Full-Stack Developer · Cybersecurity Expert · AI Engineer
I build secure, intelligent, and scalable digital products.
Breaking systems to build them stronger. From penetration testing to production-grade platforms.
Fusing machine learning, prompt engineering, and full-stack craft into products that matter.
About Me
I'm Prem Patil — a Full-Stack Developer, Red Team & Cybersecurity Expert, and AI-ML Engineer based in India & Malta. Currently serving as CTO at Study Unifees, where I architect AI-powered EdTech platforms that have impacted 6,000+ students worldwide.
AI is at the core of everything I build. I design and deploy custom AI agents, RAG (Retrieval-Augmented Generation) pipelines, and LLM-powered systems that solve real business problems — from contextual chatbots with conversation memory to intelligent course recommendation engines. I specialize in prompt engineering to optimize GPT-4 and open-source model outputs, and I've integrated AI APIs (OpenRouter, OpenAI) deeply into production systems with robust error handling, token management, and feedback loops.
My expertise sits at the intersection of offensive security and creative engineering. I conduct red team operations using Metasploit, Cobalt Strike, and BloodHound to simulate real-world adversary tactics — then flip the switch and build the very systems those attacks try to break. From cross-platform React Native apps and Laravel backends to cinematic Three.js dashboards and multi-database sync engines, I ship products that are both beautiful and battle-tested.
I'm a strong advocate of Vibe Coding — integrating AI tools into everyday development while maintaining rigorous engineering standards like version control, documentation, and testing. I believe the best software is written when human creativity and machine intelligence work together.

Production-grade products blending complex engineering, cybersecurity awareness, and deep AI integration.
Lead Full-Stack & AI Architect — CTO
AI-Powered EdTech Platform for Study Abroad & IELTS Preparation
A unified, scalable EdTech ecosystem designed to revolutionize how students prepare for the IELTS exam and navigate global university admissions. I unified a robust Laravel-based LMS, a legacy core PHP testing engine, and a cross-platform React Native mobile application — while deeply integrating generative AI to provide personalized tutoring and automated assessments, serving 6,000+ students across the USA, UK, Canada, and Australia.
Architected the AI layer using OpenRouter to dynamically route requests to optimized LLMs (GPT-4 class). Selected models based on latency, token cost, and contextual reasoning for EdTech.
Engineered "Smartu" — a persistent, stateful AI copilot deeply integrated into both the web LMS and React Native app. Authored complex system prompts specialized in IELTS pedagogy and global admissions, enforcing domain boundaries to prevent hallucinations.
Designed a secure backend proxy API (chat_api.php / ai_config.php) to protect API keys, manage token usage limits, and persist conversation histories across cross-platform sessions.
Laid the groundwork for automated IELTS evaluation pipelines — structured data pipelines to pass student writing to the LLM, parse structured JSON feedback, and inject band predictions into the test review dashboard.
Built the official iOS & Android app from scratch with AI chatbot injected directly into native-feeling UI with animations and persistence.
Engineered a custom YouTube-style video player with double-tap seek, playback speed controls, interactive progress bars, and dynamic resizing.
Integrated the SmartIELTS testing engine via optimized WebViews with strict header-hiding and injected JS for seamless native-to-web transitions.
Implemented Apple StoreKit 2 IAP with secure Laravel backend receipt validation. Debugged and patched Swift 5.9 concurrency issues in native iOS pod dependencies for App Store builds.
Engineered automated sync across three MySQL databases (studyunifees, ielts_home, tests) with robust observers to keep user IDs, paid statuses, and AI-generated test attempts perfectly isolated.
Solved critical state-leaking bugs between Laravel LMS and legacy Core PHP. Migrated to centralized Supabase JWT auth with custom middleware as single source of truth across web, mobile, and AI endpoints.
Built Zoho CRM pipeline with background jobs to push registrations, AI interaction events, and college applications directly into the sales team's CRM.
Developed SmartUniMatch — a scholarship discovery engine with backend and UI for global university search, filtering, and application.
Configured EAS CI/CD pipelines with custom pre-build scripts to dynamically patch iOS dependencies. Implemented strict caching policies and Laravel middleware for instant UI updates.

Gamified Web3 Telegram Mini-App — Tap-to-Earn Crypto Platform
A high-performance, gamified cryptocurrency earning platform built natively as a Telegram Mini App (TMA). Designed to onboard users into Web3 smoothly, the app allows users to earn "FAMVpts" through engaging mechanics like tapping, passive auto-mining, social tasks, and interactive 3D mini-games. Successfully merges modern dApp architecture with real-time browser gaming — supporting 50,000+ total users and 12,000+ DAU with high engagement retention through gamified daily streaks, referral programs, and competitive leaderboards.
Hand-built custom 3D interactive experiences ("Fame Run") featuring an optimized cyberpunk-themed environment rendered with Three.js and React Three Fiber.
Implemented custom shaders, post-processing effects (bloom/neon), 3D asset loading, and complex game-state management all running natively inside a React SPA.
Engineered a robust Python/Django backend utilizing Graphene to serve a strict GraphQL API for thousands of concurrent users.
Managed relational data in PostgreSQL tracking delicate state like tap energy, 6-hour mining session calculations, and secure token balances.
Built a fluid interface using Apollo Client for aggressive state caching and optimistic UI updates to mask network latency.
Integrated TON Connect for seamless wallet linking, enabling on-chain token claiming and future NFT distribution.
Built gamified earning mechanics — Tap-to-Earn with custom energy algorithms, passive auto-mining, social tasks, and competitive leaderboards.
Leveraged @twa-dev/sdk to securely authenticate Telegram users, handle native Telegram UI/UX paradigms, and build a frictionless Web3 onboarding flow.
Achieved 95+ Lighthouse scores and <1.5s FCP through lazy loading 3D assets, efficient React state management, and aggressive caching.
