The studio.
One engineer. One LLC. Years of compounded decisions and shipped systems.
Sage Ideas LLC was founded in 2024 with a specific thesis: that the right process, the right infrastructure, and AI-native development practices allow a single practitioner to build and ship software at a quality level that matches a small agency — with the added benefit of direct accountability.
Before the studio, Jason Teixeira spent five years as a fintech engineer at HighStrike (2021–2026) — building trading infrastructure, market data systems, and real-time financial applications that handled production load. That's where the engineering discipline came from: systems that don't fail on a volatile trading day demand a level of rigor that carries over into everything since.
The studio operates out of Orlando, FL. Remote-first by default.

Small by design. Systematic by necessity.
Living architecture
Build ⇄ Operate
The studio is intentionally small, so the operating system has to be serious: repeatable scope, production gates, clear handoff, and content that compounds.

How we think about the work.
We build what we operate
Every service offering at Sage Ideas is something we use ourselves. The infrastructure patterns we sell are the same ones running our own products. The AI workflows we build for clients are the same ones powering our lab. We don’t pitch theory — we ship proof.
AI-native by default
We don’t bolt AI onto existing workflows. We design systems where AI acceleration is assumed from day one — in code generation, in testing, in content pipelines, in customer-facing features. This isn’t a trend we adopted; it’s how we’ve built since 2024.
Solo studio, agency rigor
One person running a production-grade process: CI/CD gates, contract testing, Lighthouse budgets, accessibility audits, security scans, idempotent webhooks, RLS policies, SOC2-aware architecture. The output is indistinguishable from a five-person agency, shipped on a solo timeline.
How the studio works.
Clients work with Jason directly — not an account manager, not a project coordinator, not a handoff to a handoff team after the sales call. The same person who scoped the project is the person building it. That accountability is structural, not a feature we sell.
Every engagement follows the same methodology: Discover → Architect → Build → Operate. The scope is defined in writing before work begins. The price in the proposal is the price you pay — no "starting from," no surprise overages.
Engagements are productized by tier: Audit ($1,500), Ship (from $5,000), Automate (from $8,000), Build (from $25,000), Scale, and Operate. Each tier has a defined scope and defined deliverables. You know what you're getting before you sign anything.
Larger agencies have their place — complex team coordination, ongoing managed services at scale, 24/7 support organizations. For discrete software products, AI workflows, and infrastructure architecture, a studio of one with the right process is faster, more accountable, and more consistent.
The values, plainly stated.
Ship over present.
We prefer working software over polished decks. Every engagement ends with deployed, tested code — not a recommendations document.
Evidence over assertion.
We don't claim quality. We document it. Test suites, Lighthouse scores, CI gates, cert verifications — the evidence is always available.
Fixed scope, honest price.
We've seen what scope ambiguity does to client relationships. Every engagement has a scope document. The price in the proposal is the price you pay.
Build to last.
We build systems we'd be comfortable maintaining in two years. TypeScript strict mode, documented architecture decisions, runbooks for failure modes.
What we don't do.
Self-qualification matters. These are honest limits — not failures, just not the right fit for this studio.
Enterprise sales engagements (six-month procurement cycles, vendor panels)
Agencies-of-agencies (no subcontracting the work to another team)
Design-only engagements (brand decks, mockups without implementation)
Native mobile-first builds (iOS/Android apps as the primary deliverable)
Support-only retainers (helpdesk, ticketing, on-call without a build component)
