Overview
mirantes.io is the main product of Mirantes Technologies: professionals create a profile, find job opportunities, apply and follow their applications; companies publish vacancies, recruit and manage employees. It runs as a web application with companion mobile apps.
Problem
The platform serves users in Angola and other African countries on mixed devices and low-bandwidth connections. The frontend had to render fast, keep data fresh without heavy re-fetching and give job seekers and recruiters reliable forms and flows.
Role
I built and maintained the Next.js/TypeScript web application and led the frontend team's technical work: code review, technical guidance and consistency across the codebase.
I owned platform performance on the frontend — rendering strategy, caching and production debugging. Backend work in this period is not claimed.
Architecture
- Next.js with TypeScript, using SSR/SSG rendering strategies per page type and lazy loading to keep first render fast.
- Data fetching and caching with React Query so lists, applications and profile data stay consistent across the app.
- Forms and validation flows for profiles, applications and recruiter workflows, styled with Tailwind CSS.
Technical decisions
- Rendering strategy per page
- Public and SEO-relevant pages use server rendering or static generation; authenticated, data-heavy views are client-rendered with cached queries, which balanced speed and freshness on slow connections.
- Caching as the performance lever
- Rather than optimising individual components, the biggest wins came from caching data retrieval and avoiding redundant requests across navigation.
- Consistency through review
- As team lead the priority was a coherent codebase: shared patterns for forms, data access and layout enforced through code review.

Engineering challenges
- Keeping the application fast on low-bandwidth connections while the product grew in scope.
- Coordinating a frontend team on one codebase while shipping continuously.
Outcome
The platform is live at mirantes.io and remains the core product of Mirantes Technologies; this engagement ended in February 2024 when my role moved towards technical coordination and, later, Mirantes for Creators.
What I learned
- Performance on a real user base is mostly data-flow discipline, not micro-optimisation.
- Leading a frontend team is largely about making the right pattern the easy pattern.
