   Remote

   Founder & Agentic AI Engineer (part-time)

   Independent

   • Prototype and productionize applied AI workflows using Claude, OpenAI, Python, FastAPI, RAG, structured outputs and API-based tools for search, research, operations and knowledge retrieval.
   • Built a voice-enabled RAG search workflow: a voice API, speech-to-text conversion, then a retrieval pipeline that returns results from indexed knowledge sources.
   • Convert successful prototypes into deployable FastAPI services with asynchronous processing, queues, persistence, retries, monitoring and clear API boundaries.

   Software Engineer

   Diametos GmbH

   • Backend engineering for sleep-diagnostics healthtech products at a German medical-technology company, in a regulated, quality-critical product environment.
   • Own features from technical design through implementation, testing and deployment.

3. Jan 2023 to Sep 2025

   Lahore, Pakistan

   Senior Software Engineer

   Nextbridge Ltd.

   • Developed DeepSerp, an AI SEO/GEO optimization platform that helps websites rank on AI search engines such as ChatGPT, Perplexity and Gemini. It crawls complex websites, converts content into structured data, and powers LLM-assisted analysis and recommendations.
   • Built DeepSerp’s universal web scraping layer, which extracts content from any public website stack (React, Vue, WordPress) and feeds the analysis pipeline.
   • Designed and launched a centralized AI search engine in 2024 using Retrieval-Augmented Generation, LangChain and OpenAI embeddings. It syncs products from four backend systems, serves three frontends through one hybrid search (vector plus text) with millisecond-range responses, and solved the client’s main product-discovery problem.
   • Led development of a distributed scraping system that reduced end-to-end processing time from 4.5 hours to under an hour (about 75%) and lowered infrastructure cost by about 40% through adaptive concurrency, queue-based load balancing and resource optimization.
   • Engineered high-throughput ingestion pipelines processing 1.4M+ products daily with 200+ concurrent workers, using enterprise proxy networks (Zyte, Oxylabs) with region-aware routing for geo-accurate requests across the US and Canada.
   • Integrated third-party data sources through Zyte’s scraping API, SERP APIs and product data APIs (BigBox, Best Buy, Sync Centric).
   • Built production crawlers for major retail and automotive platforms, including VIN-based vehicle data extraction: pricing, dealer metadata, listing history and market trends.
   • Normalized scraped catalog, pricing, availability and automotive data into consistent schemas for market analysis, price comparison and feed ingestion, supporting real-time and batch workloads.
   • Optimized persistence and caching with PostgreSQL, Redis and NoSQL databases, applying indexing, query optimization and caching for correct, low-latency access.
   • Owned services end to end: unit and integration testing with a test-driven approach, production deployments, incident investigation and continuous refactoring.
   • Implemented observability for throughput, queue backlogs, error patterns and resource utilization; led code reviews and mentored 4 to 6 engineers.

   • Designed services following Domain-Driven Design principles, with clearly defined bounded contexts and aggregate boundaries, inside a microservices architecture.
   • Improved delivery quality through unit and integration testing (about 75% coverage), code reviews, refactoring and debugging.
   • Worked in Agile/Scrum with Jira for sprint planning, estimation and delivery, contributing to predictable, iterative releases.
