Custom business software · New York

Software built around the way your business actually works.

I learn the operation, then build the system—from reservation to closeout, estimate to final payment. One useful product, made for your team.

Custom, not off-the-shelf

Built by Donald Lena

The best software starts with the messy part of the business.

Text threads, spreadsheets, missed follow-ups, duplicate entry, and information living in one person’s head are not just annoyances. They are the product brief.

01

Learn the real workflow

I map what happens now, who owns each step, where context gets lost, and what should stay human.

02

Build one connected system

The app follows your language and sequence—customers, jobs, reservations, staff, money, and reporting in one place.

03

Launch it with the people using it

Mobile-first screens, role-aware access, practical training, and improvements based on the floor—not a handoff and goodbye.

Flagship build · Le Yard OS

Building the restaurant now

The restaurant and its operating system are coming to life together.

Le Yard is a French-leaning neighborhood restaurant now being built at 858 9th Avenue in Manhattan. I am building the real business and the software meant to run it at the same time.

Private hospitality software

Prestige Lounge · Brooklyn

Custom operating software for a Brooklyn hospitality venue. The client workspace stays private; the product follows the venue rather than forcing the venue into a template.

Private client system

Interface mockups illustrate the type of workflow built for each business; private client records and live financial data are not shown.

Start with the broken workflow

Tell me what your team is holding together by text, spreadsheet, and memory.

I will look at how the business works now, tell you what should become software, and be honest about what should not.
