Selected Projects

Each project below is grounded in a real GitHub repository. Click through for code, READMEs, and (for CI/CD Guardian) a live deployment.

01 — Autonomous Agent
Live

CI/CD Guardian Agent

Autonomous AI agent for CI/CD pipelines, deployed live on Render. FastAPI service ingests pipeline signals from a GitHub Actions workflow and issues its own block/allow verdict per build. Groq Llama 3.3 70B provides LLM-driven root-cause analysis on failures. Enforces branch protection, ≥80% test coverage, CVE detection, in-CI secret scanning, and PR approvals via the GitHub API. Multi-channel notifications across Slack, Discord, Teams, Email, and GitHub Issues. 75-test pytest suite enforced in CI, PostgreSQL long-term memory.

03 — SaaS / RAG
Solo

DevScope AI — Codebase Intelligence SaaS

Solo multi-tenant SaaS that lets users chat with any GitHub repository, generate documentation, review pull requests, and score task complexity, all powered by a RAG pipeline over indexed code. Voyage AI voyage-code-3 embeddings (1024-dim) with per-repo faiss-node vector indexes; Groq Llama 3.3 70B streams responses over SSE. Custom evaluation harness with rubric primitives (mustContain, mustCite) for grading retrievals. TypeScript monorepo: Next.js 16 + shadcn/ui frontend, Express 4 API, Prisma + PostgreSQL, Redis + BullMQ async ingestion. Clerk SSO, tiered Stripe billing (FREE: 1 repo / 50 chats/month, PRO: unlimited).

04 — Security / Crypto
Team

Secure E2EE Messaging & File-Sharing

Real-time E2E encrypted messaging and file-sharing platform with a zero-knowledge server (stores only ciphertext and metadata). As part of the cryptography sub-team, implemented the protocol layer client-side via the Web Crypto API: AES-256-GCM for confidentiality, ECDH P-256 key exchange with signed handshake and key-confirmation MAC, ECDSA P-256 signatures, and a per-message HKDF ratchet keyed on sequence number. Replay protection via random nonces and monotonic sequence numbers, server-enforced uniqueness. Safety-number fingerprint verification for MITM detection, plus Node demo scripts showing replay and MITM attacks against secured and unsecured variants.

My scope: cryptography sub-team (protocol design + implementation + attack demos).

Team

MedLaw — Regulatory Compliance Copilot

6-person team build of an AI compliance assistant for medical-device regulatory documents (FDA, ISO 13485, EU MDR) using a microservices architecture. Frontend: Next.js 16 + React 19 + Firebase Auth; backends: Node/Express + MongoDB Atlas and Python/Flask + FAISS + sentence-transformers + Groq Llama 3.3.

My scope: Python document ingestion pipeline (pdfplumber + python-docx + pytesseract OCR + context-preserving chunking). Embeddings, FAISS retrieval, LLM layer, frontend, and auth were built by teammates.

06 — Time-Series ML

Stock Prediction Web App

Academic project: multi-horizon stock prediction (1–14 days) for AAPL, MSFT, and BTC-USD using ARIMA, LSTM, and Ensemble models. Interactive Plotly dashboards, SQLite persistence, and full evaluation with RMSE, MAE, and MAPE. Built to explore classical and deep time-series modeling end-to-end on real market data.

About Me

I'm a Software Engineering student at FAST NUCES Islamabad (graduating June 2026). I care about systems that actually work in production: clean separation of concerns, real evaluation harnesses, deployments people can poke at.

My headline projects: an autonomous LLM agent running live on the public internet (CI/CD Guardian), a solo multi-tenant SaaS with real billing and a custom RAG eval harness (DevScope AI), an exam-prep platform with fine-tuned DistilBERT models (PrepifyAI), and the document ingestion layer of a 6-person healthcare compliance copilot (MedLaw).

I write most of my backends in Python + FastAPI or Node + TypeScript, design databases around PostgreSQL with pgvector, deploy with Docker and GitHub Actions, and ship UIs in Next.js or React Native.

Three months as a MERN intern at RISETECH Pvt. Ltd. taught me what production code review actually feels like — two-week sprints, daily standups, real third-party APIs.

"Available immediately for full-time roles — onsite in Islamabad / Pakistan, or remote worldwide. Especially interested in AI/ML engineering, agentic systems, and full-stack SaaS."

🚀
Ships in production
CI/CD Guardian is live on Render right now. DevScope's billing isn't fake — it processes real Stripe webhooks.

Picks things up fast
Went from MERN intern to fine-tuning transformer models for an FYP in one academic year.

Honest about scope
I tell you what I owned and what teammates owned. Helpful for hiring; less drama in interviews.
