# Software development in San Diego, CA > Biotechnology, defence contracting and wireless telecommunications, three industries with long development cycles and no tolerance for an unexplainable result. If you're in one of them, a model that informs a decision has to show what it read, and evaluation has to produce a number someone can defend. Canonical: https://www.techfabric.com/custom-software-development-san-diego Serving: San Diego, La Jolla, Carlsbad, Chula Vista, Escondido, Oceanside Headquarters: 1530 E Williams Field Rd, Ste 201, Gilbert, AZ 85295. No office in San Diego. --- ## Why San Diego work is our work When a project is stuck waiting for engineers, the shortcut is a vendor whose delivery team you never meet. Our senior engineers work inside your team instead, building platforms and pipelines where provenance is part of the product and a replay gives the same number twice. The labs of Torrey Pines and Sorrento Valley set that bar in San Diego, and a Hillcrest hospital or a defence supplier's back office wants the same exactness. ## Dynamics 365 consultants in San Diego Biotech suppliers in Sorrento Valley, Navy subcontractors around San Diego Bay and North County's craft and consumer brands run Dynamics 365 Business Central for lot tracking, government contract costing and distribution. We implement it with Dynamics 365 CRM and build the reporting a contracting officer or an auditor will ask for.

Any team whose decisions run on rules over a SQL Server history will find its own migration in that sequence. ## Defence and biotech ask for the same replay San Diego builds for two kinds of reviewer. Contractors supporting NAVWAR and the Navy commands around San Diego Bay now find CMMC requirements written into Defense Department contracts, and the labs on Torrey Pines Mesa answer to the FDA's 21 CFR Part 11 for electronic records. Both want access controlled and a result that can be reproduced from the records as they stood at the time. ## Questions ### We need results a reviewer can reproduce exactly. Replay is how. The event log is the source of truth and read models derive from it, so reproducing a result means replaying to a point rather than trusting that a snapshot was taken. Defence and biotech both need that and neither accepts an approximation. ### Do you have an office in San Diego? The office is in Gilbert, Arizona, with teams in Amsterdam, Dnipro and Hyderabad. Delivery is remote or hybrid, and we travel for discovery, workshops and the opening weeks of a build. ## What software development covers ### Web applications Applications built to be changed safely years after the original team has moved on. That means tests that mean something, seams where the business logic can move, and a deployment nobody is afraid of. ### Mobile applications iOS and Android, built as products rather than as ports. The maintenance story is decided at the start, while it is still cheap. ### APIs and integration The seams between systems, done once and properly. Most of the expensive failures we are called into are integration failures wearing another name. ### Data platforms The layer underneath the application, on Databricks, Azure, AWS or Google Cloud. If the reporting and the application disagree, the platform is the reason. ### Modernisation of what exists Often the work arrives as something already built that has become hard to change. We would rather read it and tell you honestly whether it is worth keeping than sell a rewrite you may not need. ### Durable, auditable workflows Processes that take days, call several systems and must never half-complete. Getting that right is a different discipline from getting a request handler right, and it is where we spend most of our time. ## Working with us from Arizona Arizona does not observe daylight saving, so from March to November we are on the same clock as you and from November to March we are an hour ahead. Either way the working day overlaps almost completely. Most delivery is remote or hybrid. We travel for discovery, workshops and the opening weeks of a build.
