The face behind your software.
Systems, automations, and digital products designed around the process your company already has — not around what an off-the-shelf tool allows. Fixed-price proposal within 1 business day.
01 — The problem
Software shouldn't feel generic.
Every company has its own way of operating. Off-the-shelf tools force the business to fit the software — and the result is a mask hiding the face of the operation.
Faceless
With a face of its own
Generic
Processes bent to fit the tool
Custom

Generic
Side spreadsheets to cover what’s missing
Custom
One single source of data, no workarounds

What's stuck02 — Work
Projects with a face of their own.
Digital products built by Rost Dev — from the business problem to a solution in production.
Momentos
- Problem
- Photographers had no single place to track work sessions, time of day, and earnings.
- Solution
- An app with work sessions, a real-time day timer, earnings tracking, and AI-generated captions.
- Result
- Partner photographers report spending about 30% less time organizing their schedule and daily billing.
Order management
- Problem
- A regional beverage distributor tracked orders across loose spreadsheets and WhatsApp groups, with no clear view of what had shipped or what stock needed restocking.
- Solution
- A single dashboard for orders, stock, and customers, with status-based workflows and automatic alerts when an item nears its minimum threshold.
- Result
- About 40% less time closing out orders at day's end, with stock always matching what's on the shelf.
Logistics automation
- Problem
- A mid-size trucking company relied on phone calls and manual hand-offs between drivers, the warehouse, and support at every stage of a delivery.
- Solution
- Automated the shipping workflow with automatic notifications between teams and real-time tracking for the end customer.
- Result
- About 25% fewer status-check calls and a faster response time to delays.
Casa Verde Ateliê
- Problem
- Sales only through WhatsApp and Instagram: with no catalog, every order turned into a manual negotiation, and customers sometimes waited days for a reply.
- Solution
- An online store with a catalog, per-variant stock, and its own checkout, with no marketplace fees.
- Result
- About 35% of orders now close on their own through the site, with no WhatsApp back-and-forth needed.
Trilha Urbana
- Problem
- An outdated stock spreadsheet led to selling products that were already out of stock.
- Solution
- An e-commerce store with stock synced to the physical shop and product filters by category and trail.
- Result
- Eliminated out-of-stock sales, and trail-based filtering lifted catalog conversion by about 20%.
