Cover image for Since January, I haven’t taken
Since January, I haven’t taken on a new contract not because I’m not looking, but because I’m focused on finding the right projects. I’m a Senior Mobile Engineer working with native iOS (Swift), Android (Kotlin) and cross-platform(React Native, Flutter) when needed, building scalable, production-ready apps with clean architecture. I’ve worked on real-world apps with complex flows, offline support, and long-term maintainability in mind. I’m currently open to new opportunities ideally long-term collaborations with startups or companies building serious mobile products. Attached is one of my current ongoing projects, Valto, an offline-first budget management app I’m building. If you’re working on something interesting or know a team that needs strong mobile expertise, I’d be glad to connect. Thanks!

Cover image for Title: mBizzi — Mobile Business Management
Title: mBizzi — Mobile Business Management Platform Short description: Designed and developed a mobile-first business platform focused on simplifying day-to-day business operations through an intuitive, reliable, and scalable application experience. Our contribution: Mobile application architecture, native app development, API integration, authentication, data management, reusable UI components, performance optimization, testing, release engineering, and ongoing product improvements. Services/tags: Mobile Development · Android · iOS · API Integration · Product Engineering · Backend Development · UI/UX Case-study graphic structure To match the PixiKids / SEOForge / Lomo graphics, use: Header mBizzi Mobile Business Management Platform One-liner A mobile-first platform designed to simplify business operations and deliver a fast, intuitive experience for users on the go. The Challenge Build a reliable mobile product that brings essential business workflows into one streamlined experience while maintaining performance, usability, and scalability as the platform grows. The Solution We engineered mBizzi around a modular mobile architecture with secure API integrations, structured data management, reusable application components, and an interface optimized for everyday business workflows. Our Role Mobile application architecture Native mobile development Backend & REST API integration Authentication & user management Data architecture and synchronization UI implementation and reusable components Performance optimization Testing, debugging and release engineering Core Features Business workflow management Secure user authentication Account/profile management Real-time data synchronization Business dashboards Search and structured navigation Notifications and alerts Responsive mobile experience Technical Architecture Use a simple visual: Mobile App → API Gateway → Backend Services → Database with Authentication + Notifications/Cloud Services around the backend. Results & Impact For this section, don't invent numbers. If you have verified mBizzi metrics—downloads, rating, users, transaction volume, performance improvement, etc.—give them to me and we can make this section quantitative. Otherwise use defensible qualitative outcomes: Mobile-First — Business workflows available anywhere Scalable — Modular architecture designed for growth Reliable — Structured API and data integration Optimized — Fast and responsive mobile experience Maintainable — Reusable components and clean architecture And visually, I'd make the mBizzi case study different enough from PixiKids to show range while retaining the same layout system. Then your initial Contra portfolio becomes: PixiKids → parental-control/mobile engineering SEOForge → B2B SaaS Lomo → AI/social/creative platform mBizzi → business/productivity mobile engineering That's a solid four-project foundation for CSP.

Cover image for Title: Lomo — AI-Powered Mobile Creative
Title: Lomo — AI-Powered Mobile Creative & Social Platform I would use Lomo, rather than locking the Contra case study to the old “Lomo Graph” branding, since the product is evolving into Lomo Live. Short description: Designed and engineered a native mobile platform combining visual creation, AI-assisted editing, cloud media management and social discovery, with an architecture designed to evolve into community, messaging and real-time live experiences. Our contribution: Product architecture, native iOS/Android engineering, media workflows, backend and cloud integrations, authentication, performance optimization, CI/CD, testing and scalable platform design. Services/tags: Mobile Development · Product Engineering · AI · iOS · Android · Backend Development · Cloud This one is strategically valuable because it's your own product. You aren't merely saying CSP can engineer ambitious products—you can show one being built internally.

Cover image for Title: PixiKids — iOS & Android
Title: PixiKids — iOS & Android Parental Control Platform Short description: Designed and engineered a cross-platform parental control solution for families, combining screen-time management, application restrictions, activity insights, location features, notifications, and secure cloud synchronization. Our contribution: Native iOS and Android engineering, application architecture, backend/API integration, database and cloud design, performance optimization, testing, CI/CD, and store-release engineering. Services/tags: Mobile Development · iOS · Android · SwiftUI · Kotlin · Firebase · Backend Development The visual is excellent for Contra because it immediately communicates real product complexity + mobile engineering.

Cover image for Title: SEOForge — Multi-Tenant SEO SaaS
Title: SEOForge — Multi-Tenant SEO SaaS Platform Short description: Built a scalable SaaS platform for agencies and businesses to centralize SEO auditing, keyword tracking, backlink and competitor analysis, Search Console data, reporting, and multi-project management. Our contribution: SaaS architecture, React/TypeScript frontend, Node.js backend, PostgreSQL data layer, third-party SEO/API integrations, authentication and roles, Redis caching, Docker/cloud deployment, and CI/CD. Services/tags: SaaS Development · Web Development · React · TypeScript · Node.js · PostgreSQL · AWS This should probably become your flagship SaaS case study. One caution: your graphic contains specific impact claims such as +200% user growth, +35% client traffic, -60% reporting time, 150 agencies and 4.8/5. Only publish those as factual outcomes if you can substantiate them. Otherwise I'd remove/replace those claims before treating the graphic as a formal case study.
