"Good software is not about clever code — it's about systems that remain comprehensible, maintainable, and honest about their own complexity."
I work at the intersection of backend engineering and applied ML infrastructure. At Dubizzle Labs, I built and optimized REST APIs serving tens of millions of users across Dubizzle, OLX Pakistan, and Zameen.com, and led a search migration from Algolia to Elasticsearch that reduced infrastructure costs by 70% while handling over 32 million daily requests. My work spans API design, e-commerce systems, and agentic developer tooling built with LangChain and LangGraph.
I think carefully about how systems scale and where complexity should live. At Visnext, I led development of a full payment management platform integrating Samsung Pay, Apple Pay, Google Pay, and Checkout.com, and built real-time Kanban tooling for MSPs that cut task management time by 50%. Now at 10Pearls, I focus on MLOps infrastructure — MLflow, KServe, Kubeflow, and Terraform — building the pipelines that bring models reliably into production.
Building robust REST APIs with Django and FastAPI, designed for scale. Proven across high-traffic platforms including Dubizzle, OLX Pakistan, and Zameen.com serving tens of millions of users.
Architecting search systems with Elasticsearch and Redis. Led Zameen.com's migration from Algolia to Elasticsearch, reducing infrastructure costs by 70% at 32M+ daily requests.
Deploying and managing ML infrastructure using MLflow, KServe, and Kubeflow on Kubernetes. Building reliable training and serving pipelines with Terraform and AWS for production environments.
Designing LLM-powered workflows with LangChain and LangGraph, including JIRA-to-PR automation, code review agents, and SEO tooling driven by Google Search Console data.
Building payment platforms integrating Samsung Pay, Apple Pay, Google Pay, Tamara, and Checkout.com. Delivered OPMS with a custom Vanilla JS SDK, real-time dashboards, and SSO via Keycloak.
Shipping end-to-end features across React, TypeScript, and Python backends. Delivered seller tools, subscription flows, and cross-platform listing sync for e-commerce and classified platforms.
A decade of partnering with high-growth companies to solve their most critical challenges.
Building MLOps infrastructure: deployed MLflow for experiment tracking and model registry. Deploying models with KServe on Kubernetes; building ML training/serving pipelines with Kubeflow. Ramping on Terraform for infrastructure-as-code and LangChain / LangGraph with vector databases for agent workflows. Stack: MLflow, KServe, Kubeflow, Terraform, AWS.
Built and optimized REST APIs for Dubizzle, OLX Pakistan, and Zameen.com, serving tens of millions of users across three platforms. Led Zameen.com search migration from Algolia to Elasticsearch, cutting infrastructure cost 70% while handling 32M+ daily ES requests. Shipped e-commerce features for OLX Seller Center and Dubizzle ProTool, including subscription flows and cross-platform listing sync.
Continued OPMS development: added payment gateways and improved transaction tracking, analytics, and security. Built a Kanban Board Tool for MSPs (DRF + React) with real-time sync from Connectwise and Autotask; drag-and-drop cut task-update time 50%. Led a small dev team across concurrent projects, keeping delivery on time throughout.
Started on the OPMS payment management platform, integrating Samsung Pay, Apple Pay, and Google Pay alongside Checkout.com. Built foundational REST endpoints and a Vanilla JS SDK later adopted across the product.
