A studio with a record.
Not a brand with a slogan.
This studio did not begin on the internet. Fifteen years before SOTO⟂DEV, the same operator was delivering technical portfolios at Fortune 100 scale and leading public-sector digital transformation in the United States. The site is new. The discipline is not.
Alvin Soto
Founder · principal engineer
15 years. Real delivery. Documented.
Every engagement listed below is public record — checkable on LinkedIn or referenced in the public works register. Full record available under NDA when the scope warrants it.
The same method, every engagement.
Written scope before code
Every engagement starts with a scope document. What will be built, what will not, how it will be tested, when it will be delivered. Signed before development starts.
Runbook, recovery, changelog — every system
Every system ships with an operator runbook, a recovery procedure, and a change log. The team that inherits the system can operate it on day one.
Technical and executive in parallel
Communication is tuned for both audiences simultaneously. Engineers get architecture decisions. Executives get outcome summaries. Neither gets the other's noise.
Optimized for year three
Every architectural decision is made with the third year in mind — when the original team has turned over, when usage has scaled, when the spec has changed. Not the demo.
The studio behind the principal.
SOTO⟂DEV is a principal-led practice with a vetted network of specialists. Every engagement can draw on the following roles — documented in the continuity plan shared before work begins.
