Software Engineer with a technical foundation and a practical product mindset
I have studied programming since 2015 and use this space to document lessons, tools, and practical projects.
I am Bruno Paim, a Software Engineer interested in building interfaces, integrations, and digital solutions with technical clarity and practical value.
My experience spans frontend and full-stack software engineering, automation, API integrations, and applied AI studies. brunopaim.tech exists to gather that process in my own space.
The focus here is to share studies, tools I have been testing, behind-the-scenes notes from the software engineering routine, and projects in progress.
01 / Professional experience
A career built across product, code, and operations.
Each stage expanded a different part of my work: from full-stack software engineering to frontend architecture, automation, data, infrastructure, and AI applied to real products.
01NEOTSenior Software EngineerFeb 2025 — presentFeb 2025 — present
I joined NEOT at an early stage as the company’s third team member, working alongside the CEO and tech lead. I started in a part-time, frontend-focused role and, since June 2025, have expanded my scope to deliver full-stack products with high autonomy, from requirements and user journeys to data modeling, backend services, and interfaces.
highlights from this stage
- I lead frontend architecture across five Vue 3 and React Native products, establishing reusable patterns, technical standards, and quality practices that support the portfolio’s evolution.
- I designed and implemented a new legal and financial opportunity-management product end to end, from early requirements to its upcoming first customer rollout, using Vue 3, Python, FastAPI, Nameko, RabbitMQ, Redis, MySQL, MongoDB, and Neo4j.
- The product brings together role-based dashboards, user and team management, access control, opportunity and deal workflows, Kanban pipelines, SLAs, approvals, relationship mapping, and AI chat integration.
- I designed a spec-driven workflow used across the company’s web products, combining eight specialized agents, versioned specifications, Vitest, Playwright, automated quality gates, and final human review.

02Sinapsis Inovação em EnergiaSoftware EngineerMar 2024 — May 2025Mar 2024 — May 2025
At Sinapsis, I worked on energy platforms with large datasets and geospatial interfaces. It was a stage where frontend performance, cost decisions, and backend processing had to move together.
highlights from this stage
- Lazy-loading and rendering optimizations reduced a visualization with more than 1,000 markers from about three minutes to ten seconds.
- I migrated cost-sensitive projects from Google Maps to Leaflet, increasing control over the geospatial layer.
- I also developed Java services with Spring and Hibernate and worked with Oracle and PostgreSQL.

WP03WhatsApp-integrated platformSoftware Engineer · FreelanceSep 2023 — Feb 2024Sep 2023 — Feb 2024
The challenge in this contract was to move conversations and lead distribution away from isolated account access and into one operation. I built a web platform that centralized customer service, routing, and data intake.
highlights from this stage
- I implemented the interface and services with React, Material UI, Node.js, MySQL, and Sequelize.
- I built Excel imports and synchronization workflows for lead intake and distribution.
- I also handled Linux deployments, updates, troubleshooting, and ongoing production support.

04Onisys Na EstradaSoftware EngineerJul 2022 — Aug 2023Jul 2022 — Aug 2023
At Onisys, software was directly connected to road-transport safety. I worked on applications that brought trips, telemetry, training, and risk events together to make daily operations more visible.
highlights from this stage
- I built responsive dashboards and monitoring workflows with React and Redux.
- I implemented services and data models with Node.js, Sequelize, and MySQL.

05loc XSoftware EngineerMar 2022 — Jul 2022Mar 2022 — Jul 2022
At loc X, beyond the features of a B2B real-estate platform, I faced a migration problem spread across approximately 100 GB of PDFs, spreadsheets, and CSV files. I turned that heterogeneous dataset into a reproducible search, extraction, and import workflow.
highlights from this stage
- I developed features with React, .NET, and MySQL and data automation with Python.
- Searches that took hours began returning in seconds.
- The automation reduced an estimated six months of manual work to about two weeks.

06Francisco ImóveisSoftware EngineerOct 2021 — Mar 2022Oct 2021 — Mar 2022
At Francisco Imóveis, automation became part of my daily work. I connected systems and channels that previously depended on manual tasks while also taking ownership of Linux production operations.
highlights from this stage
- I automated email and WhatsApp notifications and connected Google Sheets data to custom APIs.
- I built real-time synchronization for more than 15 Pipefy boards with GraphQL, Node.js, Python, and MySQL.
- I managed AWS EC2, Apache, PM2, logs, backups, webhooks, Bash scripts, and cron jobs.

02 / Beyond the classroom
Research, outreach, and university life are part of the story too.
Before and throughout my career, research, teaching, community, and technical-support projects helped bring theory, practice, and people closer together.

Some studies also gain a voice, context, and a demonstration.
On YouTube, I turn research and experiments into videos about tools, projects, and technical decisions. It continues what I document on the blog while giving me another way to show the process.
