Financial Control Center

Financial domain, architecture & product

A personal finance control center that models real available money, debt, commitments, savings and projections without confusing balance with spendable cash.

What it solves: It is my own project and it solves a problem of my own: knowing how much I can really spend each month without neglecting installments, savings and commitments. I defined it and built all of it; the schema has 23 models and 17 enums.

Lore

I'm a Computer Engineer and software developer at GreenSoft. I build interfaces for environmental products, automation and AI integrations; earlier I worked in process auditing at PwC and built LEXY as a team capstone.

My foundation is React, Next.js and TypeScript. From there I move into backend, data, business rules and deployment when the product needs a complete solution.

What people ask me

Quick answers

I work as a software developer at GreenSoft, building environmental products, automation and AI integrations. I also maintain personal projects where I explore new ideas and technologies.

My specialty is React, Next.js and TypeScript. Depending on the product I also work with Node.js or Laravel, PostgreSQL/Prisma, APIs, authentication and local-model or AI-service integrations.

Yes, upper-intermediate level (TOEIC 805). I'm comfortable working in English-speaking teams.

Products where the interface, business rules and integrations form one coherent solution. AI interests me when it removes manual work or improves a decision, not as decoration.

I start by understanding the problem and modeling its rules. I work incrementally, document important decisions, validate with tests and collaborate across product and engineering to ship the solution.

Let's talk

Let's work together?

I'm open to Frontend, Full Stack and applied-AI roles where I can contribute product judgment, React, Next.js, TypeScript and end-to-end integrations.

Always open to a good conversation

LinkedIn

I work mainly with TypeScript, React and Next.js. Some work projects don't have a public repository for confidentiality.
