01 / About

From raw data to systems that decide.

I'm a Data Scientist and ML Engineer with 4+ years of experience building and deploying machine-learning systems across telecom, fintech, computer vision and NLP. My work spans the full lifecycle — from data ingestion and big-data pipelines to model training, fine-tuning, and getting things running reliably in production.

Lately I work hands-on with LLM pipelines, RAG systems, and multi-agent frameworks (CrewAI) at Etisalat by e&, alongside a solid grounding in classical ML, deep learning, and workflow automation. I hold an MSc in Big Data Analytics Management from Bahçeşehir University.

Career trajectory.

Six roles, four countries — internships to consultant, EDA to autonomous agents.

Jul 2024 — Present

Technical Consultant — AI & Data Science Now

Etisalat by e&  ·  Dubai, UAE
  • Built a multi-agent product-scraping system with CrewAI (navigator, extractor, validator agents) to collect catalogues, specs and pricing for the BI team.
  • Developed a multilingual free-text parser using GenAI for entity extraction with Pydantic validation, lifting analytics pipeline data quality.
  • Integrated UiPath RPA with Python to automate multi-step workflows — 95%+ manual-effort reduction on contract EDM renewals.
  • Built a wireless-acquisition propensity model blending ML scoring with business rules; automated CVM campaign list generation via segmentation.
  • Delivered Python/SQL automation for month-end revenue closure across segments — closure effort cut by 99%+.
Dec 2023 — Jul 2024

Big Data Engineer

Evamp & Saanga  ·  Islamabad, PK
  • Developed and ran Spark jobs in Python and Java for large-scale ETL, writing outputs to HDFS and enterprise data warehouses.
  • Built time-series forecasting models (ARIMA, Prophet, LSTM) on multi-year financial data for fiscal-year transaction-volume planning.
  • Optimised pipelines with LLM-assisted tooling to improve throughput and cut maintenance overhead; produced executive Tableau KPI dashboards.
Jul 2023 — Dec 2023

Data Engineer — Computer Vision

DARVIS  ·  Islamabad, PK
  • Built end-to-end pipelines for object detection and image classification — raw ingestion through to model-ready datasets.
  • Trained models for object detection, semantic segmentation and pose estimation; built custom OCR for domain-specific text.
  • Designed image-augmentation pipelines to improve generalisation across varied deployment conditions.
Jun 2022 — Jul 2023

Data Science Engineer — NLP & Speech

Sybrid Pvt. Ltd. (Lakson Group)  ·  Islamabad, PK
  • Delivered brand-health monitoring for enterprise clients using transformer-based ABSA and custom NER models at scale.
  • Built multilingual TTS for English & Urdu (Coqui TTS + voice cloning); ran transcription & diarisation with Whisper ASR and XLSR.
  • Produced Power BI dashboards for stakeholder brand-analytics reporting. Employee of the Year 2022.
Sep 2021 — Apr 2022

Data Scientist Intern — Erasmus Traineeship

VivaDrive.io  ·  Warsaw, PL
  • Ran EDA on customer EV-usage data; built a regression model recommending optimal EV type and fleet size for prospective clients.
  • Pre-processed and visualised large EV-profile datasets; deployed predictive models with Scikit-learn and Flask.
Jun 2021 — Sep 2021

Data Analyst

Plan4Co  ·  California, US
  • Detected anomalies in large datasets with statistical techniques; engineered features to lift model accuracy.
  • Built ETL pipelines on AWS S3 for effective, repeatable data management.

"The best models are the ones that quietly run in production and make the next decision easier."
