Custom Software Development
Product-grade systems built from first principles, not templates. Web platforms, internal tools and APIs your team will still be proud of in year five.
Software · AI · Architecture
Solid ground.Bold shift.
We build the software and AI systems that move ambitious companies forward — engineered to hold for the long run.
What we do
Eight disciplines. One standard: production quality.
No juniors learning on your budget. No prototypes pretending to be products. Every engagement is built by senior engineers and delivered ready for real users.
AI Agents
Autonomous systems that reason, act and report — deployed safely in production with guardrails, evals and full observability. Not chatbots. Colleagues.
AI Automation
Workflows that run themselves — humans exactly where they matter, nowhere they don't.
SaaS Development
From zero to multi-tenant platform: auth, billing, admin, analytics — ready to sell.
Cloud Engineering
Infrastructure that scales on demand and stays quiet at 3 a.m. AWS, done properly.
Software Architecture
Decisions made for year five, shipped in week one. Systems that outlive the roadmap.
Technical Audits
A clear, honest map of your codebase: the risks, the debt and the way out — in writing.
CTO as a Service
Senior technical leadership, fractional and accountable — strategy, hiring, delivery.
How we work
A process with no surprises.
You always know what's happening, what it costs, and what ships next. Radical clarity is not a value on a wall — it's the operating system.
Phase 01
Discover
A short, intense sprint to map your domain, constraints and the outcome that actually matters. You get an architecture brief and a fixed proposal — not a sales deck.
Phase 02
Architect
System design, data models and the decisions that age well. We document trade-offs in plain language so your team owns the "why", not just the code.
Phase 03
Build
A small senior team, AI-native tooling, weekly demos. Production quality from the first commit — tests, reviews and CI are never a "later".
Phase 04
Ship
Zero-drama launches: staged rollouts, observability, rollback plans. Boring on purpose. Your users notice the product, not the deploy.
Phase 05
Evolve
We measure, harden and extend. Software is never finished — it's maintained. Most clients keep us on because week one set the standard.
Why Solid Shift
Stability and speed are not a trade-off.
The industry makes you choose: the slow, safe firm or the fast, fragile shop. Our entire company is built on refusing that choice.
Senior engineers only
Every line is written by people who have shipped and operated systems at scale. We stay small so the people you meet are the people who build.
10+ yrsavg. experience
AI-native by default
Agentic tooling compounds our speed on the mechanical work, so senior judgment goes where it counts. The bar never drops — the pace does the opposite.
3×delivery velocity
Weekly shipping cadence
Working software every week, demoed live. Progress you can click is the only status report we believe in.

Meridian Freight
A decade-old monolith was throttling a national freight network. We re-architected it into event-driven services over eight months — with zero downtime migrations while 4,000 daily shipments kept moving.

AI agents · Healthcare
Caldera Health
Patient intake was drowning a 12-clinic network in phone calls. We built AI agents that handle scheduling, triage questions and follow-ups — with human escalation paths, audit trails and privacy engineered in from the first line.

Ledgerline
A founding team with a validated idea and no engineering. We took Ledgerline from architecture brief to a billing-ready, multi-tenant platform in fourteen weeks — then stayed on as their fractional engineering team.

Boring where it should be. Sharp where it counts.
We choose proven foundations and spend the innovation budget where it moves your product.

What clients say
Trust is earned in production.
They rebuilt in months what we had been patching for years — and it hasn't gone down since. The rare partner that argues with you when you're wrong.
Daniel K.CTO · Logistics scale-up
“Our agents now handle seventy percent of patient intake. Solid Shift made AI boring — in the best possible way.”
Mariana R.COO · Healthcare network
“Fourteen weeks from whiteboard to paying users. Every estimate held. I didn't know agencies like this existed.”

FAQ
Straight answers.
Every project starts with a short discovery sprint. You get an architecture brief, a fixed proposal and a timeline. From there we work as a dedicated senior team or deliver a fixed scope — your call.
Discovery usually begins within two weeks of first contact. Build starts immediately after the proposal is approved.
You do. Every repository, every credential, every document — from day one. No lock-in by design.
Two ways. Internally, AI-native tooling compounds our speed without lowering the bar — every line is reviewed by senior engineers. In your product, we build AI features and agents only where they create measurable value.
Fully remote with strong overlap across US time zones. We work in English and Spanish, with US and international clients.
Scope is defined in discovery and priced as a fixed proposal or a monthly team rate. No surprise invoices — changes are agreed before they are billed.
