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.

- Own backend architecture end-to-end for a live, production mobile app, from system design through deployment.
- Lead sprint execution and coordinate delivery for the engineering team alongside hands-on individual contributor work.
AI Engineer · Labsbit.ai
Nov 2025 — Feb 2026Estonia · Remote
- Built a production agentic system automating an entire email-based ship buying/selling workflow for a maritime client, replacing a fully manual process.
- Architected LangGraph multi-agent pipelines with Langfuse observability and integrated vector search for retrieval-augmented context.
Software Engineer · Veda AI
Apr 2025 — Aug 2025UK · Remote
- Owned architecture decisions and led client meetings for two Flutter/Firebase consumer apps: a trail-booking app (Encounter Adventures) and a merchant-discounts app (Infinity Club).
- Shipped both apps to the Play Store and App Store.
Software Engineering Intern · Contour Software
Jun 2025 — Jul 2025Lahore · On-site
- Designed and built a food-rescue platform (surplus food pickup/redistribution) as the internship's capstone project.

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.
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.
AutoSense
C++, Qt, Python, Flask
- Sentiment analysis and Trie-based autocomplete tool combining a C++/Qt desktop interface with a Python/Flask backend for real-time text prediction and mood detection; led development as an AI course project.
Priority Scheduler for xv6
C, Operating Systems
- Added a custom priority-based process scheduler to xv6 (MIT's teaching OS), including new syscalls and kernel-level scheduler modifications, backed by an original test suite.
Volunteering

- Organized clothes donation drives for underprivileged communities, covering both collection and distribution.
Volunteer, Ramadan Iftar Drives
Ramadan 2026Chadar
- Helped organize and distribute Iftar meals during Ramadan.
Student Tutor
Aug 2024 — Sep 2024Summer School Bootcamp — NUST partner program
- Tutored 12th-grade students in an intensive pre-university bootcamp covering 21st-century skills and practical tools ahead of their transition to NUST.
Blood Donor
Since Feb 2024NUST Community Services Club (NCSC)
- Regular donor at semesterly campus blood donation drives.
