I build minds for machines.

I'm Sajid Islam — a Computer Science undergraduate at FAST NUCES, Pakistan, building generative and agentic AI systems: LLM-orchestrated RAG pipelines, tool-using agents, and the Python backends behind them. My mission: build AI that solves meaningful real-world problems.

Origin

The signal path

Every mind has an origin story. Follow the pulse through mine.

  1. The Student

    BS Computer Science at FAST National University of Computing and Emerging Sciences (NUCES), Pakistan — Aug 2024 to expected May 2028. Coursework in Artificial Intelligence, Data Structures & Algorithms, Database Systems, OOP, and Software Engineering.

  2. The ML Practitioner

    Completed the GIKI × Skylabs Advanced AI Bootcamp — a two-month intensive covering classical ML, deep learning and NLP, agentic AI with LangChain and RAG, and MLOps tooling (Git, DVC, MLflow) end to end.

  3. The AI Engineer

    Shipped a client-facing agentic AI copilot in Comebck Pakistan Cohort 1 (Top 5 of the cohort), and served as a Data / IT Intern at ISPR, Pakistan Army, managing data pipelines and IT operations. I build agentic systems end to end — from Python backends to agents that reason, call tools, and act.

Agentic AI

WhatsApp Commerce Copilot

An agentic AI copilot that answers clothing-brand customers in Urdu and Roman Urdu across WhatsApp and Instagram DMs — with catalog-grounded replies on sizing, delivery, and Cash-on-Delivery confirmation.

Agentic AILLM IntegrationReactFastAPILangChainDocker

Problem: Pakistani clothing brands lose sales to unanswered Instagram and WhatsApp DMs, and to a 30–35% Cash-on-Delivery return rate driven by unconfirmed orders. Before building, our squad validated this on the ground — messaging 16 Pakistani clothing brands as real customers within one hour to quantify the unanswered-DM problem, then interviewing brand owners to shape the product.

Solution: An agentic AI copilot that reads customer questions in Urdu and Roman Urdu across WhatsApp and Instagram DMs and replies instantly with catalog-grounded answers on sizing, delivery, and COD confirmation — with a one-tap handoff to a human and live stock management from a React dashboard.

Context: Built in a 4-person squad during Comebck Pakistan Cohort 1 — an 8-week, YC-style accelerator and the first Pakistani product accelerator. Selected as a Top 5 project of the cohort.

Technology: Agentic AI and LLM integration, React dashboard, Python/FastAPI backend, LangChain, Redis, and Docker for a fully containerised stack.

Data Engineering

Entropy-Aware Data Preservation System

A production-style PostgreSQL ETL pipeline that computes Shannon entropy through automated triggers and routes records through rule-based preservation logic.

PostgreSQLPythonPHPETLBootstrapShell

Problem: Long-lived systems accumulate state snapshots faster than they can be stored, but discarding data uniformly loses the records that actually carry information.

Solution: An ETL pipeline that computes Shannon entropy for each record via automated database triggers, then routes it through rule-based preservation logic — discard, compress, preserve, or archive — across a normalized (3NF) 10+ table schema. A real-time PHP dashboard surfaces entropy trends and audit logs.

Technology: PostgreSQL with PL/pgSQL functions, triggers and views; Python; PHP dashboard with Bootstrap; Shell tooling; Docker Compose for a one-command environment.

GIKI × Skylabs Advanced AI Bootcamp

A two-month intensive taking me from the mathematics of modern AI through to deploying autonomous agents — completed end to end.

PythonDeep LearningNLPLangChainRAGMLOps

What it covered: A two-month intensive spanning classical machine learning, deep learning and NLP, agentic AI with LangChain and RAG, and MLOps tooling (Git, DVC, MLflow) end to end.

Curriculum arc: mathematical foundations for modern AI (linear algebra, calculus, probability, information theory) → NLP and transformer architectures including self-attention, BERT and GPT with hands-on fine-tuning → post-training and alignment (instruction tuning, RLHF/RLAIF, PEFT, and Chain/Tree/Graph-of-Thought reasoning) → agentic AI with ReAct, tool-using agents, memory and multi-agent orchestration, plus advanced RAG → inference and deployment (ML/LLMOps: versioning, CI/CD, serving, observability, cost and security) → a capstone building and deploying an autonomous agent system.
