Gabriel Dalmolin | Full Stack Software Engineer Focused on Backend Systems

Professional profile

Clarity under operational pressure.

How I approach backend systems and integrations when ambiguity quickly turns into operational cost.

+6 years of experience

How I build

Explicit systems age better under pressure.

That principle guides the backend platforms, integrations, and internal tooling I build.

Most of my work sits around authentication, billing, integrations, and internal platforms, where ambiguity quickly becomes product and operational cost.

I look for contracts that stay clear, workflows that stay inspectable, and infrastructure that keeps its shape once asynchronous behaviour, edge cases, and delivery pressure begin to stack up.

Signals of scale

Operational scale, made visible.

A few signals of the operational scale, responsibility, and commercial context I have already supported in production.

Production context

Systems and workflows that already had to operate with real volume, predictability, and commercial context.

04 signals

Revenue Supported

Revenue-critical systems

01

+10million

Systems and workflows behind more than eight figures in marketplace revenue.

Built around reliability, throughput, and operational control.

03

ReliabilityObservabilitySafe change

Core stack

The environment behind the systems.

The technical environment that shows up most often when the work needs steady runtime behaviour, explicit integrations, and sustainable delivery.

Working set

Runtime, data, systems languages, integrations, and delivery patterns chosen for serious backend work.

18 tools

Operating profile

Backend-first delivery

A backend-first environment tuned for APIs, asynchronous workflows, observability, and safe change.

Technologies chosen for runtime stability, integration clarity, and maintainability under real delivery pressure.

Core field

Infrastructure, runtime, and delivery.

An intentional mix of languages, frameworks, data, containers, and operational tooling.

APIsObservabilitySafe change

Runtime canvas

Runtime, data, and delivery in motion.

Languages, frameworks, infrastructure, and operational tooling that combine well in real product work, from APIs to lower-level runtimes.

Trajectory

Education & experience, shaped as one track.

A read closer to real trajectory: education as foundation, experience as a sequence of chapters with growing operational responsibility.

Operational track

Experience

Where the trajectory gains weight: product, operations, internal systems, and delivery accountability.

Lead chapter

Founder & Lead Software Engineer

Founded and led backend-first product work spanning architecture, API design, domain modelling, and production-grade delivery.

Structured services and asynchronous workflows around explicit contracts, idempotency, observability, and change safety, with long-term maintainability as a first-order concern.

Scope: Architecture, APIs, domain modelling, and production infrastructure
Operating model: Explicit contracts, observability, idempotency, and safe iterative delivery

Twitch

Digital Community Manager

Led community operations and audience growth for a Twitch project, treating retention, reach, and engagement as operational signals rather than vanity metrics.

Built moderation, publishing cadence, and communication workflows with a stronger emphasis on consistency, responsiveness, and measurable audience behaviour.

Via Flix

Head of Digital Marketing & Marketplace Operations

Led digital operations and the internal systems layer behind more than BRL 10 million in revenue over 12 months and 100,000+ marketplace orders across Amazon, Shopee, and Mercado Livre.

Designed tooling, automations, dashboards, and data pipelines that reduced operational effort by 35%, saved roughly 10 hours per week, and made commercial execution materially more predictable.

Commercial scale: Operation supported eight-figure annualised revenue and six-figure order volume
Channel growth: Amazon scaled from roughly BRL 5K to BRL 150K per month; Shopee reached seven figures annually
