LainDS

You talk to the engineer who designs your system, not to a salesperson.

We build custom software for organizations where a specific process is the differentiator — and no off-the-shelf product covers it.

What we've built:

Central cashier system for a national university (UNJFSC): real-time receipt validation against RENIEC, Peru's national identity registry. It closed the door on forged receipts. Java 21, Spring Boot, Angular 18, SQL Server, microservices, multi-branch, thousands of transactions per month.

Enrollment system for a 50,000-member club (Club de Regatas Lima): a virtual access queue that holds the enrollment-day surge without the system going down, plus SAP Business One integration for automated invoicing. React, NestJS, MongoDB, AWS.

Cloud inventory platform for a furniture retailer: AWS microservices, real-time stock tracking, ERP integration. Cut stock discrepancies 32% and financial reporting time 52%.

Sectors: higher education, government, clubs and membership organizations.

How we work:

Senior engineering. The person who designs your system writes it.- Your code is yours. No lock-in. The system is an asset you own and can audit.- We tell you when you shouldn't hire us. If an off-the-shelf product covers your process, buy it.

We don't quote without discovery. Scope first, then numbers.
