Top freelance Langchain developers available to hire
I have a great passion for solving problems and can help people with various programming languages, databases, information systems, software related projects.
Full-Stack Web Developer with 10+ years delivering production web applications for product teams and client-facing platforms. Strong frontend experience with React and TypeScript, paired with backend development in Python for API-driven systems and data-heavy workflows. Experienced in integrating third-party services, designing REST APIs, and building reliable data-driven platforms. Comfortable deploying and operating applications on AWS, working with containerized environments, CI/CD pipelines, and cloud infrastructure to ensure scalable and maintainable production systems. Proven track record of shipping maintainable features in remote teams and improving reliability through clean code, automated validation, and pragmatic DevOps practices.
I am a Senior Software Engineer with 7+ years of experience delivering scalable web, mobile, and AI solutions through technical consultancy and staff augmentation. I have a proven track record of architecting and shipping applications for diverse industries including FinTech, HealthTech, and enterprise SaaS. My expertise spans modern JavaScript ecosystems (Node.js, Next.js, React Native), Python (AI/LLMs, RAG pipelines), and robust backend infrastructure (Supabase, Firebase, AWS, SQL/C#). I thrive in high-velocity, autonomous environments where I can take full ownership of the tech stack, whether that means rescuing a legacy system or building a zero-to-one MVP, I want to mentor because Ive realized my biggest impact comes from helping other engineers stop just writing code and start thinking like system architects who can solve real-world problems.
I **define the architecture**. For 21 years, I've been the person CTOs and lead developers call when systems fail under load, migrations are at risk, or AI integration needs to work right the first time.
With expertise in **C#, .NET, Blazor, ASP.NET Core, SQL, Python,** and production AI agents (**Semantic Kernel, LangGraph, custom tool-calling**), I design systems where performance, reliability, and intelligent automation aren't optional—they're the baseline.
I've shipped AI to **production** — not to a Jupyter notebook. I'm the creator of **FreeAIVoice** — a live AI voice platform with AI Voice Generation, Voice Cloning, and Speech-to-Text across **30+ spoken languages** and a developer API. I provided production systems for The New York Times.

**Here's where I'm most useful to you:**
- **The AI Integration Trap** — You've been asked to add AI to your existing .NET system but don't know whether to use *Semantic Kernel*, raw OpenAI APIs, or a Python sidecar. I've made that decision dozens of times. I'll make it faster and safer for you.
- **The Blazor Bottleneck** — Your Blazor app is slow, state management is tangled, and you're unsure if you chose *Server or WASM* incorrectly. I can diagnose what went wrong and map a clean path forward — often in a single session.
- **The Legacy Modernization Cliff** — You have a 10-year-old .NET system that needs AI or modern tooling but wasn't designed for it. I specialize in *incremental refactoring paths* that don't require a full rewrite and don't break what's already working.
---
**What I Do Best:**
- **Software Architecture & System Design** — scalable, maintainable systems from greenfield to enterprise
- **AI Agent Development** — production-grade agents with Semantic Kernel, LangGraph & AutoGen — *not demos*
- **Blazor & ASP.NET Core** — Server, WASM, hybrid — full-cycle development and performance tuning
- **Python & AI Automation** — RAG pipelines, workflow automation, voice AI, LLM integrations
- **Legacy .NET Modernization** — refactoring strategy, migration paths, incremental upgrades
- **Architecture Audits** — identifying structural risk before it becomes a production incident, not after
- **Debugging Complex Systems** — when the stack trace doesn't tell the whole story
**If any of this sounds like your current situation — DM me. I respond to every message.**
