Selected work

The thinking, made tangible.

A few examples of how I turn manual workflows and scattered data into useful software.

All six projects
Invoice Intake workflow from receiving and checks to human review and accounting

Personal demo · Fictional data

Invoices checked before approval.

Invoice checks, human review, and a recorded decision before a simulated accounting export.

The problem & my approach

The problemRetyping invoice details and chasing approvals makes errors and duplicates harder to spot.

The design decisionShow the source document beside the extracted details, flag issues, and require a person’s decision. Duplicates cannot be approved.

Hermes content workflow with review and human approval

Personal workflow · Human approval

AI drafts. The creator decides.

Hermes connects script drafting, a second review, and a human choice through Telegram.

The problem & my approach

The problemContent production repeats the same handoffs between choosing a source, drafting, reviewing, and preparing production.

The design decisionAutomate the handoffs while keeping story selection, script choice, and publishing approval with the creator.

A personal content workflow, not a paid client case study.

Live personal product

Scattered listings. One search.

IsleScout brings property data from multiple sources into a searchable directory across five Greek islands.

The problem & my approach

The problemListings from different sources arrive in different formats, with duplicate records and inconsistent details.

The design decisionNormalize the records, handle duplicates, and give the website and API one consistent search path.

A self-initiated product. Commercial results are unmeasured.

Approach

Understand first. Build with purpose.

AI helps me build faster. Listening, judgment, and professional care guide what I build.

01

Find the real problem.

Understand the people and the workflow. Establish where time, manual effort, errors, and delays add up.

02

Test something concrete.

Start with a focused proof of concept. Try it with the people who will use it before committing to a larger build.

03

Make it dependable.

Agree what success looks like, check what improved, and plan for a clear handoff and ongoing maintenance.

About Luis

Product experience. Hands-on delivery.

I’m a Senior Product Manager who also builds software. I work from the first conversation about a problem through to designing, delivering, and maintaining the solution.

Building software has become easier. The harder part is understanding what needs fixing and whether what we build actually helps.
