You will get Claude Opus 4.7 integrated into your app with streaming, tools, and memory

Project details
Claude Opus 4.7 is Anthropic's most capable AI model — and integrating it properly means more than calling the API and rendering a response. I build production-grade Claude integrations: streaming responses that feel instant, tool use so Claude can take real actions in your app, and conversation memory so it actually remembers what users said.
I've integrated Claude into production applications and know where the sharp edges are: token limits, streaming edge cases, tool use error handling, prompt injection risks, and cost management. You get an integration that works reliably at scale, not just in a demo.
What I build:
• Streaming chat UI (responses appear word-by-word, not all at once)
• Tool use / function calling (Claude can query your DB, call your APIs, take actions)
• Conversation memory (short-term context window management + optional long-term storage)
• System prompt architecture (persona, guardrails, context injection)
• Token usage tracking and cost controls
• Error handling and fallback behaviour

Flutter mobile build and ongoing upgrades
Sailesh is one of the best engineers i have ever worked with. He has deep skills across many software engineering practises. We could leave major technical decision making to him, as well as lean on him to lead the build and launch of multiple products.

Flutter Mobile App Debugging for App Store Submission
I've troubleshot my Flutter app for some weeks and there were a few different and unexpected bugs. Sailesh was an amazing support throughout this process because he always knew how to solve these niche issues in a matter of hours. It's been a pleasure working with him and I appreciate the communication and relationship established along the way.

iOS - UI Unresponsiveness Error
Trust is very important when working with someone from Upwork and I am very happy for the relationship I have with Sailesh. For this project, he provided assistance beyond the scope and assisted in providing alternative solutions. Always a pleasure working together

Sailesh was a great! He helped us fix some issues with our Android App. From the moment we started chatting I knew he would be good. He was able to understand instructions clearly and provide critical feedback. He was quick in his work and ongoing communication was excellent. Completed the job 100% successfully. Would highly recommend.

I've been the sole mobile engineer on products that went from nothing to real users — handling everything from first commit to App Store. React Native, Flutter, Expo, Vite, Express, Hono, MongoDB, PostgreSQL. I work across the full stack so you're not waiting on five different people to ship one thing.
I use Claude Code and Codex daily. Scaffolding, boilerplate, debugging loops — the stuff that eats hours. Doesn't replace thinking. But I move faster because of it.
WHAT I'VE BUILT
→ OneTake — mobile lead for a year. Every pivot, every weekend bug, handled. The founder flew out to meet me. His words: "the backbone of OneTake."
→ Kalz — AI nutritionist app, React Native + Expo
→ Solas Compliance — full web and backend for a compliance SaaS
→ Sambad, Flexera — shipped and live
→ ReceiptSasa, Herd — shipped, real users, wound down
AI WORK
→ OCR pipelines and document processing
→ OpenAI and Gemini API integration — production use, not demos
→ Workflows that automated the repetitive stuff clients were doing by hand
→ Claude Code, Codex, Cursor — daily use, not occasional
STACK
→ Mobile: React Native, Expo, Flutter, Dart
→ Web: React, Vite, TypeScript
→ Backend: Express, Hono, Node.js
→ Database: MongoDB, PostgreSQL
→ Cloud: Firebase, AWS, GCP
I reply within 12 hours. Scope is clear? I can usually start the same day.
Drop me a message — glad to take a look at what you're building.
