Send a message, I'll solve your problem!

Websites, web systems and AI integrations — built by a senior engineer, no agency in between.

I'm Fabrício Bahiense. Since 2018 I've been shipping to production for real-estate developers, edtechs and startups — landing pages that generate leads, systems that hold up under load, AI inside the product you already have. You talk directly to me, from quote to deploy, and get a fixed scope, a date and code that's yours.

Who it’s for
Real-estate launch, campaign, new product, event. Anyone with ads running who needs the page live this week.

Page on your domain with form + WhatsApp wired, technical SEO, Lighthouse above 95, analytics set up and 3 months of adjustments. Template: you pick, I swap brand, colors and copy. Custom: structure designed for your funnel.
Timeline
template in 3–5 business days · custom in 2–3 weeks

Institutional site or portal

Who it’s for
Developers, clinics, consultancies and companies still sending clients to Instagram because the site doesn’t convince.
You get
Complete site, fast on mobile, with a CMS for your team (or static, zero hosting cost). Domain, SSL, analytics and conversion map — like I did for Conx and Passareli.
Timeline
3–5 weeks
Investment
from R$ 9.000

Web system or MVP

Who it’s for
Founders with a product in their head and a process in a spreadsheet; companies that need a dashboard, internal tool or SaaS without hiring a team.
You get
Phase 1 live: auth, database, core screens, AWS deploy (or wherever you are), docs and your own repo. Fixed scope per phase, weekly previews. Same approach as Nexus’ multichannel platform.
Timeline
first phase in 4–8 weeks
Investment
from R$ 25.000

AI inside your product

Who it’s for
SaaS, support or marketing teams that want real agents/automation (WhatsApp, email, documents) — not a FAQ chatbot.
You get
Pilot on real data: agent with memory, tools and guardrails, integrated with what you already use. OpenAI, Anthropic, Gemini or self-hosted — chosen for your cost and compliance. Cost-per-conversation report before scaling.
Timeline
pilot in 2–4 weeks
Investment
from R$ 12.000

Senior on demand

Who it’s for
CTOs or teams that need senior reinforcement: rescue legacy code, migrate to AWS/GCP, cut infra cost, review architecture before scaling.
You get
Audit: tech-debt report with a prioritized plan in 5 business days. Monthly package: fixed hours, reviewed PRs, pairing with the team. Home stack: TypeScript, React/Vue/Next/Nuxt/Astro, Node, C#, AWS.

How I work

From quote to deploy.

Four steps, no hidden stage. You know what happens, when, and what it costs before I write the first line.

  1. Conversation

    You tell me the problem (or send a link to what exists). Within 24 business hours I come back with questions or a proposal.

  2. Fixed proposal

    Scope, deadline and price in writing within 3 business days. No surprises on the invoice.

  3. Build with preview

    You follow along on a preview URL. Adjustments happen during the build, not after.

  4. Deploy + 3 months

    Live on your domain, code in your GitHub, invoice issued, and 3 months of adjustments included.

You get

  • fixed scope
  • a deadline
  • code in your repository
  • contract and invoice
  • 3 months of adjustments

About

Code is only half the job. The other half is understanding the problem before writing the first line.
