Lucas Agliardi
Tech Lead & Software Architect
Florianópolis, SC — Brazil
Scalable architecture, technical leadership and a focus on results. Experience with SaaS platforms, high-scale e-commerce and cross-functional teams.
14+ years across architecture, leadership and delivery. Experience with teams of up to 35 people, building multi-tenant SaaS products and highly complex projects for national and international brands.
I work between architecture decisions and code. I set standards, do in-depth code reviews, and go hands-on when the risk is high. Focused on performance, quality and real business impact.

Cases & Results
Technical decisions with direct business impact.
Manux — Headless E-commerce Platform
Multi-tenant headless SaaS platform for e-commerce. Architecture based on DDD and Clean Architecture, with SSR, REST/GraphQL integrations, an in-house payment method and connections to 20+ platforms. Powers projects that are benchmarks in Latin America, including the continent's largest PPE store.
From a monolithic template to 12 versioned Nuxt Layers
I broke a monolithic storefront template into 12 Nuxt Layers published as independent repositories (core, catalog, checkout, account, CMS, chrome, SEO, analytics, modals, routes, types and docs). Each client store became a thin theme shell that inherits the layers by SHA pinned in its own lockfile, with a local toggle for development. Components and composables are shared across every store, with SSR caching in Nitro and LCP preload computed per breakpoint.
Headless migration without rewriting checkout
The same architectural decision applied across two different platforms: the storefront goes headless in Nuxt, but account and checkout stay on the original platform. On VTEX, the account and checkout layers are deliberately not extended, and the two runtimes talk through an orderForm cookie jar and pixel-based session sync. On Nuvemshop, the purchase and account routes are handed back to the platform via reverse proxy on the same domain, with a Nitro BFF signing all communication. It removes the biggest risk of a headless migration: rewriting the logged-in area.
From 419 to 24 JS requests on a high-scale store
I rebuilt the chunk graph and hydration strategy of a large PPE operation without touching business rules. Manual chunking by group, inlined styles, removal of unnecessary preload and prefetch, on-demand hydration for blocks below the fold, a disk image cache that survives deploys, and an LCP preload mirroring the srcset per breakpoint. The store also serves an agent card and llms.txt, making it readable to AI agents.
Enrolment portal with a WhatsApp bot the school edits itself
An enrolment reservation portal integrated with the academic CRM and the visit scheduler, with WhatsApp support. The core decision was to model the entire conversation tree as versioned data, validated at the edge and editable by the school office through its own panel: changing the bot stopped being an engineer's deploy and became a task for the people answering, with a kill switch that reverts to the previous behaviour without a rollback. Message sending was moved off the critical path so families never wait on the queue.
Regulated prize draws, auditable end to end
Two nationwide promotional campaigns drawn against the Brazilian Federal Lottery. I modelled the lucky number as a federal ticket — a universe of 10 million across 100 series of 100,000 orders — with deterministic hash-based assignment, a uniqueness table, an audit trail and export in the layout required by the regulator. Every write goes through a server-side BFF that revalidates the credential on each request, backed by row-level security in the database.
Technical leadership of 60+ projects with a 35-person team
Technical leadership of a team of more than 35 professionals, driving architecture and delivery of complex e-commerce and SaaS projects at national scale. Served major brands such as Calvin Klein, Xiaomi and Lebes. Built reusable modular stacks focused on performance and technical standardization.
PageSpeed 90+ methodology applied to 500+ projects
A web performance methodology that became the standard across every project under my leadership. Combining SSR, smart lazy loading, asset optimization, Core Web Vitals and technical SEO strategies. Applied to more than 500 projects across 20+ different platforms, with consistent results of tripling revenue within 6 months.

How I lead
Clear standards and technical governance
I define architecture, guidelines, acceptance criteria and the definition of done before any sprint. I structure modular, reusable stacks. The team knows exactly what is expected and why.
In-depth code review and mentoring
Every review is a chance to teach. I pair program on critical decisions, set PR standards and equip the team to make good calls on their own.
Hands-on when the risk is high
On critical components, complex integrations or architectural decisions, I get into the code. I lead by example and by delivery, not just by title.
Alignment between product and engineering
I translate technical trade-offs into business language. I take part in product decisions, prioritization and technical roadmap with a focus on direct impact on business metrics.

Questions recruiters usually ask
-
I lead through three levers: (1) clear standards — architecture, guidelines, definition of done and reusable modular stacks; (2) in-depth code review and constant mentoring, where every PR is a chance to teach; (3) alignment with product on technical trade-offs to guarantee impact on business metrics. When the risk is high, I get into the code and lead by example.
-
I have hands-on experience with DDD, Clean Architecture, microservices, REST/GraphQL, and headless and multi-tenant architectures. I helped build Manux — a headless SaaS platform connected to 20+ e-commerce platforms, with its own payment method, which today powers benchmark projects in Latin America. I define non-functional criteria, run proofs of concept and make architectural decisions focused on scalability and performance.
-
Yes. My main specialty is front-end and web architecture, but I work fullstack when needed. On the backend I work with Node.js/TypeScript and PHP/Laravel, with experience in Python, Ruby and .NET, as well as MySQL, PostgreSQL, SQLite, Supabase, payment integrations (Pagame, Mercado Pago, PagPow!) and internal/external APIs. I also have strong experience with GenAI — integrating OpenAI and Gemini, building agents and orchestrating LLMs.
