🔥I help startups and growing businesses build fast, scalable web and mobile apps using Python, Laravel, React Native, and React. I work as a full stack developer who can take a product from idea to production with clean code and predictable delivery. If you need a reliable web developer for modern UI work and a strong mobile app developer for iOS/Android builds, I can cover both while staying hands-on as a full stack developer focused on performance, UX, and maintainability. I’ve delivered solutions for founders who need speed now and stability later, and I communicate clearly at every step.🔥
🚀I also lead a web development team, Join.To.IT from Kyiv, Ukraine as co-founder and CEO. We have multiple Laravel developers (Senior PHP and Custom PHP MySQL), Python (Django), and JavaScript (React, Vue, React Native) developers. If your project needs a dedicated mobile app developer, we can staff that role quickly, while I stay involved as a full stack developer to keep architecture, delivery, and communication aligned. When the UI scope grows, a senior web developer can join the project while I remain the full stack developer responsible for end-to-end quality.🚀
I’m an experienced Laravel engineer, React engineer, Vue engineer, and React Native engineer with 14 years of production experience. As a full stack developer I can build backend APIs, admin panels, dashboards, and customer-facing apps, and as a web developer I pay attention to UI details that improve conversion and retention. I’ve completed a wide range of successful projects, from MVPs to large systems with long-term maintenance and continuous improvements.

Stack of technologies we use:
✅ HTML/CSS, Bootstrap, Tailwind
✅ JavaScript (React, Vue, Node.js, Express, AdonisJS, Nuxt)
✅ React Native for cross-platform mobile delivery
✅ API integrations (Stripe, PayPal, Twilio, TextMagic, Xero, DocuSign, Google Maps, Meta APIs, and more)
✅ API development (Laravel, Node/Express, Firebase, Python/Django, Go, REST, GraphQL)
✅ PWA (Progressive Web App)
✅ Databases: MySQL, PostgreSQL, MongoDB, DynamoDB, Elasticsearch
✅ Infrastructure: AWS, DigitalOcean, Firebase, Supabase
✅ DevOps and administration: LAMP, CentOS, Ubuntu
As a full stack developer, I connect the front end, back end, and infrastructure so releases are smooth. When the scope includes native-like UX, I can collaborate with a mobile app developer without slowing down the API roadmap, and a web developer can refine UI flows while we keep the backend stable.
You can hire me as a full stack developer for full ownership, or extend the team and keep me as the full stack developer leading architecture and delivery. If timelines are tight, add a mobile app developer to parallelize mobile features, and add a web developer to accelerate dashboards and front-end work.
Our team has already worked in such industries as:
✅ Marketplace
✅ E-commerce
✅ Travel and Hospitality
✅ Custom ERP (Enterprise Resource Planning)
✅ ChatGPT integration (LLM model in your website front end)
✅ Automotive (car inspection, automotive ERP, car sharing, rental, selling)
✅ Social media (Tinder-like networks, short video platforms, communities)
✅ Sales (CRM systems for sales teams, retail, hospitals, sales departments)
✅ Sport (gym management systems, trainer platforms, fitness apps, club portals)
✅ Legal (document automation, AI-assisted legal processing)
✅ Healthcare (clinic management, booking, mental health software)
✅ Education (LMS, automated training, coaching marketplaces)
✅ Finance (fintech platforms, investment platforms, bank API integrations, calculators)
✅ Manufacturing (shop floor management and automation)
✅ Human resources (HRM systems)
✅ Digital marketing (Meta, Facebook/Instagram, TikTok, Google APIs, analytics)
In our work history you’ll find successful products built with Laravel, PHP, JavaScript, MySQL, React, Vue, WordPress development, Web Development, Full Stack development and React Native, plus multiple systems built with Python (Django, Flask, FastAPI). I also use LLM capabilities and AI APIs (including OpenAI integrations) when they genuinely improve the product experience.
We have 65 senior developers across PHP, JavaScript, MySQL, Python, Go, and Node.js. As a full stack developer, I can jump into an existing codebase, stabilize releases, fix bottlenecks, and plan the next iterations.
Don't hesitate to get in touch with me for further details and fruitful work.

🚀 I build production AI apps — LLM agents, RAG systems, and AI-native products — that actually ship and scale, not demos that break in front of your users.
👋 Hi, I'm Adarsh — an AI-focused Full-Stack Developer and former CTO with 12+ years building software. I've scaled apps to 2M+ users, led engineering as CTO for Canada's largest real estate company, and earned Top Rated with 100% Job Success and $40K+ on Upwork.

📦 Recent AI builds (with my team):
• Stellar Fate — an OpenAI + vector-DB app delivering personalized predictions (10K+ users)
• PlateMate — AI-powered restaurant menu with intelligent recommendations (+65% engagement)

🤖 What I Build
✅ LLM & Agent Applications
Chatbots, autonomous agents, and workflow automation using OpenAI, Claude, and open models. Tool-calling, multi-step reasoning, and guardrails that hold up in production.
✅ RAG & AI Search
Retrieval-augmented systems over your docs and data with vector databases (Pinecone, pgvector), clean chunking, and answers you can trust.
✅ AI-Native Product Development
End-to-end: from model integration to the backend APIs, dashboards, and mobile/web apps your users touch. I ship the whole thing, not just the prompt.
✅ Full-Stack & Mobile Foundation
React, Next.js, Node.js, Laravel on the backend; React Native, Flutter, Swift, Kotlin on mobile. Clean, scalable architecture — no spaghetti, no tech debt.
✅ Fractional CTO / Technical Strategy
For founders who need more than a coder: architecture decisions, code audits, and a roadmap that gets you to investor-ready.
