About

Flutter Engineer with a strong focus on reliability, delivery, and long-term leverage. I enjoy turning ideas into production-ready mobile products — backed by solid architecture, CI/CD, and thoughtful engineering decisions. In my spare time, I contribute to open source and share what I learn along the way. Happy to connect on Flutter, mobile engineering, and building products that last.

Software Engineer

Jan 2025 – Present · 1 yr 2 mos · Remote

Flutter Engineer working on the Heartbeat App, with a strong focus on reliability, scalability, and cross-team impact in a fast-growing CleanTech environment.
Featured achievements:
Drove customer trust and product transparency by leading the Customer Journey tab implementation, delivering 43+ issues in 3 months with 100% test coverage while aligning complex requirements across multiple teams.
Enabled scalable international expansion by introducing a contract abstraction that decouples app features from market-specific contracts; later moved this abstraction to the TypeScript/Nest.js backend to support additional clients and reduce dependency on mobile release cycles.
Shifted the team toward test-driven reliability by driving automated testing adoption (AI-assisted test rules, documentation, coverage tooling, and cultural reinforcement), increasing Heartbeat App test coverage from 9.43% to 74%+ on 600.000+ lines of code within less than a year.
Improved delivery speed, production resilience, and engineering leverage by implementing code push (reducing MTTR from 1–2 days to under 1 hour), joining the on-call rotation, and championing AI-assisted development through a company-wide Slack community (84+ engineers), bi-weekly knowledge-sharing sessions, and a proof of concept to enable the introduction of Cursor at scale.
