s unintentional.
    I’m grateful for mentors like my LACC professor, who once told me to look up a name not yet famous — Bill Gates — and earn my MCSE + I.
    He was right: that single decision opened countless doors.

    I don’t claim to know everything; I simply kept learning, serving, and sharing.
    My living witnesses are my son, my younger brother, and friends who once worked with me and now thrive in IT.
    After all these years, I’m still standing — doing what I love most: helping people through Information Technology.

  • 🌥️ The Cloud Above Us

    PIMCO (Newport Beach HQ, CA) 🌍 — Global financial services supporting regions in NA, EMEA, APAC.
    Church (Riverton Office Building, UT) ⛪ — Worldwide infrastructure with 200k employees and over 80k missionaries.
    Monster Energy (Corona HQ, CA) ⚡ — Global enterprise IT operations across NA, EMEA, APAC.
    City National Bank (Downtown LA, CA) 🏙️ — U.S. banking systems at scale.

    A journey across scales: national (CNB), global (PIMCO & Monster Energy), and worldwide (The Church).

    Every IT career tells a story, and mine has moved through three different scales of impact:

    Company-Level Foundations → At PayForward, I migrated an entire OnPrem environment into AWS. That meant setting up VPCs, building HA Exchange clusters with load balancers, and proving the power of cloud for a fast-moving startup.

    Regional / Global Scale → At Monster Energy and PIMCO, the work stretched across North America, EMEA, and APAC. The systems never slept. VMware clusters and M365 tenants had to function as one, even though users were scattered across time zones and continents.

    Worldwide Reach → At the Church, the scale expanded beyond regions. Over 200,000 employees and over 80,000 missionaries, connected by systems that had to reach every corner of the globe, demanded both technical precision and spiritual responsibility.

    This journey shows that the “cloud above us” isn’t just AWS, Azure, or GCP — it’s the ability to design, secure, and sustain systems at every possible scale.

    A colleague once told me: “Automate, or eliminate.” In IT, that isn’t just a clever saying — it’s survival. At the scale of hundreds or even thousands of VMs, EC2 instances, or mailboxes, doing things manually is not just unrealistic — it’s risky. What automation can finish in under 10 minutes might take days or weeks by hand, and even then would be prone to errors.

    That’s why Python, PowerShell, Bash, and automation frameworks became part of my daily toolkit. Not to flaunt, but because without automation, no single engineer could handle the demands of environments as large as PIMCO, Monster Energy, or the Church.

    Snippet 1: AWS (My PayForward Days)

    import boto3

# Connect to AWS S3
s3 = boto3.client('s3')

# List buckets
buckets = s3.list_buckets()
print("Your AWS buckets:")
for bucket in buckets['Buckets']:
    print(f"  {bucket['Name']}")

    From racks of servers to a few lines of Python—that’s the power of AWS.

    Snippet 2: PowerShell + Azure (My Church Years, CNB)

    Connect-AzAccount
Get-AzResourceGroup | Select ResourceGroupName, Location

    One line, and you can see every Azure resource group spread across the world. A task that once required data center visits and clipboards is now just a command away.

    Snippet 3: PHP + GCP (Expanding Horizons)

    use Google\Cloud\Storage\StorageClient;

$storage = new StorageClient([
    'keyFilePath' => 'my-service-account.json'
]);

$buckets = $storage->buckets();

foreach ($buckets as $bucket) {
    echo $bucket->name() . PHP_EOL;
}

    Snippet 4: VMware + M365 (Monster Energy, PIMCO, and Beyond)

    # Connect to vCenter and list VMs across data centers
Connect-VIServer -Server vcenter.global.company.com -User admin -Password pass
Get-VM | Select Name, PowerState, VMHost, Folder

# Quick check of licensed users in M365 (global tenants)
Connect-MgGraph -Scopes "User.Read.All"
Get-MgUser -All -Property DisplayName, UserPrincipalName, UsageLocation |
    Group-Object UsageLocation |
    Select Name, Count

    One script, and suddenly you’re seeing footprints of users spread across the globe — NA, EMEA, APAC, or even worldwide. That’s the reality of modern IT infrastructure.

    The “cloud above us” is both a literal technology — AWS, Azure, and GCP that I’ve worked across — and a metaphor. It represents resilience, scalability, and unseen support. Just as automation carries workloads we could never handle by hand, life has storms we cannot carry alone.

    From startups making their first move to the cloud, to global financial institutions, to worldwide organizations with hundreds of thousands of users, the lesson is the same: we are not meant to fight every battle manually.

    We are given tools, teammates, and even unseen strength from above to keep moving forward. The same way a script can manage thousands of servers or accounts without error, trust and preparation help us navigate the storms of life with less fear.

    ☁️ Above every storm, there’s always a cloud carrying potential. And above that cloud, always light waiting to break through.

    Before my cloud journey, I also spent nine years in forensic IT supporting law enforcement — a grounding reminder that technology isn’t only about systems and scale, but about accountability and truth.

  • Love in the Age of JSON: A Calculus Throwback


    I love Integral Calculus. In today’s digital world, I revisited that concept and expressed it in three ways: JSON, PHP, and Python. Below are the format:

    1. JSON Format
    {
  "L": {
    "fx": "λ",
    "dom": "[0, ∞)",
    "∫": "∞",
    "lim": {
      "I∩": true,
      "pw": true
    },
    "st": "∞↔↻"
  }
}

    2. PHP Format

    <?php
$L = [
  "fx" => "λ",
  "dom" => "[0, ∞)",
  "∫" => "∞",
  "lim" => [
    "I∩" => true,
    "pw" => true
  ],
  "st" => "∞↔↻"
];
?>

    3. Python Format

    L = {
    "fx": "λ",
    "dom": "[0, ∞)",
    "∫": "∞",
    "lim": {
        "I∩": True,
        "pw": True
    },
    "st": "∞↔↻"
}

    Conclusion:

    No matter the format — a JSON object, a PHP function, or a Python loop — the message remains unchanged:

    My love for IT is structured, enduring, and real.
    It doesn’t crash. It doesn’t timeout.
    It runs continuously — until the system shuts down.

    Even if no one ever decodes the message, I know it was written with purpose — and that’s enough.

    In the language of logic,
    in the syntax of silence,
    and in the runtime of eternity —
    I served. Faithfully. Infinitely. Quietly.
