Senior Android Developer

Act as the main quality gate for a team of 8 Android engineers — drive code reviews ensuring
architectural consistency and code quality

Mentor mid/junior developers on feature design and implementation, guiding architectural decisions and
improving code quality

Built CI/CD pipeline (GitLab CI) with automated builds, Firebase App Distribution, and Telegram, Teams
notifications — replacing manual processes and improving release visibility

Introduced centralized API call handling layer, standardizing network interaction and reducing
boilerplate across ViewModels

Improved networking layer by redesigning interceptors and standardizing request/response handling,
increasing stability and debuggability

Drove 112% growth in completed orders by owning and delivering the NewEstimate flow — built with
layered Clean Architecture and complex state-driven logic.

Led the end-to-end rebuild of the Request Sketch flow — the app’s highest-selling product. Identified
and resolved 15+ API-level inconsistencies through intensive cross-team collaboration.

Drove UX/UI improvements in close partnership with design, iOS, and product — standardizing
component behavior and reducing development time through shared layout logic.

Initiated and led data layer refactoring across a legacy codebase. Documented scalable patterns in
Confluence with structural guidelines adopted in later features.

Owned Android anti-fraud features as the sole engineer on the mobile team — integrated external
SDKs, implemented root detection and API key protection to secure cashless payment flows.

Prevented $100K+ in monthly fraud losses by identifying suspicious behavior patterns and hardening
abuse vectors — in close collaboration with backend and security teams.

Developed localized payment flows for Brazil, Australia, and the US — including bank account creation
and billing logic. Provided ongoing support for Google Pay integration as part of broader payment
infrastructure work.

Sole Android developer and project lead for an internal SDK powering registration, onboarding, and
secure authentication across multiple banking apps; built as a modular and reusable solution later
adopted by other teams.

Integrated third-party SDKs for facial recognition and document scanning, enabling fast and secure
remote registration via camera input.

Migrated legacy codebase to Clean Architecture, significantly improving testability and long-term
maintainability.

Delivered real-time onboarding via WebSocket-driven validation, and implemented secure biometric login,
PIN, and recovery flows.

Rebuilt the Payments module (utility bills, services, transfers), ensuring reliability despite undocumented
legacy flows

Developed registration and authentication system from scratch (PIN, facial recognition, password
recovery)

Maintained and stabilized legacy features during release cycles — resolving UI regressions and ensuring
production readiness.

Built and maintained full-cycle CI/CD pipelines using Bamboo, Docker, and Ansible — writing Bash,
PowerShell, and YAML scripts for builds, environment setup, deployments, and automated testing.

Reduced smoke test execution time from 4 days to 1 hour via parallel execution (Selenoid)

Mentored junior QA engineers and standardized testing processes

Presented solutions to senior management, secured infrastructure budget, and aligned cross-team test
priorities through direct collaboration with dev and QA teams.
