I have a great passion for solving problems and can help people with various programming languages, databases, information systems, software related projects.
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 have experience in research, data science, and machine learning. I have worked on projects related to deep learning, renewable energy, and dynamic discount algorithms. My education includes a PhD in Mathematical Modelling and a MicroMasters in Statistics and Data Science.
I’m an **AI engineer and cloud architect** with 14+ years of experience building and scaling real-world software systems. I help startups and product teams turn **LLM ideas into production-ready AI applications**, combining **LangChain/LangGraph**, **Java**, **Python**, **TypeScript**, and cloud-native architecture to deliver reliable, scalable results—not just demos.
I specialize in **developing end-to-end AI systems**, including LLM-powered APIs, RAG pipelines, backend services, and event-driven microservices. With extensive hands-on experience in **Docker, Kubernetes, Azure, CI/CD**, and **Kafka**, I design AI platforms that are secure, observable, cost-efficient, and built to scale from the outset.
Currently working at **Microsoft**, I bring enterprise-grade engineering discipline to fast-moving startup environments. I work comfortably in small, distributed teams, communicate clearly with technical and non-technical stakeholders, and focus on shipping AI features that directly impact users and business outcomes.

Hardik is good practitioner of Test Driven Development approach. Hardik have used Kafka streams for asynchronous event processing in microservice architecture. He is also a winner of more than **5** state level and national level coding competitions.
**He has superb communication and presentation skills.**
Hardik can handle any project needs - from bootstrapping a fresh project to provisioning servers / cloud services to deployments and maintenance.
I build mobile apps from scratch, with supporting backends based on GCP/Firebase. Currently, I focus on Dart and Flutter, but I also have over 14 years of experience in JavaScript, 2+ years of React Native, and experience with Node.JS, MongoDB, and Python.
A little background
I started to code when I was 6, worked with 30+ different programming languages, and built my own called ObjectPath available in Python and Javascript. I hold BSc in computer science. I've been building commercial software since 2004 and was CTO of two startups.
I am a senior Microsoft backend and cloud developer, U.S. citizen, and native English speaker living in the Netherlands and working as a freelancer for enterprise clients across the U.S. and Europe. My working day overlaps with U.S. east coast time from 7am to 2pm, with flexibility to adjust when needed.
I specialize in Azure-based platforms, cloud migrations, backend API development, and DevOps automation, working hands-on daily in C#, .NET, and SQL.
I am an expert with C#/.NET, [ASP.NET](http://asp.net/) (24+ years), SQL Server (28+ years), Azure (15+ years), and Azure DevOps (6+ years), and I frequently step into a tech lead role to help teams improve delivery, architecture, and platform stability, without stepping away from the code.
With 30+ years of experience, including 25+ years in consulting and 20+ years leading development teams, I have delivered enterprise systems for the U.S. Air Force, AT&T, Kaiser Permanente, Dell, Rabobank, 3M, and more, in environments with high expectations around reliability, security, and pace of change.
Recent work highlights include:
* Migrating a complex ASP.NET/SQL Server application to Azure in 5 weeks, with all infrastructure-as-code built from scratch (CCi Global Technologies)
* Cutting production deployment times from 2 days to 20 minutes by redesigning CI/CD pipelines (OpenPath)
* Stabilizing a high-volume SaaS platform with Datadog observability and Polly resilience engineering after months of production failures (ListKit)
Beyond technical work, I bring real leadership and business experience. I co-founded Volare Software 17 years ago and continue to lead it today, generating $8.5M in consulting revenue across 33 clients who have retained me multiple years and across multiple projects to stabilize, extend, and modernize their core platforms.
I am currently seeking a 6-12+ month assignment as a senior developer or tech lead who codes most of the time.
I would be happy to discuss how I could contribute to your team. Please get in touch!
I’ve been passionate about programming since the early 2000s, when I started out with VB6. Over the years, I transitioned into C# and .NET, building a strong foundation in software development and cloud technologies. With more than two decades of experience — and over five years working hands-on with Azure — I’ve developed a deep technical skill set across backend and frontend development, cloud architecture, DevOps, and system design.
What drives me most is the opportunity to share knowledge. I love mentoring others, breaking down complex topics, and seeing that “aha” moment when something clicks. Teaching allows me to give back to the tech community, and I’m excited to support the next generation of developers.
I’ve worked extensively with C#, .NET Core, Angular, Azure, and modern DevOps practices, and I’m confident I can bring both practical insight and real-world experience to learners. I’ve also written about my journey and love engaging with the community on platforms like LinkedIn.
