Here are the types of clients I help with my services
If you are looking to build a custom software, or if you already have one but need improvements in performance, SEO, or adding new features, I can help.
Most ideas fail not because the idea is bad, but because the execution is weak. You need someone who can deeply understand your idea and turn that thinking into performant, scalable software without needing constant explanations.
I work with startup founders and early-stage businesses who need:
• MVP development from scratch
• SaaS product architecture
• Performance optimization
• SEO improvements
• AWS cost reduction
• Feature expansion based on real user feedback
Here is a short case study where I delivered an enterprise-level project that generated 2k+ clicks, 200k+ impressions, and $10k+ earnings within just two months of full launch.
The short story is the client already had a project, but it had performance issues, poor SEO, and an expensive AWS setup. After analyzing the project, I offered a solution. The client agreed, and within just one month, I created a better version that stood out in the market. Within just two months of launch, the client gained 300+ users, 200k+ impressions, and $10k+ in earnings. We're still working on adding new features to the website based on user feedback and market needs.
When clients come to me, I deeply analyze their requirements, check competitor sites, and think as a user about what they actually need and expect. Based on that, I provide a solution that is not only technically strong but also strong in terms of user flow.
I can make a new website from scratch or improve your existing one. I focus on making your website do more than just exist. It should help you get results, engage users, save time, and turn visitors into loyal customers.
About me, I am a full-stack JavaScript developer skilled in building user-friendly websites, scalable APIs, and custom web solutions. My focus is on delivering clean, well-optimized code, meeting deadlines, and ensuring clear communication with clients.

I build AI agents, voice pipelines, and n8n/GHL automations that replace manual workflows in production - not prototypes, not demos.
What I have delivered recently:
1. Claude-powered intake agent replacing a manual lead qualification process for a SaaS team
2. Voice AI pipeline built on ElevenLabs and Vapi handling tier-1 support calls end-to-end without human handoff
3. n8n + GHL automation collapsing a 6-step manual agency workflow into a single triggered sequence
4. Multi-step LLM workflow extracting structured data from unstructured documents with 25+ field accuracy
5. Full-stack Laravel + AI SaaS built from spec to deployed in under 8 weeks
I also bring 12 years of full-stack development experience (Laravel, React, Node.js, PHP, Python) - so if your project needs AI features built into an existing app, or a new SaaS product from scratch, I can handle both the AI layer and the underlying system.
Tools & stack: Claude , OpenAI, ElevenLabs, Vapi, Retell, n8n, Makecom, GoHighLevel, Laravel, React, Vue, Node.js, Python, REST APIs, Stripe, Razorpay, AWS, Docker.
I scope accurately, communicate clearly, and build fast. If your project involves replacing a manual process with AI that runs in production, or needs full-stack development with AI integration, I have probably already built something close to what you need.
Thanks,
Digvijay.

Need a top game developer who actually delivers? You're in the right place.
I'm a senior unity developer and unity 3d developer with 9+ years in unity software development and unity video game development. I've built over 150 games and interactive apps. 75+ of those projects were completed right here on Upwork — all with a 100% Job Success score and zero disputes. Mobile games, PC games, VR experiences, AR apps, multiplayer systems — I've shipped them all.
Clients hire me for two reasons: I write clean code and I communicate clearly. No ghosting, no surprises, no messy handoffs. You get daily updates, fast responses, and a game that works exactly how you need it to.
Whether you want to hire a unity game developer or need complete unity game development services — I deliver.
