About

Professional summary

I am a Machine Learning Engineer and Computer Engineering scholar with hands-on experience building deep learning models, automated data pipelines, and production-oriented AI applications. My work spans machine learning, data science, LLM alignment, software engineering, and AI training workflows.

I specialize in Python-based machine learning development using TensorFlow, scikit-learn, Pandas, and NumPy. I have built classification systems, forecasting engines, ensemble models, feature engineering pipelines, and real-time anomaly detection solutions.

I have experience with AI data training, technical data annotation, prompt engineering, prompt evaluation, and Reinforcement Learning from Human Feedback (RLHF). I focus on evaluating model quality, reducing hallucinations, enforcing domain boundaries, and supporting technically safe LLM outputs.

I have engineered end-to-end data preprocessing workflows for medical image datasets and financial time-series data. My projects include skin cancer classification with EfficientNet, network intrusion detection, quantitative market intelligence, and an LLM-powered solar energy advisory system.

Beyond machine learning, I develop backend and full-stack systems using Flask, REST APIs, React Native, Firebase, and JavaScript. I also have foundational networking and security expertise covering Cisco routing, VLANs, packet inspection, secure code auditing, and penetration testing fundamentals.

I am a continuous learner with certifications in reinforcement learning, data science, networking, and ICT security. I aim to contribute to AI, machine learning, data science, and software engineering teams where I can build reliable, measurable, and impactful intelligent systems.

Career history

Machine Learning & Data Science Intern Industrial Training (SIWES)

Architected and deployed data preprocessing and feature extraction pipelines for more than 10,000 medical imaging files from the HAM10000 dataset and continuous financial time-series data. Built deep learning classification workflows using EfficientNetB0 and custom fallback CNN layers for multi-class skin cancer classification.

Developed an ML-driven Network Intrusion Detection System for real-time packet-stream inspection and anomaly classification. Also engineered a Python and Flask backend for a four-model machine learning ensemble, created real-time market anomaly and predictive signal functionality, and authored more than 15 technical reports, architecture documents, and model performance benchmarks.

Lead AI Developer AI-Powered Solar Energy Advisor Application

Engineered an intelligent domain-specific solar energy advisory application using Python, LLM APIs, prompt engineering frameworks, and REST architecture. The system analyzed regional solar metrics and generated customized engineering specifications.

Designed and executed prompt evaluation workflows and multi-step reasoning benchmarks. Evaluated model responses for hallucinations, domain boundaries, technical accuracy, and safety protocol adherence.

Lead Developer AI Trading Intelligence & Forecasting Engine

Engineered an automated quantitative trading platform using Python, Flask, scikit-learn, Pandas, financial APIs, and a JavaScript charting interface. Orchestrated four machine learning models focused on trend, momentum, volatility, and sentiment analysis.

Implemented high-throughput JSON ingestion from live financial data endpoints, continuous feature extraction, and predictive signal generation for real-time market analysis.

Full-Stack Mobile Engineer Connectly – Real-Time Multi-Modal Social Platform

Architected a React Native mobile application for targeted user matching across professional networking, mentorship, and social interaction streams. Used Expo, Firebase Firestore, and NoSQL architecture to support the application.

Implemented real-time Firestore database synchronization to enable responsive user interactions and up-to-date social platform data.

Network Systems Designer 13-Branch Enterprise Banking Network Infrastructure

Designed a resilient hub-and-spoke enterprise banking network topology spanning 13 branch nodes. Created the infrastructure with Cisco Packet Tracer, OSPF dynamic routing, VLANs, access control lists, and redundant WAN links.

Configured inter-VLAN security policies and validated end-to-end packet delivery across the environment, achieving full packet validation.
