Engineering beyond the screen.

Marlen builds complex products across full-stack Flutter delivery, Android, iOS, Web, macOS, Windows, Linux, Serverpod API development, native integrations, offline-first data, GIS, BLE-connected hardware, camera and media workflows, documents, payments, product analytics, and cloud services.

That technical ownership is paired with practical delivery habits: discovery, requirement clarification, project planning, sprint estimation, ETA reporting, risk management, demos, feedback capture, analytics-event alignment, follow-ups, and release coordination.

Client-facing delivery

Capabilities shown through delivery examples.

Discovery to scope

Clarifies client requirements, maps business needs to mobile scope, and turns decisions into sprint-ready stories and acceptance criteria.

Supported by senior delivery work on Perfecta, Pegasus, Eurogrip, and OPTX case studies.

Planning and ETA communication

Prepares milestones, estimates, sprint plans, and delivery ETAs while communicating progress, dependencies, blockers, and revised timelines.

Experience data includes sprint planning, story estimation, API planning, and stakeholder-ready release coordination.

Client demos and follow-ups

Runs demos, captures feedback, tracks action items, and keeps follow-ups structured so engineering decisions stay connected to product goals.

Case-study delivery sections document demos, feedback handling, follow-up actions, and release-readiness support.

Cross-functional release delivery

Coordinates mobile work across design, backend, QA, DevOps, and product teams through release planning, app-store submissions, and post-release monitoring.

Public projects span Flutter, native Android, SwiftUI, Serverpod APIs, product analytics, IoT hardware, offline-first apps, and real-time dashboards.
