Recently found Ali from Upwork.
We had a work related to a fitness app in iOS.
He genuinely designed our app in a very short time.
He is very skilled, professional and a kind person to work with.
Definitely recommending Ali to anyone who want to develop a full-scale iOS app or design.
Thanks again!

Senior Full-Stack Developer for Privacy-First Mobile Intelligence MVP
Ali Mert delivered an outstanding architecture sprint for my platform, HuntLine IQ, and exceeded expectations in both depth and professionalism from start to finish.
From the beginning, Ali demonstrated a strong ability to take a complex, highly nuanced product vision and translate it into a structured, build-ready system. My project is not a simple application—it involves geospatial logic, privacy-first data aggregation, configurable delay systems, entitlement-based access, and multi-layered validation rules. Ali not only understood these requirements quickly, but he also challenged assumptions where needed and helped refine several core concepts to make the system more scalable and realistic to implement.
The final architecture deliverables were extremely thorough. He produced a comprehensive set of documents (50+ pages) covering database schema design, system architecture, configuration layers, zone logic, and signal processing workflows. What stood out most was how everything connected—this wasn’t just a collection of diagrams or ideas, but a cohesive system where each component clearly mapped back to the product requirements.
One of the most valuable aspects of working with Ali was his focus on configurability and long-term flexibility. Instead of hardcoding decisions into the system, he designed key elements—such as zone thresholds, delay matrices, and independence rules—to be configurable. This approach gives me the ability to adjust and evolve the platform over time without needing to rebuild core systems, which is critical for a product that will scale across multiple regions and user densities.
Communication throughout the project was excellent. Ali was responsive, clear, and very organized in how he presented information. He consistently referenced specific sections of the documentation when answering questions, which made it easy to track decisions and maintain alignment. He also provided thoughtful explanations when there were trade-offs or alternative approaches, allowing me to make informed decisions as the product owner.
Another thing I appreciated was his ability to identify gaps or inconsistencies in the original product documentation. Rather than blindly implementing what was written, he flagged areas that needed clarification and proposed solutions. This level of attention is exactly what you want in an early-stage architecture phase, where mistakes or oversights can become very costly later in development.
Ali also showed a strong understanding of modern tooling and best practices. His recommendations around infrastructure—such as using PostgreSQL with row-level security, Supabase for backend services, and a modular configuration-driven design—were well aligned with building a secure, scalable, and maintainable system. He clearly thinks beyond just “getting something working” and instead focuses on building a solid foundation that can support growth.
From a project management standpoint, the milestone structure was clean and well executed. Each phase delivered tangible progress, and there was always clear forward momentum. He stayed on schedule, communicated proactively, and ensured that each deliverable met a high standard before moving on.
Overall, this architecture sprint has given me a high level of confidence moving into development. Instead of starting from a rough concept, I now have a detailed, well-structured blueprint that developers can actually build from. That is a huge difference, and it’s a direct result of Ali’s work.
I would highly recommend Ali to anyone looking for a serious, detail-oriented architect who can take a complex idea and turn it into a scalable, production-ready system design. I would absolutely work with him again on future phases of this project.
