I implement integrations with marketplaces such as Shopee, TikTok Shop, and Mercado Livre; e-commerce platforms such as Shopify; and ERPs such as Bling. - I implement integrations with carriers such as Mandaê, J&T, FM Transportes, and Correios. - I contribute to a platform that processes more than 50,000 orders per month across e-commerce and marketplaces, with status normalization, queues, and WhatsApp and email notifications. - I build new features and maintain the backend and the operations dashboard with NestJS, React, and asynchronous processing, meeting customers' needs. - I am expanding my role into sales and marketing, in addition to product development and operations. **Talentei** - I conceived and built the B2B recruitment and selection SaaS with psychometrics and AI, from database to UI, with a multi-tenant architecture, PostgreSQL, Drizzle, Next.js, and TypeScript. - I implemented resume OCR and job-fit analysis, selecting GLM, DeepSeek, and OpenAI models via OpenRouter, with BullMQ and Redis queues. **Internal platforms and automations** - I built an HR platform with payslips, timesheets, automated emails, and role-based access control (RBAC), using Next.js and Node.js. - I implemented a mismatch dashboard across Mercado Livre, Tiny, and Bling, and dashboards with the Google Sheets API to support operations. ### Front-End Developer, Spadoni Projetos Aug 2024 – Sep 2024 - I redesigned the company website with HTML, CSS, and JavaScript, responsive navigation, a form via EmailJS, and WhatsApp contact. ### Machine Setter and Operator, Plasticogeral Embalagens Dec 2022 – May 2025 - I progressed from line feeder to level III operator and machine setter. I trained more than 10 colleagues in the operation and assigned the afternoon shift's tasks. ## Work: Two products in production. ### Kanglu In production · On the Enviagora team · More than 50,000 orders per month · https://app.kanglu.com.br Tracking SaaS for e-commerce: one delivery timeline for merchant and customer, with automatic notifications at each step. - **Problem:** Order shipped, the customer asking “where is it?”, and the merchant opening each carrier's site to find where the delivery stopped. - **What I built:** Bling (ERP) and J&T (carrier) integrations, status normalization into a single timeline, WhatsApp and email notifications per step, Redis queues, journey rules, and shipping dashboard screens. - **Outcome:** Customers are notified along the journey and the merchant sees shipping in one dashboard, not in carrier tabs. - **Stack:** NestJS, TypeScript, PostgreSQL, Prisma, Redis, React, Vite ### Talentei In production · End to end · https://talentei.com.br B2B recruitment SaaS with AI: jobs, pipeline, psychometric tests, and candidate × job × leader × culture matching. - **Problem:** Recruiting in spreadsheets and inboxes: scattered resumes, gut-feeling screening, and no record of why a candidate moved forward or stopped. - **What I built:** From database to UI. Multi-tenant with per-company isolation in PostgreSQL; DISC, Enneagram, and 16P tests with public links and PDF; resume extraction and matching on BullMQ/Redis queues, outside the request; LGPD as a flow, with consent and a candidate portal. - **Outcome:** Screening becomes a process with criteria and a trail: the recruiter opens a decision queue instead of digging through email attachments. - **Stack:** Next.js, React, TypeScript, Bun, PostgreSQL, Drizzle, Redis, BullMQ, Better Auth ## Hackathon awards ### 1st place, DevDay Community Hackathon São Paulo (October 2026) Team development of Quebra-Gelo, a project that turned the event's networking into a gamified experience.

That is where my impatience with processes that only work if someone remembers to run them comes from. Today I write the code, set up the server, and look after what runs afterwards: backend, frontend, database, queues, and the VPS where it all stays live. As AI advances, developing is no longer just code: it is thinking about the product.
