San Diego, CA · Custom Software + AI

Custom software for San Diego — built the AI-native way.

We pair senior engineers with an AI-accelerated delivery model to ship custom software for San Diego's biotech, defense, and telecom operators — without the fragile output that gives AI a bad name.

Senior-only engineering · AI-accelerated delivery · you own 100% of the code

AI changed the economics of custom software. We rebuilt our process around it.

San Diego is the country's largest biotech and defense-tech cluster outside the DMV, with a deep telecom heritage (Qualcomm), a fast-growing SaaS scene in Sorrento Valley and downtown, and serious life-sciences capital. Senior hires are six figures, months out, and picked over by biotech, defense primes, and a rotation of venture-backed challengers. AI changes the math, but only when senior people own the parts AI gets wrong.

On a San Diego biotech, defense, or telecom build, AI handles the repetitive 70% — schemas, scaffolding, glue, dashboards, lab-data UI. The 30% AI gets wrong is the part your validation, security, or regulatory team will absolutely catch: e-signatures missing under 21 CFR Part 11, audit trails that don't cover a PHI access, integration boundaries on the unclassified side of a contract, and assumptions about radio or low-power constraints AI doesn't understand. Raw AI output skips those silently.

We build for San Diego operators — biotech and pharma companies digitizing lab and trial workflows, defense and aerospace contractors shipping into milestone schedules, healthcare and clinician tools, and B2B SaaS scaling to regulated buyers. Our model: AI handles scaffolding and the repetitive 70%; a senior engineer owns architecture, security review, and signs off on every change.

Show, don't tell

AI writes the first draft. A senior engineer signs off.

Every change runs through review for security, tests, and architecture before it ships — that review is the product.

On a San Diego biotech or defense build, the failure modes are missing e-signatures, audit-trail gaps on PHI, and boundary leaks between unclassified and classified work. Senior review catches them before a validator or a security officer does.

What we build for San Diego companies.

Bio / Life Sci

Biotech & lab software

LIMS extensions, trial-management tools, and AI for research pipelines, validated for regulated environments.

Defense

Defense & national-security software

Mission tools and analytics built for the security, classification, and integration standards your contracts require.

Healthcare

Healthcare & HIPAA-ready apps

Patient-facing portals, clinician tools, and care-coordination platforms built to HIPAA from day one.

AI

AI applications

Copilots, RAG, search, and agents grounded in your data, with guardrails and evals.

Product

SaaS platforms

Multi-tenant products with auth, billing, and dashboards — MVP to scale.

Internal

Internal tools & copilots

Operations tooling that replaces the spreadsheet-and-tribal-knowledge workflow.

Senior, on-shore, AI-accelerated

A senior team that moves at AI speed.

You work with senior engineers in Pacific Time who own architecture, compliance posture, and code quality for regulated work — fitting into a La Jolla biotech, a Sorrento Valley defense subcontractor, or a downtown SaaS rhythm — not a junior pool with raw AI output bolted on.

From La Jolla to Carmel Valley to downtown, senior engineers are split between biotech, defense, and Qualcomm — and increasingly drawn into remote coastal roles. An AI-native team gets you shipping this week, scales monthly, and doesn't compete with biotech-scale comp packages.

Common questions from San Diego teams.

Do you work with San Diego companies?
Yes — we serve San Diego, Chula Vista, and Irvine companies with senior, on-shore engineers in Pacific Time. Most collaboration is remote-first, with on-site available for kickoffs and key milestones.
Do you work with regulated bio / defense environments?
Yes. We architect for HIPAA from day one in healthcare; for defense, we structure the unclassified portion of the work so it integrates cleanly with your cleared team's contributions. We don't deliver ATO or GxP; we build code that survives your auditor's review.
Can you separate cleared from uncleared work cleanly?
Yes. We work on the unclassified surface of your scope — public-facing UI, integration to non-classified data, internal tooling — and we structure handoffs to your cleared bench with explicit boundaries, documented data flow, and clear ownership lines. No leakage; no overlap.
Is AI-built software production-ready?
Yes — when a senior engineer reviews every output, adds tests, and hardens it. The horror stories come from shipping raw AI code unsupervised. We don't, and we support what we ship.
Will we own the code?
100%, from day one. We deliver to a repository you control — no proprietary platform, no lock-in.
How fast can we start?
Usually within days. A short scoping call defines the build, the timeline, and a fixed quote.
Can you work with our existing team?
Yes — we augment in-house teams, review their work, and set standards, or run the build end to end. We flex to how you work.
