Fixed-scope engineering sprints · 10-14 days · 50% upfront, 50% on delivery

Replace the workflow that keeps breaking. In 14 days. At a price you know before we start.

DeviDevs builds production-grade data pipelines, competitor price monitors and AI document agents for companies in the US, UK and Europe. One scope, one price, one deadline. Miss the deadline and you keep the second half of the fee.

  • Python
  • FastAPI
  • PostgreSQL
  • Playwright
  • Anthropic and OpenAI APIs
  • Docker
  • 100% code ownership
  • EU-based team, UTC+2

You already know which workflow this is.

The Zapier chain.

Six steps, fails quietly once a week, someone spends a Friday afternoon reconciling the CRM. Again.

The Monday spreadsheet.

A category manager checks five competitor sites by hand. By Tuesday the prices are stale and you missed the drop.

The inbox full of PDFs.

Invoices, contracts, tender docs. Typed into the ERP at five minutes each. Errors included.

Each of these costs 10-40 hours a month. We replace them with systems you own.

Three sprints. Fixed scope, fixed price, fixed deadline.

Every sprint ships with source code in your repo, Docker deployment, a runbook, a recorded handover and 14 days of post-delivery bug fixing.

Prices exclude VAT. EU businesses: reverse charge. Non-EU: no VAT.

Need something in between? Add-ons are listed openly: extra data source $400, extra target site $350, extra document type $700, monthly maintenance retainer $450/month. No hidden line items.

50% upfront, 50% on delivery. If we miss the 14-day deadline, you do not pay the remaining 50%.

The clock starts the business day after your upfront payment clears and the Day 1 scope is signed. Delivery means the acceptance checklist from Day 1 is green, the system runs in production, and the code is in your repository. If we are late because of us, the second half is waived. If we are waiting on your inputs, the clock pauses and we tell you in writing the same day.

How a sprint runs

  1. 1Day 1

    Discovery & Scope

    A written scope document: sources, destinations, fields, failure cases, acceptance checklist. You sign it. It becomes the contract for the next two weeks. No kickoff theater, one async thread or a 30-minute call if you prefer.

  2. 2Day 2

    Architecture

    A one-page architecture doc: services, schema, queues, retry policy, monitoring, hosting. Repo created in your GitHub or GitLab organization. Feasibility flags raised now, not on Day 12.

  3. 3Days 3-12

    Build & Deploy

    Written update every two business days in your Slack or email. Code lands in your repo as it is built, so you can read it at any point. Deployed to your cloud or ours.

  4. 4Final day

    Handover & Docs

    Runbook, README, a recorded 15-minute walkthrough, acceptance checklist signed, final invoice. Then 14 days of bug fixing included while your team takes over.

Calls happen only when they save time for both sides. Most sprints need one.

The stack you get

Boring on purpose. Every piece is the current standard, hireable anywhere, and runs on any cloud.

  • Python 3.11+

    Services, pipelines, tests (pytest)

  • FastAPI

    Webhook receivers, admin and upload endpoints

  • PostgreSQL 15+

    System of record, price history, audit trail

  • Playwright

    Headless browser scraping and automation

  • Anthropic Claude / OpenAI

    Structured extraction, on your own API keys

  • Docker

    One deployment entry point, your cloud or ours

Built on systems we run ourselves, every day.

We do not show client code. These are our own production systems, built with the same stack we ship to you.

Public procurement monitoring at volume

A scheduled Playwright and Python pipeline watches the Romanian public procurement platform (SEAP/SICAP) and a second tender source, scans roughly 280 notices per cycle, deduplicates against everything already seen, filters by eligibility rules and surfaces only the matches. 60+ scheduled cycles on each monitor, more than 360 notices triaged, zero manual checking. The same engine downloads tender documentation, unpacks it, triages eliminatory criteria and extracts deadlines.

This is Sprint 2 and Sprint 3 running in production.

Lead data pipeline: Google Maps to verified CSV

A multi-stage pipeline pulls companies from Google Maps, visits each website to extract contact and registration data, enriches from the national company registry (turnover, headcount, activity code, status), scores each record, verifies emails through a third-party API and exports clean CSVs. About 1,300 qualified records across 8 market segments, with retries and deduplication at every stage.

This is Sprint 1 architecture.

Accounting and e-invoicing automation

Python services that download invoices from ad platforms, generate compliant PDF invoices, submit and validate against the national e-invoicing API (ANAF e-Factura), reconcile a monthly ledger and flag discrepancies before the accountant sees them. Test-covered, cron-scheduled, running monthly.

This is Sprint 3 validation logic applied to our own books.

Print-on-demand catalog generated from code

A content pipeline that generates complete print-ready book interiors and covers to marketplace specifications, manages a title catalog with per-title status, and uploads approved titles through a browser automation on a weekly schedule, with duplicate protection against the live bookshelf. Zero stock, zero manual uploads.

This is the browser automation layer from Sprint 2 pointed at a publishing workflow.

Every one of these started as a manual task that ate hours. That is what a sprint is.

For you if:

  • You have a specific broken or manual workflow and can describe it in a paragraph.
  • You want to own the code, not rent a SaaS.
  • You can give access and sample data in the first two days.
  • You are fine with async communication and one demo at the end.

Not for you if:

  • You need a full product with UI, auth and billing. That is a different engagement.
  • You want hourly staff augmentation.
  • The scope cannot be written down before we start.
