🎯 Who is this job for?

This position is well-suited for an experienced frontend or full-stack engineer who wants to lead a distributed team while still contributing hands-on, driving React-based architecture, delivery quality, and engineering excellence; someone who thrives in ownership, cross-functional collaboration, and guiding technical decisions that support a fast-scaling fintech environment.

💬 Potential Interview Questions

How do you balance leadership responsibilities with hands-on technical work?
I block focused time for coding each sprint, but reserve mornings for standups, 1:1s, and unblocking the team. I delegate implementation details, own architecture and critical paths, and use code reviews and pairing to stay close to the code without becoming a bottleneck.
Describe your experience leading cross-functional, distributed teams.
I’ve led 7–10 person squads (FE, BE, QA, DevOps) across multiple time zones: set clear sprint goals, defined ownership per domain, used async updates (Slack, docs) plus structured ceremonies, and kept tight feedback loops via regular 1:1s and clear expectations on quality and communication.
How do you ensure consistent high-quality sprint delivery?
Start with well-groomed tickets and clear acceptance criteria, estimate as a team, minimize WIP, and track progress via daily standups and simple metrics (throughput, carry-over, defects). Quality is enforced with code review, CI checks, definition of done, and fast feedback from QA.
What is your experience with React, TypeScript, and state management?
7+ years building SPAs with React + TypeScript: complex forms, dashboards, role-based UIs. For state, I’ve used Redux, MobX, Zustand, and React Query, choosing per use case: server vs client state, complexity, and team familiarity.
Can you describe a micro-frontend architecture you implemented or worked with?
I’ve used Webpack Module Federation to split a large frontend into domain-based micro-frontends (checkout, admin, analytics), with a shell app hosting remotes. We shared core libraries (design system, auth, i18n), ensured independent deployment, and aligned on versioning and routing contracts.
How do you handle legacy code refactoring while still delivering features?
I apply the “strangler fig” pattern: isolate legacy parts behind clear interfaces, refactor opportunistically when touching code, and plan small, incremental improvements per sprint. I avoid big rewrites; instead, I combine refactoring with feature work and track tech debt as visible backlog items.
What is your experience with Java and backend collaboration?
I’ve worked on full-stack features using Java + Spring/REST, reading and refactoring existing services, designing contracts with backend, and ensuring FE–BE integration via OpenAPI/Swagger, contract tests, and shared DTOs. Even when focused on FE, I’m comfortable reading Java code and proposing changes.
How do you use CI/CD and DevOps tooling to support your team?
I’ve set up pipelines with GitLab CI and CircleCI: linting, tests, builds, security checks, and automated deployments in Dockerized environments. I encourage feature branches + merge requests, use preview environments for product/design, and keep pipelines fast so they’re trusted and not bypassed.
How do you handle conflicts and underperformance within the team?
First I listen: understand perspectives 1:1, clarify expectations and facts, then align on shared goals. For underperformance, I agree on a concrete improvement plan with clear milestones, support (mentoring, pair programming), and regular check-ins. If needed, I escalate transparently.
Why are you interested in leading a frontend/full stack team in a fintech company?
I enjoy complex, high-stakes domains where quality and security really matter, and fintech fits that perfectly. This role combines what I like most: leading a strong team, shaping modern React/TypeScript architecture (micro-frontends, CI/CD), and delivering user-facing features that directly support business growth.
