Hello there! My name is Alisson.
I'm Cofounder & CTO at Nock and a Product Engineer at Salvy (YC W24). Before that, I worked at another Brazilian startup as a full-time software engineer and was an undergraduate research assistant in Deep Learning at PUCPR, where I study Computer Science.
Since 2025, I've run the Builders Club, a programming and product club at my university that more than 60 students have come through.
I was nominated two years running for the Dean's List of the PUCPR Polytechnic School in recognition of my academic performance and for standing out across several areas of the university.
Projects
Nock
Brazil's GTM infrastructure. Nock finds people and companies, enriches contacts through a waterfall and runs outreach over LinkedIn and email. Work happens in a spreadsheet or through an agent, in the dashboard or over WhatsApp. So far we have a R$ 4,000 grant from PUCPR's PIBEP program and an enterprise customer: Gupy.
ContentLayer
ContentLayer is the content layer for any SaaS. It turns features and updates you have already shipped into posts backed by real recordings. The agent opens the product, tests it and records videos of the feature on its own. You just review and post.
dominio.cheap
Domain price comparison. Shows on one screen, in Brazilian reais, what it costs to register, renew and transfer a domain at registrars such as Hostinger, GoDaddy, Porkbun and Registro.br. It also works as an MCP server, so agents can look up prices.
Fault-Tolerant Game Server Architecture Using Elixir and OTP
Paper written for the UNIGOU Remote Program 2026, run by INCBAC, the Institute of Czech-Brazilian Academic Cooperation. In the server, every player, zone and dungeon is a supervised process. With faults injected, recovery stayed under 400 microseconds and 100,000 concurrent players took up less than 1 GB.
Builders Club
Site for the PUCPR programming and product club. Every element on the page is draggable, and images take grayscale, sepia, invert and blur filters implemented twice, in Rust compiled to WebAssembly and in plain JavaScript, with a popup timing both runs. React 19 and Vite. The live-demo branch is the version presented at ReactCWB.
dsa_hkc
C library of data structures, written by two PUCPR students. Linked lists, stacks, queues, binary trees and hash tables, installable system-wide with make install and consumed from other CMake projects through find_package. Documentation generated with Doxygen.
pigment.nvim
Neovim colorscheme derived from the palette of the 1895 Hull House Maps. Three modes: vintage on warm paper, a low-contrast dark, and canvas on pure white. Ships matching themes for Lualine, Alacritty and Tmux.
