More than a developer, less than an agency: one senior consultant who scopes it, prices it, builds it, and hands it over running, with 12+ years of shipped production software behind every decision.

Start where you are
Quoting, scheduling, or job tracking lives in Excel and somebody's head. It worked at five people. It is breaking at fifteen.
Replace the duct tape →A freelancer disappeared, or an AI tool got you 70% of the way. Now you need someone to finish it properly and make it safe to rely on.
Get it finished →The CRM, the accounting tool, and the ops spreadsheet each hold a piece of the truth. People re-type data between them every day.

How the engagement runs
Whichever situation brings you here, the engagement runs the same way: I scope it, I price it, I build it, and I hand it over running. Scoping comes first because it is how I make sure the thing that gets built is the thing your business actually needs.
How the work actually flows, and what deserves software.
From my own plan, at my own estimate. The focused core goes to production first, then stages your team can absorb.
Deployed, monitored, documented. Code in your repository, every account and credential in your name.
Field-service workflow: build vs buy
synthetic example · real memos are redacted before sharing
Options weighed
The tool covers scheduling, dispatch, job notes and photos. It misses the seasonal pricing rule, about 10% of jobs.
An off-the-shelf field-service tool covers about 90% of this workflow for $79 a month. The remaining 10% does not justify a custom build at ten times the cost. Configure the tool, connect it to invoicing, and revisit in a year with real usage data.
Every engagement produces a decision memo: the reasoning behind every major tradeoff, written so you can challenge it. Some engagements end exactly like this page, with advice to spend less. The memo is the deliverable either way.
Work
2021 DMH/DINAC, Paraguay, with WWF Paraguay
A public platform that pulls fire detections from four NASA satellites, matches them against areas people have drawn on a map, and emails only the people whose land is affected.
2022 Reelbox, Australia
A portal that replaced emailing photo proofs for an Australian video archiving business. The business uploads a batch as a ZIP, its customer signs in with an access code to browse and choose favorites up to a set limit, and the chosen photos come back as one numbered, branded archive.
2023 Eric's Yard Care, Canada
A field service portal for a yard care business: visits scheduled, work logged on site with photo evidence, and a history each customer can see for their own property.
Who you’ll work with
Me. That is the point. I'm Ever Barreto, the principal and the person who does the work: the scoping, the architecture, and most of the code. The person you talk to on the first call is the person who ships the system. When a project needs more hands, I bring in collaborators I have shipped with before, and I stay accountable for the result.
I work from Asunción, Paraguay, UTC-3. My working day overlaps almost completely with US Eastern time, and by four to five hours with the UK.
