Project details
I build production-grade SaaS MVPs — not throwaway prototypes that break under real users. Using Next.js, React, PostgreSQL, and FastAPI/Node, I design systems with multi-tenancy, proper auth, and clean architecture from day one, so your MVP can actually scale once you get paying customers.
Recent work includes a multi-tenant booking SaaS with real-time queue management for multiple businesses on shared infrastructure, and a desktop invoicing app I rebuilt from Electron to Rust/Tauri — cutting install size by 96% (300MB to 12MB) while improving speed.
I work end-to-end: architecture, backend, frontend, and deployment — so you're working with one person who understands the whole system, not coordinating between separate frontend/backend freelancers who don't talk to each other. I communicate clearly, flag scope risks early, and deliver code that's documented well enough for your team to maintain after I'm gone.
If you need a working product, not just a Figma file, let's talk.

About Muhammad Roman
Full-Stack Developer & Agentic AI Engineer
Karachi, Pakistan - 4:01 pm local time
Most AI projects die at prototype stage they work in a notebook, break with real users. I've spent two years shipping the other kind. Architecture, backend, frontend, deployment: one person, one point of accountability.
━━━━━━━━━━━━━━━━━━━━
WHAT I'VE SHIPPED
Agentic AI & Automation: AIByTec (Current - Contract)
Multi-agent automation pipelines cutting manual workflows by 80% for enterprise clients. Orchestration with LangGraph, OpenAI Agents SDK, Google ADK, and MCP. Real tool calling, real error handling, real observability.
Full Stack & Real-Time Voice AI Agents Engineer: XponentialAI
Voice agents with streaming LLM backends and custom tool-calling. Sub-second response targets, interruption handling, mid-conversation function execution. The hard part isn't the LLM it's the latency budget and state management.
━━━━━━━━━━━━━━━━━━━━
SELECTED PROJECTS
FBR Invoice Desktop App: Rebuilt Electron → Rust/Tauri. Bundle: 300MB → 12MB (96% smaller). Faster cold start, lower memory, same features. Cross-platform compliance invoicing.
BarberBook: Multi-tenant booking SaaS Product, solo end-to-end. Next.js + Node.js + PostgreSQL. Tenant isolation, scheduling logic, payment flow.
AsianInspection Chat: Secure real-time chat with document handling and AI-assisted responses.
━━━━━━━━━━━━━━━━━━━━
STACK
AI / AGENTIC: OpenAI Agents SDK, Google ADK, MCP, Claude SDK, RAG, multi-agent orchestration, LLM tool-calling, N8N
BACKEND: Node.js, Express.js, Nest.js, FastAPI, PostgreSQL, MongoDB, Prisma, Supabase, Firebase, REST, WebSockets
FRONTEND: Next.js, React, TypeScript, Tailwind
MOBILE / DESKTOP: React Native, Tauri (Rust), Electron
INFRA: Docker, Kubernetes, AWS, CI/CD
━━━━━━━━━━━━━━━━━━━━
HOW I WORK
Scope first. I ask the annoying questions upfront edge cases, load, integrations so we don't find them in week three.
Ship in slices. Working software early and often, not a big reveal at the end.
Build for handoff. Clean code, docs, and a deploy your team can maintain.
━━━━━━━━━━━━━━━━━━━━
GOOD FIT IF YOU NEED
AI agents that do real work with real tools
RAG systems that retrieve accurately, not approximately
A SaaS MVP built properly the first time
A stalled AI prototype rescued and pushed to production
Cross-platform desktop or mobile apps that feel native
I'm direct about timelines and honest when something's a bad idea. If a simpler solution beats an AI one, I'll say so.
Tell me what you're building I'll tell you honestly whether I'm the right fit.
