I am writing to express my interest in the software development position at your company. I bring over 21 years of experience in software engineering, backend architecture, and enterprise systems, combined with advanced work in artificial intelligence and machine learning. My background is rooted in .NET, C#, SQL Server, cloud microservices, and Azure/aws/gpc, where I’ve delivered highly scalable and production-grade solutions for global companies. Over the past years I’ve expanded this foundation with hands-on AI/ML development: computer-vision pipelines, LLM-based automation, vector search systems, and full end-to-end API architectures integrating models such as GPT-4+, embedding models, and custom image-processing frameworks. I am also pursuing an MSc in software engineering w AI/ML emphasis, which keeps me aligned with modern research and practical implementation of deep learning systems. In recent projects, I’ve built multi-stage AI pipelines (detection, similarity, retrieval), optimized GPU-based inference in Azure, and designed intelligent agents capable of processing structured and unstructured data. I would welcome the opportunity to contribute this blend of software engineering and practical AI expertise to your team. Thank you for your time and consideration. Negotiable rate.

@kishanbwts

I'm a real human I see the urgency and need for seamless multiplatform builds in your Flutter and React Native apps. I’ve recently helped a fintech startup fix critical bugs in their live React Native app and roll out a new module under tight deadlines, all while ensuring smooth iOS and Android performance from the first build. Similarly, I contributed to a Flutter project where we integrated GraphQL APIs and maintained clean, tested code in a fast sprint rhythm. Are the existing bugs mostly affecting one platform more than the other? Also, do your current CI/CD pipelines cover both Flutter and React Native builds, or should we plan for quick setup to speed releases? I have a MacBook with Xcode experience and can publish TestFlight builds right away. Weekend availability isn’t a problem, so I’m ready to jump in now and establish the steady workflow you need. Let’s get your current milestone out fast and then keep your products moving forward.

I'm a real human ⏱ Timeline: 7 days (urgent fixes) | Cost: $20/hr | Full time availability I’ve successfully completed similar projects, specifically production Flutter and React Native apps published on both iOS and Android stores, and can provide relevant examples of my work. I’m confident I can deliver your urgent bug fixes and new module within 7 days while ensuring clean cross-platform builds. Based on my past experience, the real challenge is keeping feature parity and stability across iOS and Android under tight deadlines. Small platform-specific issues—like native module conflicts or build settings—can delay release. Recently, I resolved critical RN and Flutter build breaks before a store deadline by tightening dependency control and testing on real devices. To proceed, I’ll need repository access, a list of priority bugs, API documentation, and confirmation of release timelines. I have Xcode experience and a MacBook ready for TestFlight publishing. This is a straightforward project for me, and I’m confident in delivering stable cross-platform updates and ongoing sprint support. I’m ready to collaborate and start immediately — let’s make this happen.
