Startups, enterprises and public-sector organizations bring me in when the product needs strong technical decisions, not just execution - production AI systems, SaaS platforms and fintech, from architecture to live deployment. Most engagements start with a fixed-price design phase that defines architecture, scope and roadmap, then convert into fixed milestones, so delivery stays structured and budget predictable. Rate $125-150/hr depending on complexity; most work is delivered as fixed-price milestones. What I specialise in: AI/LLM systems - RAG pipelines, multi-tenant AI assistants, agent orchestration, Claude/OpenAI integrations, structured outputs, eval pipelines. SaaS platforms - multi-tenant architecture, subscription billing, RBAC, admin backends, scalable APIs across web and mobile. Fintech/compliance - ACH, Stripe Connect, idempotent payment webhooks, audit logging, GDPR-compliant data. Govtech/regulated - transparency platforms, donor-funded compliance, multi-language reporting. Blockchain/Web3 - Solana smart contracts, SPL tokens, DeFi integrations. Selected results (live demos and links in the Portfolio section): Minerva (active production) - multi-tenant AI assistant platform architected end to end: organizations upload document libraries and deploy embeddable chatbots on their own knowledge base. Hybrid retrieval (BM25 + dense vector + semantic), Entra ID + RBAC + MFA, full tenant isolation, golden-query eval harness in CI. NestJS, Next.js, Azure OpenAI. Diginak.ai (active production, lead architect) - logistics document automation that auto-processes ~78% of inbound PDF/CSV/Excel with zero human touch; the remainder routes to human review with confidence scores. Claude API + tool use, state-machine workflow engine, retry/idempotency, 850+ automated tests. NestJS, PostgreSQL. Walletta AI Cashier (concluded May 2026, 5-star) - real-time voice agent with sub-500ms perceived latency. Claude + GPT-4o orchestration, structured tool calls with confidence-scored routing, persistent WebSocket, retry with circuit breaker. LiveKit, Deepgram, ElevenLabs, NestJS. Damen Capital Portal (concluded May 2026, 5-star) - loan-servicing portal for a private lender with the full ACH lifecycle: tokenization, NACHA returns R01-R85, HMAC-verified idempotent webhooks, append-only audit log, OAuth 2.0 + RBAC, scheduled reconciliation. NestJS + Fastify, Supabase. PulseYourBiz (active production) - all-in-one SaaS for service providers: bookings, payments, invoicing, CRM, analytics.

Hi! I'm Muhammad, a full-stack developer with 6+ years building SaaS products with real product logic: billing, roles, dashboards, CRMs, messaging, APIs, reports, and AI-powered workflows. I build and repair React, Next.js, Node.js, Express, NestJS, MongoDB, PostgreSQL, Supabase, and TypeScript apps that need to hold up in production. Most developers can build screens. The harder part is building the system behind those screens: the data model, user permissions, payment flow, admin logic, API structure, third-party integrations, AI features, deployment setup, and the edge cases that show up after real users start using the product. Results That Speak: - 6+ years of experience - Top Rated Plus (React | Next.js | Node | AI Integration) - 5 Star client reviews for speed, reliability & communication - 6,000+ hours logged | $300k+ earned | 100+ projects delivered That's where I usually fit in. I work best on SaaS platforms, AI-powered tools, internal dashboards, CRMs, marketplaces, booking systems, real-time apps, and web/mobile products where the application is more than a basic frontend. The kind of problems I handle: - Turning a rough SaaS idea into a working MVP with frontend, backend, database, auth, payments, and deployment - Cleaning up React or Next.js apps that became hard to maintain - Fixing slow dashboards, broken APIs, unstable database queries, Stripe issues, auth bugs, and deployment failures - Building admin panels, user roles, subscription flows, notifications, messaging, reporting, and workflow automation - Integrating Stripe, Stripe Connect, Twilio, Google Maps, Firebase, OAuth, JWT, webhooks, and custom APIs - Adding real AI features (OpenAI, Claude, Gemini, RAG pipelines, MCP, agents) where they make the product more useful, not just because "AI" sounds good Recent product work includes: - Averi AI - AI marketing SaaS built with Next.js, PostgreSQL, and AI integration. Led engineering and helped raise $5M seed funding. - Autobunny - platform for car dealerships that reduced manual dealer tasks by 60%. - Westepforward - AI-based EdTech exam prep platform with real-time analytics and admin tools. - Chlk - Fabric.js / Konva.js canvas app built for NFL coaches with rich play-design features that cut design time by 50%. - Traceo - browser-based bug capture tool for dev and QA teams (Co-Founder & CEO). Built on Next.js, NestJS, and Supabase with a Chrome extension and AI-assisted reporting. Tech I use Daily: - Frontend: React.js, Next.js, Tailwind, Fabric.js, HTML/CSS - Backend: Node.js, NestJS, Express, GraphQL, REST - Databases: MongoDB, PostgreSQL, Supabase, DynamoDB - Mobile/Desktop: React Native, Electron.js - Cloud & DevOps: Vercel, AWS, Heroku, Hostinger - AI Tools: OpenAI (GPT-4), VAPI, Claude, Together.ai, LangChain, n8n When I start on a project, I don't jump straight into code. I first look at the product goal, user roles, database structure, API flow, payment logic, integrations, and deployment plan. Bad architecture early usually turns into expensive cleanup later, so I prefer building it correctly from the start. I'm a strong fit if you need a developer who can take ownership of a real product, make technical decisions, and ship AI SaaS features that work beyond the demo stage. Send me your app details, current stack, and what needs to be built or fixed. I'll respond with a practical technical plan.

Most engineers can write code. Fewer can take a vague product idea, architect it properly, and ship something that holds up in production six months later without it becoming someone else's problem to maintain. That's the work I do. I'm Vikram, a Senior AI and Full Stack Engineer with 6+ years of experience, $70K+ earned, and 25+ projects delivered on Upwork. I work with startups and product teams who are building things that actually need to work: AI-powered systems, scalable SaaS backends, and full stack platforms that grow with the business. If you have ever been handed code that "technically works" but nobody can explain, or an AI demo that never made it to production, you'll know exactly why architecture and delivery discipline matter. That's where I come in. AI Systems and Agent Development: - LLM integrations using OpenAI GPT-4o, Anthropic Claude, Gemini, Mistral, and Vertex AI - AI Agents and multi-agent systems using LangGraph, CrewAI, AutoGen, LlamaIndex, and Mastra - RAG pipelines with Pinecone, Weaviate, ChromaDB, and FAISS - Voice AI agents using ElevenLabs, Whisper, VAPI, and Deepgram - MCP (Model Context Protocol) integrations for tool-connected, context-aware agents - Long-term agent memory with Mem0 and Zep - AI workflow automation using n8n, Make, and Zapier - Document intelligence, semantic search, and knowledge base systems - AI-powered automation for legal, HR, sales, and enterprise workflows Backend Architecture and APIs: - Node.js and Python backends using FastAPI, Django, and Express.js - REST and GraphQL APIs built for scale and long-term maintainability - Multi-tenant SaaS architecture with authentication, RBAC, and audit logs - Payment integrations and subscription billing systems - High-performance database design using PostgreSQL, MongoDB, and MySQL Full Stack Development: - React and Next.js (TypeScript) for SaaS dashboards, admin panels, and client portals - Real-time features and API-driven frontends - Vercel AI SDK for AI-native web applications Cloud and DevOps: - AWS, GCP, and Azure deployments - Docker, CI/CD pipelines, and GitHub Actions - Scalable infrastructure with monitoring and error handling built in from day one, not bolted on after launch Industries: - AI/SaaS and Product Startups - FinTech and Payments - LegalTech and Contract Automation - HR Tech and Workforce Platforms - EdTech and Learning Platforms - Healthcare and Digital Health - Logistics and Supply Chain - Enterprise Automation and Internal Tools - E-commerce and Marketplace Platforms - Real Estate and PropTech - Marketing Tech and Growth Platforms - Cybersecurity and Compliance Tools - BI, Analytics and Data Platforms What Clients Say: "Vikramjeet was dedicated to providing timely and complete solutions. His communication was regular, he was able to meet deadlines, and he has a broad range of technical skills." "With minimum communication, he understood what we need and implemented it right away. What impressed me most was his commitment to delivering fast and his commitment to the deadline."
