InflexDev is a one-person software studio: eleven years of production software, the last five on financial platforms. AI agents write the drafts; I review every change before it merges. Fixed scope, published prices, and you own the code from day one.

Review fee credited in full toward the build. You own the code, accounts and IP from the first commit.
Anyone can generate an MVP now. The hard part starts when it meets real users, real money and the systems you already run.
Your MVP works in a demo. I make it survive real users: authentication, permissions, data model, error handling, deploys and the security review it will eventually face.
A production system you can hand to a security reviewer.
LLM features and agents wired into your existing services through tools and MCP, with clear lines between what the model decides and what your code enforces. No rewrite.
Agents that call your systems through scoped, logged tools.
Payments, ledgers, webhooks and customer data, built so retries never double-charge, events reconcile and every change is traceable.
Idempotent flows, reconciliation and an audit trail.
No discovery phase that never ends and no weekly status theater. Agents compress the drafting; the review and the decisions stay human.
The paid review. I read the code, the data paths and the accounts it runs on, then write a brief and a fixed-scope milestone proposal.

One- to two-week milestones. Agents draft, I review every change before it merges. Each milestone is demoed and paid on its own; changes to scope are agreed in writing.

Production cutover and handover. You get the runbook, the architecture notes and a recorded walkthrough, then 30 days of support.

Founder experience from contract work before InflexDev. Client names are withheld. Each one keeps a clear line between what the AI decides and what the code enforces.
B2B services company
An analytics assistant that answers from the company’s own data. Any useful answer can be saved as a dashboard that keeps itself up to date.
GuardrailsThe AI chooses which approved query to run. The code limits what it can read, logs every step and stops after five.
B2B services company
A connector that gives managers five operational tools inside Claude, so there is no new app to learn and no SQL to write.
GuardrailsThe AI picks the tool. The code fixes the tool list, checks every input and limits what each tool can reach.
B2B services company
An AI builder that writes the screen, previews it safely and publishes a new version only after it passes checks.
GuardrailsThe AI writes the screen. The code validates it, versions every publish and sandboxes the preview.

Every engagement starts with the review. It is worth doing on its own, and its fee comes off the build if you continue.

A one-person studio should leave nothing behind that only one person understands. The handover kit is written so another senior engineer can take over without me.
Five years on financial platforms: claims portals for securities class actions, investor portals and reporting, account-suitability tools. Intake, distributions, ledgers and reconciliation on licensed rails. I never hold or move funds.

I’m Everton Almeida. I have spent more than eleven years building production software on .NET, AWS and Azure, the last five on financial platforms, most recently as a tech lead. Today I design and ship AI agents that work inside a company’s own systems.
Every build runs the same way: specifications first, agents for the drafts, my review on every change. There is no account manager and no hand-off to a junior team. You talk to the person who writes the brief and approves the merges.
InflexDev is a Delaware company. I work US business hours, remotely.
