What our clients say about working with DecryptCode on mobile and AI projects
DecryptCode Team contributed to the successful launches of our FleetUp.com's HOS App and FMS App in the United States. Over the course of 3+ years, as an engineering director, I can count on them to deliver new features on schedule with excellent quality.
DecryptCode stepped into our in-flight Kotlin mobile app project, ramped-up quickly to take on all of the development for a series of releases to Google Play. Bravely took on arcane features and delivered them to the product.
The DecryptCode team is a true professional. Throughout this project, there has been clear communication and expectations and on-time delivery of each milestone. Comprehensive experience in complex mobile apps.
Great company. Great communication, great code, and great flexibility. Quality of work is amazing. Similar or better than the highest quality of developers I have ever worked with.
Highly recommend, working on multiple projects with them!
We had an awesome experience with Decryptcode team. They developed an enterprise app for iPad and Android tablets for managing gas stations — it was beyond our company's expectation. The project was complex with integration of Bluetooth-based scanners. Amazing job!

Frequently Asked Questions
What services does DecryptCode INC offer?
We offer mobile app development (iOS, Android, React Native), AI and machine learning solutions (RAG pipelines, agentic AI workflows, conversational AI, ML model development), custom software development, data and LLM pipeline engineering, cloud-native infrastructure (AWS, GCP, Azure), and IoT integration. We serve clients across the United States from our White Plains, New York office.
What is a RAG pipeline and how can it help my business?
A Retrieval-Augmented Generation (RAG) pipeline connects large language models to your proprietary business data. It enables employees to ask questions in natural language and receive accurate, citation-backed answers grounded in your documents, knowledge base, or internal systems. We build production-grade RAG solutions using LangChain, vector databases like Pinecone, and hybrid search strategies.
How much does it cost to develop a mobile app?
Mobile app development costs vary based on complexity, platform (iOS, Android, or cross-platform), features, and integrations. Simple apps may start at $25,000–$50,000, while complex enterprise apps with AI features, real-time data, and backend systems typically range from $75,000 to $250,000+. Contact us for a detailed project estimate tailored to your requirements.
What AI technologies does DecryptCode work with?
We work with OpenAI GPT models, Claude (Anthropic), LangChain, TensorFlow, PyTorch, AWS SageMaker, Google Vertex AI, Pinecone, CrewAI, AutoGen, and more. We specialize in RAG systems, agentic AI workflows, conversational AI, custom ML model training, NLP, computer vision, and edge AI deployment.
Where is DecryptCode located? Do you work with remote clients?
DecryptCode INC is headquartered in White Plains, New York (10606). We serve clients across the entire United States and work with remote teams globally. Our Agile development process includes regular standups, demos, and transparent progress tracking for seamless collaboration regardless of location.
How long does it take to develop an AI solution?
AI development timelines depend on the project scope. A basic chatbot or RAG prototype can be delivered in 4–6 weeks. A full production RAG system or agentic AI workflow typically takes 8–16 weeks. Complex ML pipelines with custom model training, evaluation harnesses, and MLOps infrastructure may require 12–24 weeks. We follow an Agile process with incremental deliveries.
