What we do
One thing, done properly.
We’re genuinely deep in one discipline: custom web applications on Django. Everything else on this page either supports that build or extends it once it’s live.
Our core service
Custom web applications, built on Django
The system your team logs into every morning: quoting tools, client portals, inventory and billing, admin dashboards, multi-tenant SaaS. We model how you actually work instead of forcing you into a template, then back it with tests, migrations and a deployment you can trust.

- REST APIs for your other tools
- Background jobs & scheduled reports
- Payments, invoicing & PDF exports
- Responsive UI your staff won’t fight
- Data migration from spreadsheets

Automation, AI & data
Scrapers that gather what you need, WhatsApp bots that answer for you, an LLM feature living inside your app, a dashboard that finally shows the numbers. Small builds, outsized payoff.

Rescue & maintenance
Inherited a codebase nobody wants to open? We audit it, document it, get the tests green and keep it patched. And if a rebuild is honestly cheaper, we’ll tell you that instead.

Add-on modules
Extras you can bolt onto any build, or hire us for on their own.
These pair naturally with a web app, but plenty of clients bring us just one of them. Every price is a starting point; you get a fixed quote after we scope it.
AI & LLM features
From $600
Assistants, document Q&A, smart search and drafting, wired into your own data, not a generic chatbot.
Web scraping & data
From $450
Scheduled extraction, price and stock monitoring, and clean structured exports you can build on.
Analytics dashboards
From $500
Your KPIs in one place: live charts, filters and reports people will actually open on a Monday.
Bots & automations
From $350
WhatsApp and Telegram bots, scheduled jobs, and alerts that fire on real events in your data.
Why Pytronic Labs
Engineers who’ve had to fix the hardware too.
Pytronic, C.A. has spent over a decade repairing the machines other people’s software runs on. That habit of diagnosing before replacing, and measuring before claiming, is how we write code.
You get the repository on day one
Your GitHub organisation, your commits, your infrastructure accounts. We work inside your house, not ours. If you ever want to bring the work in-house or hand it to another team, there is nothing to unlock, migrate or renegotiate. That freedom is the whole idea.
MIT / your licenceNo lock-inDocumented handover
Weekly builds, not monthly promises
Every Friday there’s a URL you can click and a short note on what moved. Scope drifts get caught in week two, not week nine.
Priced in ranges, quoted as fixed
You see a starting price before you talk to us. After scoping you get one fixed number and one date. No hourly meters running quietly in the background.
You talk to the person building it
No account manager relaying requirements. The engineer writing your migrations is on the call, which is why scoping calls are short and accurate.
Latin American rates, senior output
We’re based in Mérida, Venezuela and bill in USD. A budget that buys three weeks of a European agency’s time buys a finished, deployed application here, and without the quality trade-off that sentence usually implies. Our timezone (GMT-4) overlaps a full working day with North America and the mornings of most of Europe.

How we work
Five steps. No surprises in the middle.
The riskiest moment in a software project is the silence between kickoff and delivery. We remove it by making the work visible every single week.
STEP 01
Scoping call
Forty-five minutes, free, no deck. You describe the problem; we ask the awkward questions that surface the real requirements.
STEP 02
Proposal & fixed quote
A written scope, a data model sketch, one price and one date. If we think your idea is cheaper to solve another way, we say so here.
STEP 03
Design & architecture
Screens and schema before code. You approve the flows, we lock the data model, the one part that’s genuinely expensive to change later.
STEP 04
Build in weekly slices
A live staging URL from week two onward. Every Friday: what shipped, what’s next, what needs a decision from you.
STEP 05
Launch & handover
Deployment, monitoring, a walkthrough recording and written docs. Thirty days of warranty, then an optional care plan.

Products we designed, built and still run.
We started by building for ourselves. Every platform below is live, maintained by us, and carries real traffic. That’s a more honest portfolio than a folder of mockups.

Pricing
Starting points, published.
Real ranges so you can tell in thirty seconds whether we’re a fit. After the scoping call you get one fixed price for the agreed scope. These numbers are where projects begin, not averages.

Questions
The things clients ask first.
Because it is boring in the ways that matter. Django gives you authentication, an admin interface, database migrations, security defaults and a twenty-year track record out of the box, so your budget goes into your actual business logic instead of rebuilding login screens. It’s also easy for the next developer to pick up, which protects you more than any contract clause does.
We are on GMT-4, which is the same working day as the US East Coast and a solid morning overlap with Western Europe. Communication happens in English or Spanish over your preferred channel: email, WhatsApp, Slack or scheduled calls. Invoicing is in USD. You get a weekly written update whether or not we meet, so the relationship never depends on catching each other live.
That’s the normal case, and it’s what the scoping call is for. Bring the problem, not the specification: the spreadsheet everyone hates, the process that keeps breaking, the report that takes a day to assemble. We’ll tell you what the smallest useful version looks like and roughly what it costs, before you’ve committed to anything.
A written agreement with a fixed price and a delivery date. Typically 40% to start, 30% at the mid-project milestone and 30% on launch. Larger platform builds are split across monthly milestones instead. Intellectual property transfers to you as payments clear, and the repository is in your account throughout.
Thirty days of warranty on anything that doesn’t behave as specified, at no charge and no argument. After that you can take the project fully in-house, call us per change, or put it on a monthly care plan covering hosting supervision, security updates, backups and a set allowance of changes. Most clients start on a care plan and taper off.
Yes, with one condition: we start with a paid audit, usually a few days, before agreeing to anything long term. Inheriting a codebase blind is how both sides end up unhappy. You keep the audit document regardless of whether you continue with us.
