Backend Developer · Software Engineer

Building APIs since 2023

I write backends. Mostly Go and Node. Mostly the kind of code you don't need to re-read three times to understand.

About

I build backend systems someone else can still read a year later. Boring is a feature.

I've worked across startup and SaaS backends. OAuth2 flows, multi-tenant data models, third-party integrations, both Postgres and Mongo. Most of the hard calls happen in the data model. Get that right and the rest is mostly typing.

Outside of work I read papers more than blog posts, and I spend time understanding how databases and message brokers actually work, not just how to call them.

  • APIs in production

    multi-tenant, billing, e-learning

  • Go · Node · TS

    primary stack

  • Readable by default

    small units, explicit edges

Experiences

  1. Backend Developer

    Bifora Consulting (Remote)

    Working on a multi-tenant SaaS platform. Backend architecture, data modeling, REST APIs end-to-end, and chasing latency on the hot paths when it matters.

  2. Mobile & Backend Developer

    Fihary Soft

    Shipped features across both the mobile apps and the backend behind them. Spent a fair amount of time breaking up legacy modules into pieces small enough to test, and unblocking the release flow.

  3. Full Stack Developer

    Mesupres

    Built an e-learning platform from scratch. Interactive learning paths on the frontend, secured REST APIs and a properly normalized Postgres schema on the back.

  4. Full Stack Developer

    In_IT

    Built end-to-end web products with Next.js on the front and Spring Boot on the back. Worked across feature design, REST APIs, data modeling and the day-to-day plumbing of getting features in front of users.

Manifesto

I build for the engineer who will inherit this codebase next year.

Small units. Explicit boundaries. Code that doesn't need a tour guide six months later.

Auth SaaS with Go

Auth service in Go over gRPC. Token issuance, OAuth2, account store on Postgres. Comes packaged in Docker so you can self-host it.

Private Chat

NDA

Real-time chat built around privacy. Anonymous sessions, messages that disappear, a Redis transport that keeps nothing it doesn't have to.

ZenPath

Small Go CLI. You point it at a folder, you give it rules, it sorts files for you. No daemon, no GUI, just the binary.
