Automation engineer · Weekend consulting

Repetitive work, engineered out.

I turn time-consuming business tasks into reliable automated processes—using the tools you already have, or building the right software when you need something better.

Employed full-time Monday–Friday. Accepting select client projects on weekends.

Example invoice automation: a new file is received, validated and routed, then the record is updated.

Automation workbench

Take a process apart. Put it back together without the busywork.

Pick a familiar task to see how I think: remove the repeated touches, keep the judgment calls, and make the result visible.

What I automate

From recurring task to reliable system.

The technology is secondary. The goal is to remove friction, reduce errors, and give your team time back.

01

Process automation

Turn repetitive, manual work into dependable workflows that move information, trigger actions, and keep teams in sync.

  • Approvals
  • Notifications
  • Document routing
  • Data entry
02

Custom web apps

Build focused software that replaces scattered spreadsheets, inbox requests, and fragile handoffs with one clear workflow.

  • Internal tools
  • Operations apps
  • Admin portals
  • Dashboards
03

Data operations

Clean, transform, connect, and report on business data—from an Excel workbook to a cloud-backed application.

  • VBA workflows
  • Data processing
  • API integrations
  • Reporting

How I work

Practical automation starts with the process—not the platform.

I start by understanding where the work gets stuck. Then I choose the simplest dependable combination of business tools, cloud services, web applications, and custom code to remove that friction.

Bring me your repetitive task
  1. 01

    Find the friction

    Map the task, handoffs, exceptions, and the real cost of doing it manually.

  2. 02

    Fit the right tools

    Use what already works in your business and introduce new technology only where it adds value.

  3. 03

    Build for real life

    Deliver a maintainable solution with clear status, error handling, and room to grow.

A flexible toolkit

Use the stack that fits the work.

From a focused Excel macro to a custom web application, I work across the layers needed to finish the job.

About Elier

I bridge business operations and software engineering.

I’m an automation engineer who enjoys taking a task that happens over and over—and making it happen accurately, consistently, and with far less effort.

My experience spans business-process automation, programming, custom web application development, Excel and VBA data workflows, Power Platform, integrations, and cloud technologies. That range lets me focus on the outcome instead of forcing every problem into one tool.

Weekend project availability

What should your business stop doing manually?

Tell me about the repetitive task, slow handoff, or disconnected process you want to improve. I’m available for select client projects on weekends alongside my full-time weekday role.

Saturday Build + delivery
Sunday Review + handoff
Small, focused engagements work best.

No hard sell. Start with the process and we’ll see if there’s a fit.
