Tooltician — Carlos Ortega Gonzalez Scoped engagements for ops-heavy teams · EN / ES

Python automation, internal tools, and web technical hygiene — built to survive handoff.

elrincondeebano.com live store · daily orders, 100+ SKUs, 0 outages in 14 months

I help operations-heavy teams replace spreadsheet glue, brittle reporting, and manual review loops with Python systems that are easier to run, inspect, and hand off.

Best fit: reporting pipelines, ETL cleanup, scraping, internal tools, and stabilization work where the workflow already matters. Start with proof, then open a short brief.

I also cover web technical hygiene for live sites: security headers, HTTPS, DNS, forms, and lightweight monitoring — no internal hire needed. View web technical hygiene

What the work replaces

Replace recurring copy-paste and spreadsheet glue with repeatable runs.
Make ETL, scraping, and reporting failures easier to detect before they hurt operations.
Catch invisible technical issues in live sites — broken forms, misconfigured DNS, absent headers — before they quietly cost leads or trust.

Operating notes

Scope: Reporting automation, ETL reliability, scraping, internal data tools, and workflow stabilization.
Delivery: Scoped implementation, direct communication, explicit assumptions, and handoff-ready docs.
Availability: Open to new scoped engagements. Reply within 48 h with a direct fit or no. Free 15-min diagnostic call — you leave with clear scope direction, not a sales pitch.
Location: Santiago, working EN/ES across LATAM and U.S.-friendly hours.

SMBs with a live site and no internal technical team.
Agencies needing external support for recurring low-margin maintenance.
Professionals and consultants where the site generates leads or reputation.

No alarmism. No promises of total security. Just clear technical review, verifiable fixes, and a before/after report.

Proof

Published, Live, and Tested

Packaging, quality systems, and communication style — all verifiable from public repositories and live deployments.

Packaging

Reusable libraries & CLIs

Projects like rutificador, bankrecon, and Monedario show the same packaging instinct across code and content: reliable structure, clear docs, and outputs people can actually use.

Quality

CI, scans & auditability

I bias toward test coverage, code scanning, deterministic outputs, and logs that make incidents easier to understand rather than harder to trace.

Communication

English-first, bilingual delivery

I write public project docs in a way that works for international readers while still supporting Spanish-speaking collaborators and clients.

Delivery

Lightweight systems that hold up

Automation that saves operator time, front ends that improve comprehension, and repositories that show how the work is maintained.

Portfolio Manager

Desktop-first Electron app with local-only persistence, session-secured Fastify backend, deterministic finance math, provider failover, and a deep automated test/quality stack.

About

Fit and Delivery

My approach starts with the workflow, not the code. Before implementation begins, every engagement goes through a scope pass — inputs, outputs, owner, failure modes, and handoff target. What gets built is a system the next person can run, diagnose, and improve without reverse-engineering it.

Explicit tradeoffs documented before decisions are made. Progress visible in GitHub commits, not status updates. Delivery notes written so the next person can run, debug, and extend the system without the original author on a call.

Best fit

Operations-heavy teams with a real reporting, ETL, scraping, or internal-tool bottleneck already affecting work.
Founders and managers who need a scoped build, not a permanent embedded product team.
Teams that value bilingual communication and a written handoff.
Not a fit: open-ended product teams, brand-only marketing sites, or undefined ownership.

What delivery includes

Short discovery to lock scope, constraints, and success criteria before implementation.
Visible progress, documented assumptions, and pragmatic tradeoffs instead of surprise scope creep.
Handoff materials: README, operating notes, setup steps, and the failure points worth watching.

Preferred stack and limits

Python, SQL, Bash, FastAPI, Selenium, BeautifulSoup, Pandas, Astro, and reliability-minded packaging.
GitHub Actions, CodeQL, package publishing, and repo structures built around tests and docs.
Not ideal for open-ended product strategy, full design-system programs, or staff augmentation with undefined ownership.

FAQ

Common questions before we start

What exactly do you do?

Two things: Python automation systems (ETL pipelines, scrapers, internal tools, and reporting workflows) and web technical hygiene for live sites (security headers, HTTPS, DNS, forms, Search Console, and lightweight monitoring). Both are scoped, documented, and built to keep running after handoff.

How much does it cost?

Scoped automation starts from 30 UF (~USD $1,200). An optional stabilization retainer is from 6 UF/month (~USD $240/mo). Web technical hygiene starts at a $69 diagnostic. Every engagement begins with a free 15-minute diagnostic call to confirm fit before any quote.

How does a project start?

With a free 15-minute call to confirm the problem is a fit. If it is, the next step is a short discovery to lock scope, inputs, outputs, owner, and success criteria — agreed in writing before implementation begins.

Do you work in English or Spanish?

Both. Delivery, documentation, and communication are bilingual. The Spanish-language services are calibrated for the Chilean and Latin American market; the English-language services are priced and delivered for US, UK, and European clients.

Where are you based, and do you work remotely?

I'm based in Santiago, Chile, and work remotely with clients worldwide. Engagements run async with visible progress in GitHub commits instead of status meetings.

What happens after the project is delivered?

You get handoff materials — README, operating notes, setup steps, and the failure points worth watching — so the next person can run, debug, and extend the system without me on a call. An optional retainer is available if you want ongoing stabilization.

Is this a one-off build or an ongoing service?

Either. Most work is a scoped, fixed-outcome build. If the system needs continued upkeep, a monthly stabilization retainer is available — but it is optional, not a lock-in.

Can I see real examples of your work?

Yes. Live systems include El Rincón de Ébano (e-commerce) and Monedario (personal finance for Chile), plus published PyPI packages (bankrecon, rutificador) and open-source tools on GitHub. The work section links each one.

Project Brief

Send the workflow, the bottleneck, the current owner, and the outcome you want.

How it works

01
Send a brief or book a call
Describe the workflow, the bottleneck, and what working looks like. A short note is enough — no deck required.
02
Fit response within 48 h
Direct yes or no on fit. If it is close, one clarifying question. No follow-up sequence if it is a no.
03
Scoped proposal on a match
Concrete deliverables, timeline, deposit terms, and handoff plan. No ambiguous retainers or open-ended commitments.

Use the form as the starting point. A short note is enough — cover the workflow, the bottleneck, and what a good result looks like.

Fit: scoped automation, ETL cleanup, scraping, internal tools, or web technical hygiene for a live site with a clear owner. Not fit: open-ended discovery without a concrete workflow or site.

Currently open for new scoped engagements.

Useful in the first note

Current workflow and tools involved.
Main bottleneck, failure, or review risk.
Desired output and who will operate it.
Deadline, cadence, or handoff constraint.
