Software development for San Diego companies
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.

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.
TechFabric is a Databricks partner with an award-winning Databricks engineering team, 80 of them Databricks-certified, and a Temporal partner. Where a system reaches past the workspace we build on Azure, AWS and Google Cloud.
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.
App development in San Diego
Biotech, defence and wireless apps here have long development cycles and no tolerance for an unexplainable result. We build the app with provenance under it, so a number on the screen can be traced back to the instrument that produced it.
Mobile app developmentDynamics 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.
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.
The usual answer is a snapshot taken at month end and a spreadsheet saying which version fed which report. Reviewers stop trusting that the first time a number moves. We'd make reproduction a property of the platform, with every table versioned and every result tied to the version it read, so rerunning last March's analysis gives last March's answer without relying on anyone's memory.
We start with one result somebody has already been asked to reproduce, trace it back through the pipeline, move those tables onto Delta with retention set to cover your review cycle, and record lineage in Unity Catalog. If the rerun matches, that path becomes the pattern for the rest, and if it doesn't, the mismatch shows the real scope.
Clients we have done this for
Synapse and SQL Server gave way to Databricks Lakehouse and Lakebase at Location Services, cut over in reversible waves, and the rules engine that validates a repossession assignment on arrival now runs against governed lakehouse data. Any team whose decisions run on rules over a SQL Server history will find its own migration in that sequence.
Automotive / Fintech
Location Services
Location Services' repossession platform automates assignment intake, so fewer people handle each case, and our engineers built it with the company's own technology team. When it was time to leave Synapse and SQL Server, we moved it onto Databricks in waves that could each be rolled back, and the rules engine that checks every assignment came through unchanged.
How an engagement runs
01
A technical conversation
Not a sales call. An engineer, asking what you are trying to do, what has been tried and what it will actually take. Where the work needs them, product and design people join the same conversation.
02
Two weeks, fixed fee
A short assessment ending in a written plan with a scope, a sequence and a number. You own the document whether or not you carry on with us.
03
Build with your team in the repo
Senior throughout, and no pyramid with one architect over a floor of juniors. The person in your standup is the person writing the code.
04
Run it
We stay on the pager. Nobody designs a fragile thing they will personally be woken by, which is most of why this arrangement produces different software.
Two weeks, fixed fee, and a written plan whether or not you build it with us.
Tell an engineer what you want to build
A senior engineer reads it and replies within one business day, usually with the questions that decide the first two weeks.
Around San Diego
From Sorrento Mesa to Little Italy
The San Diego Python Users Group meets on the fourth Thursday of the month in Qualcomm's Building Q in Sorrento Mesa, and streams the talk for anyone who can't make the drive. JavaScript developers gather in Little Italy instead, at Edge on the second Wednesday, and the San Diego JavaScript Community has run close to 600 of those evenings. iJS returns to the Hyatt Regency La Jolla in May 2027.
The split is a fair picture of a lot of the software built here. The data side has to trace a number back to the instrument or the test that produced it, and the screen side has to show that number to a lab manager or a contracting officer without rounding its history away. When different teams build the two halves, the join between them is where an audit tends to find the gap.

San Diego Python Users Group
Talks are streamed and Saturday study groups run online, so a remote team can follow the same Python conversation as engineers in Sorrento Mesa.

San Diego JavaScript Community
Nearly 600 evenings in, this Little Italy meetup is where the people building the screens that show a lab's numbers learn from each other.

FAQ
Software development in San Diego: common questions
Do you work with San Diego companies?
Yes, and with companies across the United States. 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.
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.
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.
What kinds of custom software do you build?
Web applications, mobile applications, APIs and the data platforms underneath them. The work we do best is the sort that has to be governed and auditable, where a wrong write is expensive and somebody has to be able to explain afterwards what changed and why.
Do you take over an existing codebase?
Often, yes. A good part of 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 you a rewrite you may not need.
