Signeesti Secure Digital Contracting Ecosystem for the Nordic Market
Role / Expertise:
Lead Flutter Engineer & Architect
Signeesti is a premium digital signature and contract lifecycle management platform built specifically for high-trust environments (Estonia and the Nordic region).
I architected and developed the complete end-to-end user experience, transforming a complex legal workflow into a seamless mobile application. My work focused on creating a production-ready system where technical performance directly supports legal compliance.
Core Architectural Features (As visualized in the 3D ecosystem map):
Scalable Architecture: Implemented a robust architecture (using Bloc and Provider) to handle asynchronous contract workflows, from initial drafting to final e-stamping.
Rest API & AI Integration: Developed real-time connections to secure legal APIs and integrated AI to analyze engagement metrics and predict contract finalization times (visualized via the Audit Trail chart).
Data Persistence & Firebase: Utilized Firebase for real-time state synchronization across devices and implemented a secure local database (SQLite/Hive) for "offline-first" legal document access.
Legal & Security Compliance: Managed specialized integrations for GDPR compliance (as marked in the data visualization) and implemented secure verification methods (ID-Card and E-Stamps) with full pixel-perfect UI precision.

Board Vibes: The Future of AI-Driven Learning
The Problem:
Traditional secondary education in Pakistan often lacks accessible, high quality digital resources and personalized tutoring. Students struggle with outdated study materials and a lack of real time feedback during exam preparation.
What I Built: Board Vibes is a complete Flutter study platform I designed, developed, and published entirely on my own. It includes offline MCQ quizzes, a Gemini AI chatbot that answers exam questions in context, downloadable PDF books, multi profile switching for siblings sharing one device, study streaks, and AdMob monetization.
The Result: Live on the Google Play Store (https://play.google.com/store/apps/details?id=com.areej.board_vibes) under my own developer account. Real downloads, real users, real ad revenue not a demo, not a side project. A shipped product I own end to end.
What this proves for you as a client: I don't just write code. I take an idea from zero, make all the product decisions, handle every technical challenge, and deliver something people actually use.
