You have a product idea, a real-time system that needs to scale, an AI application that needs to actually retrieve the contextual data, or a backend that is falling apart under load. Now you need someone who understands distributed systems, not just CRUD. That is where I come in. I am a Real-Time Systems Engineer and Full-Stack Developer with 4+ years of experience building event-driven backends, RAG-based AI pipelines, and code-first automation for founders and engineering teams who need systems that perform under pressure. I work across the full stack with a backend-heavy focus: MQTT | Kafka | Socket io | Node js | Fastify | Next js | React | PostgreSQL | MongoDB | Docker | AWS | Redis | LangChain | pgvector | React Native I do not just write features. I think about data flow, system boundaries, failure modes, and what happens when your user base grows 10x overnight. I ask the questions most developers skip. I plan the architecture before touching the code. And I stay close to the system until it is ready for production. I will tell you when an event-driven approach is the right call. I will also tell you when it is overkill and something simpler will do the job better. Selected Product Experience - Senior Software Engineer at DevNauts Where I lead technical execution, standardize engineering workflows, and have delivered 8 full-stack projects in the first 10 months across real-time systems, SaaS platforms, and automation tools. -Built QuantLayer A production-grade real-time device monitoring platform processing live data streams across a Zero Trust security model, with a full MQTT to Kafka ingestion pipeline, distributed microservices architecture deployed on GCP, and a Socket io powered frontend that reflects device state instantly with zero polling and zero data loss. - Built Visent A facial recognition visitor management system with AWS Rekognition, RFID and QR-based access control, multi-tenant architecture, and real-time visitor logs. - Built DriveDirect A React Native driver tracking app with live location updates, offline database sync for low-connectivity areas, and a vehicle appraisal workflow to prevent false damage claims. Graduated from NUST, one of Pakistan's top engineering universities, with a BS in Software Engineering. What I Can Help With Real-time systems MQTT | Kafka | Socket io | WebSockets | SSE | Redis Pub/Sub | BullMQ | Event-driven microservices | Live dashboards | Device monitoring | Collaborative tools RAG and AI pipelines LangChain | OpenAI API | Anthropic API | pgvector | Pinecone | Document ingestion | Chunking strategies | Semantic search | LLM orchestration | AI chatbots | Knowledge bases Code-based automation Custom workflow engines | Webhook pipelines | Async job queues | Cron schedulers | Third-party API orchestration | Retry logic | Failure handling | Stripe | Nodemailer Backend and APIs Node.js | Fastify | Express | REST| JWT | OAuth | PostgreSQL | MongoDB | Supabase | Xano | Microservices | Docker | Docker Compose Frontend and mobile React | Next js | TypeScript | Redux Saga | MUI | Tailwind | React Native | Offline sync | Admin dashboards | Real-time UIs Devops AWS | GCP | Docker | Nginx | CI/CD | GitHub | BitBucket A Good Fit If You are building something where data needs to move fast, AI needs to retrieve accurately, or workflows need to run without a human in the loop. You want a developer who understands systems, not just syntax. You care about architecture, reliability, and code that holds up as your product grows. Not a Good Fit If You want the cheapest option, need someone to build fast and skip the thinking, or are looking for a developer who will not push back when something is being built the wrong way. So if you are building something that needs to work at scale, let's talk.
