Senior Full-Stack Developer | SaaS, CRM, Mobile, MVP & AI Expert
100% Job Success | Top Rated | 15+ Years Experience | Senior Full-Stack Developer I design and build production SaaS platforms, CRMs, mobile apps, and AI-integrated MVPs that hold up under real-world load and scale as your business grows. As a Senior Full-Stack Developer with 15+ years of experience, I help founders, agencies, and product teams turn complex ideas into shipped, production-ready software. My work covers the full stack from React and Next.js front-ends to Node.js and Python back-ends, plus Flutter mobile apps and AI integrations using OpenAI, Anthropic, and open-source models. Whether you need a Full-Stack Developer for a new MVP, a Senior Full-Stack Developer to stabilize an existing platform, or a Full-Stack Developer to lead architecture on a serious build, I can take ownership end-to-end. My current flagship as a Full-Stack Developer is Pixally CRM, a SaaS platform built for wedding photographers and videographers. Pixally is an all-in-one studio management system with bookings, contracts, invoicing, scheduling, automation, AI tools, and analytics - designed to replace the patchwork of separate tools most studios currently use. The architecture spans 30+ modules connected by a D3.js dependency graph, fine-grained role-based access control, an admin panel, and a delivery tracker. One of the largest and most architecturally involved builds I have worked on. Industries I've shipped for as a Full-Stack Developer: ✅ SaaS Platforms & Custom Web Apps ✅ CRM Systems for Photography & Videography ✅ Government & Public Sector Projects ✅ Healthcare, Wellness & Fitness ✅ Fintech & Personal Finance ✅ Real Estate, Travel & Hospitality ✅ E-commerce, Marketplaces & Auction Systems ✅ Legal Tech & Law Enforcement ✅ Drone, Aviation & GIS Platforms ✅ Sports, Matrimonial & Community Apps ✅ Education & Learning Tools ✅ AI Assistants, LLM Platforms & Voice Agents Clients typically hire me as a Full-Stack Developer when they need: - A senior developer who owns architecture, not just feature tickets - A SaaS Developer who can scale a platform past its first 10K users - A CRM builder for vertical-specific industries (photography, real estate, fitness, healthcare, government) - A Mobile Developer for cross-platform Flutter apps shipped on tight timelines - An AI Integration Specialist baking LLM features into real production systems - A Full-Stack Developer for MVPs that actually evolve into long-term products Tech stack: - Front-end: React + Material UI, Next.js, Vue, Flutter, TypeScript, Tailwind - Back-end: Node.js, Python (FastAPI / Django), REST, GraphQL - Databases: PostgreSQL, MongoDB, MySQL, Supabase, Firebase - AI: OpenAI, Anthropic, LangChain, vector DBs (Pinecone, Weaviate) - Infra: AWS, GCP, Vercel, Docker, CI/CD How I work as a Full-Stack Developer: I run discovery before scoping. If your post is a one-paragraph idea, my first reply asks the questions a senior dev should ask before quoting a number. I respond to new messages within one business day, usually faster. If you're planning a serious SaaS, CRM, mobile app, or AI-integrated MVP and want a Full-Stack Developer who takes ownership from architecture to deployment, send me a message with your goals. I'll respond with what I think it'll take to ship it. - Keval
