# About Giovanni Sandrini

Title: Engineer · Systems Thinker · Builder
Location: Itajaí, BR
Bio: I build products from the ground up and see them through to production —
across mobile, web, and backend.


## Summary
Five years shipping across e-commerce, logistics, and B2B. My work spans
Flutter, TypeScript, and Node.js, but the common thread is ownership — I
care about the whole system: architecture, UX, rollout, and the metrics
after it ships. I'm at my best in problems where the engineering and the
product decision are part of the same conversation.

## Experience
### Product & Platform Engineer — Yandeh (2025 – present)
Business Tech in Retail — $100M annual GMV, 500+ sellers. Shipped
across multiple product surfaces including Midia Pro, SmartCare, and
Abastece Shop. Architected and launched an AI-driven workflow to turn
campaign inputs into promotion-ready assets, cutting production time
by 95% (60 min → 3 min). Owned revenue-critical flows across Flutter,
Nuxt, and Node.js APIs, including payment improvements that increased
conversion by up to 10%. Strengthened modular architecture, custom
state management, and multi-platform support to reduce regressions and
make releases and onboarding faster.
Stack: TypeScript, Nuxt, Flutter, Node.js, AI Workflows, Payments
- Cut promotional asset production time 95% (60 min → 3 min)
- Owned payment flow improvements across app and APIs; +10% conversion
- Improved modular architecture and state management for safer releases
- Supported multi-platform evolution across mobile, web, and desktop
### Software Engineer — Gruppe (2024 – 2025)
Software house serving 50 logistics clients. Built and maintained a
seller-facing CRM processing 100+ orders/day and over $1M/month in
operations. Engineered and scaled a serverless Node.js backend that
cut infrastructure costs by 30%. Strengthened the product foundations
around auth, session handling, typed networking, caching, and error
flows. Designed a dynamic discount rules engine on top of a NoSQL
model, enabling targeted campaign logic that the previous software
could not support. Translated complex logistics requirements into a
technical roadmap with 100% on-time delivery on critical milestones.
Stack: Node.js, AWS Lambda, Flutter, NoSQL, Serverless, CRM
- Processed $1M+/month in orders
- Cut infra cost 30% via serverless rearchitecture
- Built dynamic discount rules engine for targeted campaigns
- 100% on-time delivery across critical milestones
### Mobile Engineer — Tecadi Labs (2023 – 2024)
Logistics operator with 300K+ m² of warehousing. Delivered an
offline-first checklist platform used across 100+ daily field
operations, with configurable templates and resilient sync for
low-connectivity environments. Implemented a modular white-label
architecture with reusable flows and branding layers, improving reuse
across clients. Integrated Google ML Kit to support cargo inspections
with real-time image and data analysis, cutting manual verification
time by 75%.
Stack: Flutter, Offline-first, ML Kit, Clean Architecture, White-label
- Supported 100+ daily field operations with resilient offline sync
- Built modular white-label architecture for reuse across clients
- Cut manual cargo verification time 75% via ML Kit integration
### Mobile Engineer — GASS (2021 – 2023)
Restaurant management consultancy. Built a Flutter app consolidating
60+ management tools into a single experience for 200+ B2B clients.
Delivered no-code MVPs to validate new workflows quickly, then moved
the strongest ideas into the product roadmap. Also led enablement with
consultants so client onboarding and adoption stayed consistent as the
app expanded.
Stack: Flutter, Firebase, No-code MVPs, Enablement
- Consolidated 60+ tools for 200+ B2B clients
- Turned validated no-code MVPs into product roadmap inputs
- Trained consultants to improve rollout consistency and adoption

## Skills
Primary: TypeScript, Dart, Flutter, Node.js, React, Nuxt
Secondary: NestJS, PostgreSQL, Redis, AWS Lambda, Firebase, Docker, CI/CD, Vue, Serverless
Currently learning: MCP, edge runtimes, AI agentic workflows
I reach for the boring, durable solution first. AI shows up when it
removes real work, shortens feedback loops, or makes a product more
useful — not as decoration.

## Projects
### know-me
Open source package for developer portfolios, combining a chat widget and MCP server so profile data can be queried directly by AI tools.
Stack: TypeScript, React, MCP
### Midia Pro
Product workflow for generating campaign-ready promotional assets with dramatically shorter production time and tighter iteration loops for commercial teams.
Stack: TypeScript, Nuxt, Flutter, Node.js, AI Workflows
