Senior engineers for companies of every size: custom web and mobile apps, AI features and agents, automation, security, and the growth around them, plus ongoing maintenance once you are live.
// you own every line await deploy(app, { owner: "you" })
The edge is the work where a mistake cannot be undone: migrations, auth, payments, security, production uptime.
You can retry a feature. You cannot retry leaked customer data, a migration that destroys your records, or an auth layer that exposes other users' data.
// entitlement-scoped access — the 20% AI skips export const getRecord = defineTool({ name: "get_record", handler: async (input, ctx) => { if (!ctx.can("read", input.id)) throw new Forbidden(); // RLS, enforced return db.records.find(input.id, ctx.tenant); }, });
Our core. Web apps, SaaS development, dashboards and internal tools — the software you can't buy off the shelf, built production-grade in code you own. We also rescue and harden existing apps (AI app rescue).
the main craft →Claude, OpenAI or Gemini in your product — RAG, MCP servers, copilots and AI agents, with the error handling and cost control demos skip.
AI that ships, not just demos →Cybersecurity reviews, SOC 2 readiness and accessibility remediation — find the gaps before an attacker, an auditor or a lawsuit does.
secure it properly →Automate the manual work inside your business — internal ops, data pipelines and integrations — with n8n, Make, or custom code that doesn't quietly break.
hours back, every week →One React Native codebase, two app stores; Next.js on the web. We design, build and ship — for a fraction of the cost of separate native apps.
iOS + Android + web →Landing pages that convert, technical SEO built into the code, and paid campaigns — the growth layer wrapped around your product, whoever built it.
the compounding layer →An air-gapped RAG platform, shipped end to end. Every number is one we can walk you through.
$ codessavvy audit ./app --report ✓ auth: bypass on /admin — password in bundle ✓ data: RLS disabled on 3 tables ✓ infra: no backups on primary database ✓ errors: 0% of failures reported verdict fixable in place — no rebuild next migrate → own Supabase, enable RLS # short written verdict in your inbox
A few engagements we can walk through end to end. Client identities protected under NDA; the work speaks plainly.
A RAG platform for a corpus that legally couldn't leave the client's network. Hybrid retrieval, fabricated-citation rejection, and a four-metric quality harness — proven with the network cable pulled.
Field photos become client-ready PDF reports through a ten-step pipeline — five independently deployed services with error tracking on every one.
A founder's data was locked inside Lovable. We moved it to infrastructure he owns, then built his entire permission system — the last-20% auth layer AI tools skip. He returned for the next phase.
A live admin endpoint was throwing 500s. On a first engagement we had — and should have had — no hosting or error-tracking access. We installed observability, diagnosed from the repo and logs alone, and never touched a production secret.
The engineer who scopes your project builds it. No account managers, no junior handoff after you sign.
Hourly billing is a blank check. You get a fixed price on a written scope. Scope changes are priced in writing before any work starts.
Your code lives in your GitHub from the first commit. Your cloud, your keys. Never held hostage.
A staging URL you can test, not a status report. Problems surface in week two, not week ten.
30 minutes. You tell us what you're building. We ask the hard questions and say honestly if we're not the fit.
Within 48 hours: every feature, every exclusion, one fixed price. No code until you approve it.
Every Friday a staging URL with working software. You test, we adjust. No black box.
We deploy, wire up monitoring, document everything, and hand over every repo and credential.
A senior engineer reviews your app — auth, security, data integrity, scale — and sends back a written report: what to fix, a fix-or-rebuild call, a rough cost, and which CodesSavvy service fits. Send the form and we reply with a payment link. Your report arrives within 3 business days of payment and of receiving any access you agreed to give us. The $199 comes off any CodesSavvy service you book within 60 days of the report. See the Launch-Readiness Review or pricing.
