Senior Developer who turns unclear ideas into working products.

I organize ideas, screens, data, and integrations so products leave draft mode and work in real life. I use React, Next.js, and TypeScript, stepping into server-side work when the project needs it.

Helping teams move from problem to delivery

My work is to understand what needs to go right, organize the technical side, and make the path clear enough to build, review, and improve with less trial and error.

Tech Base

React, TypeScript, Zod, and well-organized integrations

Mentorship

code review, mentorship, and simple team agreements

Practical AI

AI used with context, review, and validation

technical base

A clear technical base the team can evolve

I organize components, screens, data, and integrations so the product is easier to change, test, and improve. The goal is to avoid hidden improvisation and reduce rework.

Less improvisation. More clarity.

Senior hands-on work that helps the team

I work close to the code and the people: reviewing choices, explaining paths, and helping unblock hard points without creating heavy process.

Performance that improves product use

When a product feels slow or hard to use, I look at the whole path: screen, data, cache, state, and integrations. The goal is to improve both the experience and the result.

Projects where technology solved real problems

Work where I connected business needs, user experience, and code to reduce friction, create clarity, and deliver results.

Tools I use to deliver better

React, Next.js, and TypeScript are the base. Design, automation, and quality turn ideas into fast, organized products that are easy to maintain.

Backend and data

APIs, contracts, and data handled with clear boundaries.

  • Node.js
  • Hono
  • tRPC
  • PostgreSQL
  • SQLite
  • MySQL

Design to code

From planned visuals to consistent product components.

  • Pencil
  • Figma
  • Design systems
  • Tokens
  • UI review

Quality

Standards to keep pace without giving up care.

  • Jest / RTL
  • Biome
  • TypeScript
  • Zod
  • Code review

Delivery automation

Checks and templates to reduce repeated work during delivery.

  • Bun
  • Turborepo
  • CI/CD
  • Docker
  • Husky

  • Checks

delivery base

A clear technical base to evolve.

My focus is building a base the team can understand, review, and continue: consistent components, well-handled data, predictable integrations, and validation from the start.

Quality in the flow

typecheck, build, review, and a technical trail before delivery

From issue to reviewable delivery.

When AI enters the work, it is not a loose shortcut. The flow starts with a clear problem, project context, and scope boundary; then it moves through small tasks, assisted execution, technical validation, and human review.

  1. Problem context
  2. Proposal / OpenSpec
  3. Small tasks
  4. Bounded agent
  5. Technical validation
  6. Review and Done

context

Context engineering

I organize docs, project rules, decisions, and acceptance criteria before asking for execution. Less guessing, more direction.

execution

Agent workflows

I use agents to investigate, implement small scopes, and return evidence of what changed, always with clear boundaries.

validation

AI harness

I define commands, context, validations, and logs to repeat a workflow with more predictability inside the project.

governance

SDD with Linear and OpenSpec

I connect issue, proposal, tasks, validation, and closure so work leaves a technical trail and stays reviewable.

AI accelerates execution; technical decisions, architecture, and final quality stay human.

My origin became the way I build.

Before software, there were benches, electrical systems, automation, college, and São Paulo. That path taught me to respect process, people, and delivery.

Where it all began

My path into technology did not start with a polished screen. It started with trying to understand how things work, why they fail, and how to bring order back. At ETEC Jorge Street, Industrial Automation and Electrical Installations gave me grounding: care, process, and respect for detail. Later, at SPTech, Systems Analysis and Development turned that into product, code, and career.

    College gave it shape

    At SPTech, I graduated in Systems Analysis and Development. There, curiosity gained language: modeling problems, writing code, and turning study into product.

  3. São Paulo

    The city also taught me

    Growing professionally between São Caetano and São Paulo gave me pace, responsibility, and contact with different realities. I learned to listen, handle pressure, and stay present.

  4. since 2020

    Care became commitment

    I carry that origin into work: respect for who uses it, who maintains it, and who trusts that the delivery will stand.

    Product, quality, and clarity

My path so far

A short view of my path through real products, web, apps, clients, design, integrations, and now senior hands-on work at Incentivar.

  1. 2020 - 2021

    Starting with real products, APIs, and quality

    Product startStefanini

    I started by integrating screens, dealing with APIs, testing what mattered, and keeping delivery pace.

    I learned to deliver with consistency.
