## Experience

- Agentic AI & Front-end Engineer — LogicEra (Cloud & AI Partner), Dubai, UAE (remote), Oct 2025 – Present. Design and build agentic AI workflows for client solutions: LLM agents that plan, call tools and APIs, and carry out multi-step tasks. Build the front ends of AI products, including chat and assistant interfaces with streaming responses, tool-call progress and human-in-the-loop review. Integrate LLM providers and retrieval-augmented generation (RAG) over client data, with prompt design, context management and guardrails. Develop Python and FastAPI services that orchestrate agents and expose them securely to web and mobile clients. Test and harden agent behaviour before release, handling failures, cost and latency in production.
- Senior Software Engineer (Cross-Platform) — Al Taif Group, Islamabad, Pakistan, Mar 2022 – Oct 2025. Led an engineering team architecting and scaling enterprise delivery and e-commerce applications serving thousands of active users. Designed modular application architectures from scratch, standardising state management, directory structures and design patterns across company repositories. Implemented automated CI/CD pipelines and multi-flavor environments (Dev, QA, Production), reducing deployment errors and accelerating release frequency. Owned complete release lifecycles across App Store Connect and Google Play Console: publishing pipelines, certificates and compliance. Ran systematic code reviews and performance audits, optimising memory footprint and rendering performance for low-spec devices.
- Software Engineer (Flutter) — Turing, Remote, Aug 2023 – Dec 2023. Engineered full-stack marketplace features with Python, Django REST Framework, Docker and PostgreSQL. Configured multi-environment build flavors and CI/CD automation for cross-team development and staging. Implemented reactive state management with Riverpod for responsive UIs with complex data-syncing needs. Optimised performance: thread efficiency, battery consumption and network requests.
- Software Engineer (Flutter) — AppWowZap, Pakistan, Apr 2021 – May 2022. Developed cross-platform client apps in Flutter and React Native for iOS and Android. Integrated POS thermal printing through native method channels. Built real-time messaging, payments and location features with WebSockets, Stripe and the Google Maps API. Implemented Firebase Cloud Messaging push notifications and REST API integrations.
- Software Engineer (Flutter) — EmCentrix, Pakistan, Nov 2019 – Apr 2021. Practised test-driven development and built automated test suites ahead of production releases. Established early CI/CD pipelines for build, test and distribution. Led greenfield Flutter development while refactoring legacy native Android code into modern architectures.
