Top freelance Fastapi developers available to hire
Seasoned Web Developer and Blockchain enthusiast with a proven track record in the IT and services industry. Expertise in Research, PHP, HTML, JavaScript, and Blockchain development, including Smart Contracts. Skilled in automation, application testing, and cybersecurity analysis for web and mobile apps.
I'm a Highly accomplished and results-oriented Engineer with extensive experience in **Full-stack Development, Artificial Intelligence (AI), Cloud Computing, and MLOps/AI** Pipelines
I help engineers here—especially those early in their journey—build real-world skills through code reviews, system design, and project guidance. My approach is grounded in clarity, scalability, and long-term growth.
I am currently employed as a frontend lead at Cyberspace. I’m hands on in all stages of software development cycle, from planning and design to testing and deployment.
Jude is passionate about algorithms analysis, bug fixes, brainstorming ideas, integrating and building new systems
I’m a Senior Software Engineer with 10+ years of experience building scalable full-stack, SaaS, and AI-powered applications. My core stack includes JavaScript/TypeScript, React, Node.js, Python, PostgreSQL, and AWS, with strong experience designing cloud-native and microservices-based systems.
In recent years, I’ve focused heavily on AI-driven platforms and intelligent automation. I recently architected an enterprise AI copilot platform using Python (FastAPI), Node.js, LangChain, Weaviate, and multiple LLM providers. The platform supports conversational AI, RAG-based document retrieval, realtime streaming responses, and voice interaction using speech-to-text and text-to-speech services.
I’ve also worked on AI-driven multimedia systems involving voice-enabled AI avatars, realtime conversational interfaces, media upload pipelines, and AI-assisted content workflows. My experience includes practical use of FFmpeg for media compression, streaming optimization, format conversion, and multimedia processing workflows, alongside integrations with OpenAI and ElevenLabs APIs for voice and conversational AI experiences.
Previously, I developed AI assistants and automation tools including a LangChain-powered ecommerce support chatbot and a voice-enabled AI assistant using Flask, ChromaDB, and OpenAI. These systems combined LLM reasoning with contextual retrieval pipelines to deliver accurate, production-ready AI interactions.
Beyond AI systems, I’ve built and scaled multiple production SaaS platforms across fintech, ecommerce, HR, e-voting, and enterprise operations. Notable projects include FlexiCoop (multi-tenant fintech SaaS), Fivage cloud storage platform, Scavenge ecommerce systems, and cross-platform offline-first POS applications built with Electron.
On the infrastructure side, I regularly deploy and scale applications using AWS services including EC2, RDS, S3, CloudFront, Route53, IAM, and CI/CD pipelines through GitHub Actions and AWS Amplify.
I also actively leverage AI-assisted development tools such as Cursor, GitHub Copilot, and ChatGPT to accelerate engineering workflows, refactor legacy systems, and rapidly prototype scalable features.
Overall, I enjoy building AI-enabled products and scalable systems that bridge intelligent automation with real business workflows while delivering reliable, high-performance user experiences.
Currently, I am actively building and scaling AI-powered SaaS systems, enterprise copilots, fintech platforms, and conversational AI workflows involving RAG pipelines, vector databases, voice interaction systems, and cloud-native infrastructure.
I’m a full-stack software engineer with experience building AI-powered applications, scalable backend systems, automation tools, and modern web platforms.
Over the years, I’ve worked across different areas of technology — from backend architecture and cloud infrastructure to frontend development, APIs, automation, and real-time systems. Recently, I’ve been focused heavily on AI/LLM applications, including conversational systems, speech-to-text pipelines, text-to-speech services, and language learning platforms powered by local and cloud-based models.
I work primarily with:
• Python (FastAPI, Flask)
• Node.js / Express
• React / Next.js
• PostgreSQL
• Docker & microservices
• Firebase
• AWS & Linux environments
I enjoy solving difficult engineering problems, simplifying complex systems, and helping founders or teams move projects forward quickly without unnecessary overengineering.
Some of the things I can help with:
* AI/LLM integrations
* ChatGPT/OpenAI integrations
* Microservices architecture
* REST APIs
* Backend systems
* Authentication systems
* Docker deployment
* Automation scripts
* Web app development
* Debugging difficult production issues
* Performance optimization
* Cloud/server setup
* Speech-to-text and voice applications
I also have a background in Electrical/Electronics Engineering, which shaped the way I approach systems, troubleshooting, and problem-solving in software.
If you need someone who can jump into an existing project, understand systems quickly, and build practical solutions, I’d be happy to help.
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 .NET, Python, Blazor, ASP.NET Core, SQL and agentic AI architecture (LLMs, reasoning engines, Semantic Kernel, LangGraph, tool-calling agents), I design systems where performance, reliability, and intelligent automation aren't optional—they're the baseline.
I deliver AI in production, not prototypes. I’ve architected and deployed AI-powered systems across financial platforms, education and exam automation, and real estate market intelligence, including enterprise-grade solutions for organizations such as The New York Times, Project Management Institute (PMI), Walmart, Merit Wealth, Namfus and BlueberryCMS.

**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, chatbots
- **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.**
