AI Engineering & LLM Infrastructure
Experienced in local LLM inference, quantized models, llama.cpp, Qwen, model abstraction, and LLM API integration. Built FastAPI inference services for locally hosted models and offline AI debugging workflows, focusing on performance and reliability.

Backend Engineering & APIs
Strong expertise in Python, FastAPI, Node.js, and Express.js. Experienced in REST APIs, WebSockets, asynchronous services, scalable backend architectures, and AI-enabled SaaS infrastructure. Systems development using Rust, Axum, and Tokio.

Full-Stack Development
Build end-to-end applications using React, Next.js, Redux, and Tailwind CSS. Experienced in responsive UI development, frontend-backend integration, API development, and deploying production-ready applications.

Programming Languages
Proficient in Python, TypeScript, JavaScript, Rust, Java, and SQL across AI engineering, web development, systems programming, and backend infrastructure.

Database & Data Infrastructure
Experience with PostgreSQL, MongoDB, MySQL, Redis, and pgvector. Skilled in relational modeling, schema design, vector search, and RAG architectures for AI applications.

Testing, DevOps & Infrastructure
Hands-on experience with pytest, mock-based testing, Git, GitHub, Docker, Linux, and Vercel. Implemented mock-model fixtures and automated tests enabling CI execution without downloading large model weights.

Distributed Systems & Blockchain
Built a CRDT-based distributed relational database in Rust featuring Multi-Value Registers, Hybrid Logical Clocks, conflict-free operations, and peer replication using Axum and Tokio. Developed Solidity-based smart contract escrow workflows for milestone-driven collaboration.

Agentic AI & Workflow Automation
Develop AI agents for customer support, lead qualification, appointment scheduling, and automated follow-ups. Experienced in integrating LLMs with messaging platforms, calendars, and business systems to automate operations.

Frontend Performance Optimization
Improved page-load performance by 37% through profiling, rendering optimization, and responsive component architecture using React, Next.js, and Tailwind CSS.

Project history

Founder & AI Automation Engineer

Arenova - AI Automation & Marketing
Building an AI automation business focused on practical AI agents and digital systems for service businesses, including conversational front-desk workflows for clinics. Designing agent workflows for customer enquiries, lead capture, appointment coordination, and business follow-ups. Developing the product and delivery stack end to end, spanning onboarding, agent configuration, subscription operations, usage visibility, and customer-facing web experiences.

Project: Compact SLM - Local LLM Serving Platform

GitHub (Personal Project)
Built a FastAPI service for serving a local quantized LLM behind a model-abstraction layer, allowing inference backends to be swapped without changing application call sites. Added pytest coverage with mock-model fixtures so core behavior can be tested in CI without downloading model weights. Technologies: Python, FastAPI, llama-cpp-python, Qwen3, pytest.

Project: Autonomous Debugger - Offline AI Debugging

GitHub (Personal Project)
Built an offline code-analysis workflow that diagnoses execution errors and proposes refactors using local inference, without requiring external model API calls. Technologies: TypeScript, Local LLM Pipeline.

Project: FaceChain Verify - Auditable Visual Verification Pipeline

GitHub (Personal Project)
Built a visual-matching service with SHA-256 and perceptual-hash checks, anchoring deterministic evidence hashes on-chain for tamper-evident verification. Added signature and MIME validation for uploads, a redirect-safe downloader designed to resist SSRF, and a public verification view that recomputes the canonical evidence hash. Technologies: Python, FastAPI, PostgreSQL, OpenCV, Solidity.

Project: Conflict-Free OLTP - Distributed CRDT Database

GitHub (Personal Project)
Built a CRDT-native distributed relational database engine with Multi-Value Registers, Hybrid Logical Clocks, tombstone deletes, and peer replication. Designed a uniqueness-reservation protocol to preserve UNIQUE-constraint correctness during split-brain replication; created a real-time dashboard to inspect synchronization and convergence under injected latency and packet loss. Technologies: Rust, Axum, Tokio, CRDTs, WebSockets, Next.js.

Project: ResearchGit - Research Collaboration Platform

GitHub (Personal Project)
Developed a Git-inspired collaboration platform for research artifacts, applying branching, commits, and merges to research workflows. Connected a FastAPI backend and Next.js frontend with PostgreSQL/pgvector storage and WebSocket-based real-time collaboration. Technologies: Python, FastAPI, Next.js, PostgreSQL, pgvector, WebSockets.

Project: Open Innovation Contribution Escrow (OICE)

GitHub (Personal Project)
Built a collaboration platform using smart-contract escrow to support milestone-based work between contributors and organizations. Implemented the full-stack interface and on-chain escrow flow for milestone submission, verification, and trustless release. Technologies: Solidity, Node.js, React, TypeScript.

Full Stack Developer

AetherLabs
Joined at an early stage and shipped production features across the frontend and backend of AetherLabs Flow, an AI-focused insurtech platform. Built with React, Node.js, and MongoDB; integrated external API schemas and supported AI-powered workflows that surfaced real-time insights. Worked directly with the founding team to move features from requirements through implementation and release.

MERN Stack Developer

Unified Mentor Private Limited
Built and deployed full-stack applications using React, Node.js, Express.js, and MongoDB. Improved page-load performance by 37% through frontend optimization and responsive, component-based interface work. Collaborated across teams to deliver documented, code-reviewed software.

Full Stack Developer - Freelance / Contract

DIGI21 Services
Delivered end-to-end web applications for 7 clients, owning work from UI/UX wireframes to deployment. Built React frontends and Node.js/Express backends with MongoDB or MySQL, while independently managing Git/GitHub workflows.
