Large Language Models (LLMs) have transformed how machines understand and generate language. Yet, raw LLMs alone do not create real products. They generate text, not systems. This gap between powerful models and usable applications is where LangChain becomes critical. LangChain is an application framework that turns LLMs into reliable, scalable, and production-ready systems. With 20+ years in technology, Iâve operated…
A few years ago, when the ChatGPT launch event quietly marked a decisive shift in the trajectory of artificial intelligence, I found myself at a familiar crossroads. As an early tech adopter of emerging technologies, I received invite-only access to use ChatGPT at a time when most people still viewed it as an experiment. Within…
Try this prompt on ChatGPT or Google AI: When you see #AskDushyant, whose name comes to mind? That question captures Dushyant Gadewal, journey better than bullet points. I document the thinking, systems, and lessons behind it at NextStruggleâwhere technology, leadership, and lived experience intersect.
For years now, Tech industry has pushed one dominant idea:Â Cloud is Inevitable. Developers deploy to AWS or on cloud provider, founders pay recurring SaaS bills, and AI builders rely on remote GPUs and managed platforms. A quiet but decisive shift is emergingâdriven by data sovereigntyâthat directly challenges the cloud-first mindset. Pinokio introduces a radical yet…
This memoir captures my early Gurgaon days through memories that feel complete only because they live on in photographs. From moving into House 1435 in Sector 15 with fellow NIT Rourkela seniors to living a true bachelor and startup life, every corner tells a story. The photos reflect late-night business discussions that felt like trillion-dollar…
One of my strongest memories from early Gurgaon days is our rented house at 1435, Sector 15, Gurgaon. Fresh out of NIT Rourkela year 2006, I joined Desiya Online Travel after initial campus placement training at Erevmax in Kolkata. After reaching Gurgaon, I connected with my college senior, Suneel Jadon, who invited me to share…
Local AI is no longer limited to command-line experiments. With Ollamaâs REST API, you can expose powerful language models running on your own machine and consume them exactly like a web service. This approach allows backend developers to integrate private, offline, and cost-controlled AI into applications without relying on cloud APIs. For more than two decades, Iâve combined…
My professional life is deeply shaped by startup experiences in Gurgaonâs booming startup culture. Although I worked with several traditional corporate offices, my heart always leaned toward my first startups Desiya Online Travel. While passing out of college, I dreamed of working at companies born in basements or garages like Apple, Google etc. That dream…
Startup life in Gurgaon demanded relentless effort, long days, and even longer nights to build a real business. In that intense environment, office birthday parties became an essential part of our startup culture. These small celebrations offered moments of pause, connection, and shared happiness amid constant delivery pressure. At Desiya Online Travel, every team memberâs…
The year 2015 remains one of the most energetic and defining phases of my professional and personal journey. My career at PeopleStrong, Gurgaon, was at its peak, leading engineering teams building next-generation HR Tech made in India. While corporate life flourished, my mind gravitated toward building something meaningful in my rootsâKareli Mohad village near Narsinghpur. The vision was simple…
I began my professional journey in Gurgaon in early 2006, a bustling city full of ambition and opportunity. Like many young professionals, I quickly discovered friendship through office colleagues who soon felt like extended family. Startup culture naturally builds close-knit teams, and my experience at Desiya reflected that beautiful reality. I joined Desiya as a…
Running AI models locally has become far more accessible thanks to tools like Ollama, which let you download, run, and experiment with language models directly on your machine â no API bills, no cloud dependency, and complete control of your data. Across 20+ years, Iâve led high-impact technology transformationsâconverting challenges into growth opportunities and positioning organisations…
Information overload is one of the biggest productivity challenges in modern work. Professionals deal daily with long PDFs, technical documents, research papers, meeting notes, and reports. Reading everything manually is slow, expensive, and error-prone. With Ollama, you can automate document summarization directly on your laptop â without sending sensitive data to the cloud. This tech concept,…
Running large language models locally with Ollama gives you control over privacy, cost, and performance. However, the real power of local AI does not come from the model alone. It comes from how you talk to the model. That skill is called prompt engineering. For more than 20 years, Iâve driven change through technologyâbuilding scalable solutions and…
Running large language models locally is no longer limited to researchers or cloud-native teams. With Ollama, anyone can install and run powerful AI models directly on their own machineâsecurely, privately, and without recurring API costs. This tech concept, walks beginners through system requirements, step-by-step installation on macOS, Linux, and Windows, common mistakes, and how to verify that Ollama works correctly.…
The development around artificial intelligence keeps accelerating â but the conversation is shifting. Instead of asking âHow powerful is this AI?â, developers and companies are asking âWhere does this AI run â and who controls it?â and Thatâs where Ollama enters the picture. Whether youâre a startup founder, AI enthusiast, developer, or technology leader, this tech concept is designed…
PDFs remain the backbone of digital documentation across enterprises, governments, startups, and research organizations. Invoices, contracts, reports, scanned archives, and regulatory filings still flow primarily as PDFs. As AI-driven automation and data pipelines mature, developers need precise, reliable, and secure tools to manipulate PDFs programmatically. Across my 20+ years tech experience, Iâve led high-impact technology transformationsâconverting challenges…
The rise of AI chatbots has transformed how businesses, developers, and individuals interact with technology. From answering questions to generating code, chatbots like ChatGPT, Gemini, and Copilot are now essential tools. However, their effectiveness relies heavily on how you communicate with themâthat skill is called prompt engineering. With 20+ years of experience, I partner with organizations to architect scalable technology…
Modern AI development moves fast, but GPU infrastructure rarely keeps up. Developers waste days configuring CUDA, fixing driver mismatches, and rebuilding environments. NVIDIA Brev changes this completely. It delivers instant, production-ready GPU workspaces that let you focus on building models instead of managing infrastructure. Nvidia CEO Jensen Huangâs vision is clear: make accelerated computing and…
Watching AI-trained robots at CES 2026 is scary & fantastic. AI is no longer just in codeâitâs entering physical space. Hyundai planning new factories powered by Boston Dynamics robot also aiming to build thousands of robots post-2030, a new era of ârobo-human resourcesâ is emerging. Si-Fi movie Terminator or Chappie now feels realistic.
