TexargIs gender inequality justified by God, or has it been misinterpreted for millennia?
Drag to spin · double-click to fly
Born in Buenos Aires, building in Austin, Seoul this fall. CS at UT Austin, previously an SWE intern at PayPal, growing Texas Blockchain. I build software that takes tedious work off people's hands, and write essays about everything else.
Built
Patients book, move and cancel their own appointments by texting the clinic's WhatsApp in plain Spanish. No menus, no phone tree.
Live at Centro Médico CEPEM in Buenos Aires and in clinics across seven countries. It never diagnoses or recommends medication. Writing to a real clinic's calendar is the part that took a summer.
PayPal
Rebuilt the front end of PayPal's instant commerce links, the buttons a merchant uses to sell something from a photo, a price and a link.
Owned it from low-level design through a staged production ramp. Those buttons move more than a million dollars a month.
Texarg
Custom automation for local businesses: appointment reminders, lead routing, document processing, billing. I map where a business is losing hours, then build the thing that stops it. Not templates.
Writing
Mostly religion and political philosophy. Class essays I liked enough to publish.
Religious Interpretations of Gender Inequality
01 Aug 2026
Idolatry, Truth, and Religious Boundaries
30 Jul 2026
Could there be a logical reasoning for the greater reconciliation between the Abrahamic practitioners, or even all religions?
Abundance of Freedom, Poverty of Property
28 Jul 2026
The State of Nature offers immense abundance in freedom. However, this freedom is worthless as it doesn't allow prosperity and property to gain value.
Now
Updated 13 August 2026
- Packing for Seoul, studying abroad there for the fall.
- Building Klini, and rebuilding this site while I'm at it.
- Writing SWE at PayPal during the day, growing Texas Blockchain at UT the rest of it.
- Deep in SVG animation. The globe above is eight path elements and about 6 KB of maths, no images.
- One line about what you're reading or arguing with right now. This is the slot people actually read to decide whether you're interesting, make it specific.
Elsewhere
Backstage, not part of the site
Why it's shaped like this
One dotted line left on the whole page, the last Now item. Everything else is real, including the Klini wordmark, which is Lucas's own.
On the Klini row
I cut the pricing, the plan tiers and the feature list. This is a personal site, not a sales page. The job of that row is to make someone think "that's a real product, built by someone who understands the problem," and then click through. Three facts do that: that patients manage their own appointments in plain language, that it refuses to practise medicine, and that it's live at CEPEM and selling in seven countries. Everything else belongs on Klini's own site.
The demo ends on a changed state, not a promise. It used to close on a handoff to reception, because that's what the product did. Now that Klini books, moves and cancels appointments itself, the last beat is the appointment actually moving, TURNO REPROGRAMADO. That's a categorically different claim, and the demo should carry it.
"Never diagnoses, never recommends medication" stays. It isn't a caveat, it's the most credible sentence available, the line that tells a clinic director you've thought about liability. It matters more now, not less: a bot that can write to the calendar is a bot with real reach, so the fence around it is worth naming.
The demo is in Spanish because the customers are. Translating it for an English-reading visitor would make it a mock-up; leaving it in Spanish makes it a screenshot of the real thing, and the times and the closing chip read clearly even if you don't speak it.
One thing the essays changed
Your public writing is theology and political philosophy, not tech. Genesis and 1 Timothy on gender, idolatry across the Abrahamic texts, Locke on the state of nature. I'd been building this as a builder's site with a writing section bolted on, but a CS student at UT who ships automation software and also publishes essays arguing with Paul is a far more specific person than "developer with a blog."
So I gave the section a subhead that says what the essays actually are, rather than letting a visitor assume they're posts about React. The tension is the interesting part; hiding it would be the mistake. If you'd rather the site lead on the writing instead of the building, that's a real option, say so and I'll reorder.
Five sections, no nav
Built, Writing, Now, Elsewhere. A menu would be four links to things already visible in one scroll. On a phone it'd just be a hamburger hiding nothing.
Prose, not cards
Each project is a name, a status, and two sentences. Cards with thumbnails are what a junior portfolio looks like; sentences are what benji.org looks like.
One drawn stroke, four jobs
The flight trail, the wordmark underline, each section rule, and the wire down the gutter are all the same pen. Nothing else is decorated.
Now beats About
A dated list of what you're actually doing ages honestly and gives people a reason to come back. An adjective list ("passionate builder") does neither.
Hover has a tap twin
The scratch underline on each project fires on focus and touch, not just hover, and the wire is driven by scroll, which is the one input a phone always has.
No icon row
Socials are a labelled list with your actual handles visible. Icon rows are the single fastest way to make a personal site look like a template.
What's left
- One true line for Now. What you're reading or arguing with this month. Last invented thing on the page.
- Does the site have a job? Internships, clients, or just existing. It reads as "just existing" today, but with Klini selling in seven countries, "clients" is now a plausible answer, and it would change the copy throughout.
- Lead with building or with writing? Built is first. With Klini in it, I'd now say keep it that way. A shipped product beats an essay as an opening move, and the essays are the surprise that makes you memorable once someone's already reading.
- Two live demos in one section, Klini's chat and Texarg's workflow. I think both earn their place because each is the section's content rather than decoration, but if it feels busy, Texarg's is the one to cut.
On the essay list
Three is a thin shelf, and X's articles tab needs a login to enumerate, so I couldn't scrape the full set, only the three you sent. For the real build I'd keep a small essays.json in the repo: title, date, URL. Thirty seconds to add one, no API keys, no rate limits, and the page stays static.
Then
The real thing: Astro on Vercel, this exact markup, essays from that JSON file, and an og:image that renders the globe at the moment of touchdown. About a day once Klini lands.
