You will get AI Integration: OpenAI, Claude or Gemini Features in Your App
Top Rated
Project details
AI integration for your existing product: OpenAI, Claude, or Gemini features added by a developer who has shipped AI at production level, including intelligent recommendation systems and realtime analysis features where the model is the product, not a gimmick bolted on. The distance between an impressive AI demo and a reliable AI feature is error handling, cost control, and prompt engineering that survives real users. That production gap is what you are buying across. Starter integrates one AI feature into your existing app: summarization, extraction, classification, recommendations, or generation, wired to your data and shipped. Standard adds a production chat interface with streaming responses. Advanced delivers a full AI workflow system with retrieval over your data, prompt management, evaluation, and cost monitoring. Everything runs on your API keys, so usage costs stay transparent and under your control from the first call. Not sure what AI could actually do for your product, or whether it is worth doing at all? Book my $20 consultation and I will tell you honestly, including when the answer is no.

Full-Stack Developer Needed to Finalize Production Website (Vercel + Next.js + Supabase)
⭐️⭐️⭐️⭐️⭐️ Absolutely Outstanding — The Best Team I’ve Worked With!
Working with Mateen, Yawar, and Manzar at Deltacron has been nothing short of an incredible experience. From start to finish, they have exceeded every expectation I had — not just in terms of technical skill, but also in communication, creativity, and overall professionalism.
I came to them with a vision for a modern web platform, and they brought it to life better than I ever imagined. The final product is clean, fast, scalable, and beautifully designed — something I’m proud to show my customers. They didn’t just “do the work”; they truly understood the vision and added their own expertise to make it even better.
The tech stack they used is cutting-edge:
⚡ Supabase for a reliable backend & database
⚡ Next.js for a fast, SEO-friendly, and scalable app
⚡ shadcn/ui & Radix UI for beautiful, accessible, and modern components
⚡ Tailwind CSS for pixel-perfect styling
⚡ Resend for seamless transactional emails
⚡ Hotjar integration for user behavior insights
Every decision was explained clearly, and they made sure the solution was future-proof and easy to scale as my business grows.
What stood out most was their communication and reliability:
✅ Always kept me updated on progress
✅ Took the time to explain technical details in a way I could understand
✅ Suggested smarter solutions when needed
✅ Delivered on time — with zero stress on my side
I’ve worked with other freelancers and agencies before, but this was by far the smoothest and most professional experience I’ve ever had. They cared about the project as if it were their own business and went the extra mile to ensure everything was perfect.
If you’re looking for a team that’s highly skilled, trustworthy, forward-thinking, and easy to work with, I can’t recommend Deltacron enough. They’ve set a new standard for what I expect from a development team.
I’ll 100% be coming back to them for future updates, new features, and scaling my platform — they’ve earned my trust for the long term

Job Success
Peshawar, Pakistan - 2:42 pm local time
Over ten years as a mobile app developer and full stack developer, I have shipped products across three areas where execution quality decides whether a product succeeds:
Mobile commerce and marketplace app development:
As the lead React Native developer on RSVLTS, a US apparel brand, I built a Shopify headless commerce app rated 4.8 stars that drives about 45% of the brand's revenue and holds 98.5% crash-free sessions while 6,000 concurrent users clear 90% of a product drop within the first hour. As a mobile app developer I also built the Narchie marketplace MVP in six months, and the startup raised $692,000 right after my engagement.
AI-powered mobile app development:
I have shipped 10+ LLM-powered features into production as an AI app developer. On HIT AI, a combat sports performance platform, Gemini-powered analysis serves 200 athletes across 427 training sessions, delivering movement insights within 5 to 20 seconds of capture. On our latest platform, Caliper, I built RAG and embeddings into the product core. This is production AI integration, not demos.
Full stack web and SaaS development:
I am also a full stack developer on the web side: Next.js, Node.js, Supabase, PostgreSQL. I architected Kleta, a MERN platform serving 13,000 users where my Stripe integration processes about $3 million a year. I built GFY's MVP on AWS, now past $300K in annual recurring revenue, and my SaaS work on Cubie preceded its $100K early-stage raise. My most recent Upwork full stack delivery, a Vercel, Next.js, and Supabase production platform, earned a 5.0 star review calling it "the smoothest and most professional experience I've ever had."
How I work:
I lead a team of 8 engineers at Deltacron and take on a small number of projects at a time. When I am on your project, I am fully on it: making architecture decisions, flagging problems before they become expensive, and thinking about your product roadmap, not just the current ticket. I am not a code executor. I am a technical partner.
Stack:
React Native · Expo · Next.js · Node.js · React.js · TypeScript · Supabase · PostgreSQL · Firebase · Stripe · OpenAI · Claude API · Gemini
Who this works well for:
Funded startups with a live product that needs to scale or add AI capabilities. Product teams rebuilding or migrating an existing mobile platform. Companies that need a senior mobile app developer with full stack range, not just implementation hours.

Steps for completing your project
After purchasing the project, send requirements so Syed can start the project.
Delivery time starts when Syed receives requirements from you.
Syed works on your project following the steps below.
Revisions may occur after the delivery date.
Kickoff: feature defined and provider locked
We define exactly what the AI feature does, pick the provider and model for your use case and budget, and set up API keys under your accounts.
Integrate: wired into your app and data
The feature is built into your existing codebase with proper error handling, rate limiting, and fallbacks for when the model misbehaves, because it will.
