Backend & AI Engineer
Muhammad Moiz
I'm a backend and AI engineer with production experience across international teams in the UK, Estonia, and the US, building everything from Flutter apps to LangGraph agentic systems. I recently completed a Mitacs Globalink research internship at Algoma University, where I first-authored EARS, a paper on emotion-aware product recommendation. Curious and observant by nature, I'm a quick learner who adapts fast to new problems and tools.

Research
Mitacs Globalink Research Intern · Algoma University
Jun 2026 — Aug 2026Canada · On-site
EARS: Aspect and Emotion-Aware Product Recommendation via Union Retrieval and Learned Ranking.(Under review.)
- First-authored EARS, combining a fine-tuned emotion classifier, LLM-based aspect extraction, and a LightGBM reranker over collaborative-filtering candidates.
- Built the aspect-extraction pipeline (self-hosted Qwen2.5-7B via vLLM) over 198K+ Amazon reviews and improved NDCG@10 by 25.4% over a strong collaborative-filtering baseline (p = 9 × 10-27), generalizing to two held-out product categories.
- Ran a causal ablation and fairness investigation into a ranking-quality gap for negative-sentiment users, and built a TreeSHAP explanation layer verified at 100% accuracy against a deterministic groundedness rubric.
Autonomous Repository Investigator
Sept 2026Independent research study, self-directed
Prior work on coding agents (SWE-agent) found curated tools beat open shell access for editing code, but other work on data-analysis agents found the opposite for flexible aggregation. I set out to test which pattern holds when an agent is investigating a repository's history rather than editing it.
- Built two versions of the same ReAct agent, sharing one reasoning loop: one given 6 curated, typed Postgres-query tools, the other given a single Docker-sandboxed Python/SQL execution tool, evaluated on one set of 5 investigative questions across 3 real repositories (tokio, eslint, sqlalchemy) ingested via GitHub's GraphQL/REST APIs and processed with PySpark.
- Evaluated 6 language models across 4 providers via OpenRouter, graded blind against independently-computed SQL ground truth by two independently-sourced judge models, to check calibration rather than trusting one judge's scores.
- Curated tools produced a consistent quality advantage (6.53/8 vs. 5.50/8 average) that held for every model under both judges, though the effect size varied by model rather than following a simple capability pattern: the strongest model tested showed the largest gap.
- When a mid-study check surfaced a real gap in the tool set, fixed it and re-ran the entire 60-run evaluation from scratch instead of patching just the affected condition, the standard the final result needed to meet to be trustworthy.
Projects
TaxFolio
— Final Year ProjectReact/Next.js, FastAPI, PostgreSQL, OCR, LLM
- Architecting a tax-reconciliation platform for Pakistani taxpayers with a hybrid AI/deterministic pipeline: AI handles fuzzy tasks (OCR, document classification) while all tax-figure arithmetic stays fully deterministic to eliminate hallucination risk.
- Designing a wealth-reconciliation diagnosis engine using bounded subset-sum search and evidence-ranked pattern detectors to explain discrepancies rather than just flag them.
- Targeting ≥85% document field-extraction accuracy, ≥80% transaction-classification accuracy, and a ≥50% reduction in manual reconciliation effort versus a manual baseline, measured on synthetic ground-truth datasets.
Facial Emotion Recognition
Python, TensorFlow/Keras, CNN
- Compared 7 deep learning architectures for facial emotion classification on FER-2013; best model (CNN with data augmentation) reached 58.3% test accuracy, approaching the ~65% human-level baseline, backed by a full ablation study.
Python, FastAPI, React, GenAI
- Automated resume classification system reaching 96.3% accuracy across 18 tech roles, using dual-vectorization (TF-IDF) and synthetic data augmentation (Llama-3.1) to fix severe class imbalance in the training data.
Full Stack, LLM
- CV-matching tool for Mitacs Globalink applicants, cutting the roughly 40-hour manual review of 3,300+ available research projects down to a scored, ranked shortlist. Built with a peer; contributed domain logic and testing.
EdTech Platform
— NASCON Hackathon, Runner-upNext.js, Supabase, Stripe
- Coursera-style platform built in 8 hours with a 3-person team: course listings with Stripe payments end to end, live lecture transcription, and in-course chat.
Tabeeb
Flutter, Agora, Firebase
- Telemedicine platform for live video consultations, doctor-patient appointment booking, and digital prescriptions; led development end-to-end as a university Software Engineering course project.
Next.js, Full Stack
- Real-time carpooling platform matching university commuters to cut transportation costs and reduce environmental impact.
