LinkedIn API Developer Needed for Application Enhancement Stop looking, this is your guy! I started working with Shakib a few months ago and am constantly impressed with his abilities and business acumen. He exceeded all my expectations and helped me launch my product and gain the first few customers.

He is always willing to meet on my schedule and explain things I don’t understand. His communication skills are better thank some people in the US.

I would be happy to serve as a reference any time.

Nilphamari, BangladeshĀ - 6:05 am local time
Need a SaaS MVP shipped, AI built into your product, or a vibe-coded app turned into something production-ready? I've built two production platforms solo — auth, billing, dashboards, AI workflows, the lot — and I do it end-to-end.

I'm a full-stack developer (Next.js + Supabase + Node/Python) who ships real products, not prototypes. I built LittlePostManager, a LinkedIn content tool with AI-assisted generation, scheduling, and analytics, and LifeVitals, a medical appointment booking platform with real-time availability and auth — both from database schema to user-facing UI.

I also bring an edge most developers can't: I'm a practicing veterinarian as well as a developer, so for anyone building in healthcare, clinical, booking, or records-heavy domains, I understand the problem from both sides.

What I can help with
šŸ”¹ SaaS MVPs, end to end — I handle scoping through deployment: auth, billing, dashboards, the API layer underneath, and a frontend that scales. Get to market fast without stitching together five contractors.
šŸ”¹ AI integration that does real work — OpenAI, Anthropic/Claude, and other providers. Custom workflows, multi-step chains, automation, and MCP server integration baked into your product — not an "AI" badge on a thin wrapper.
šŸ”¹ Fixing vibe-coded apps — Built something in Lovable, v0, Bolt, or Replit and hit a wall? I take half-working AI-generated apps and make them functional, secure, and production-ready.
šŸ”¹ Backend & API orchestration — Node/Express or FastAPI, Supabase/PostgreSQL, REST and third-party API integration, real-time features.
Recent work
šŸ”¹ LittlePostManager — LinkedIn content SaaS. AI post generation, scheduling, analytics. Next.js, Supabase, OpenAI.
šŸ”¹ LifeVitals — Medical appointment booking platform. Real-time availability, auth flows, clean patient-facing UI. Next.js + Supabase.
šŸ”¹ Frontend Lead — Led UI architecture for complex, data-heavy interfaces. Designed component systems and shipped production features across a team.

Deployment: Vercel, Supabase, DigitalOcean, and whatever infrastructure fits the project.
Tech Stack: Next.js, React, TypeScript, Node.js, Express.js, FastAPI, Python, Supabase, PostgreSQL, Tailwind CSS, shadcn/ui, OpenAI & Anthropic APIs, MCP servers, REST + third-party API integrations, React Native
