I engineer hype real AI systems that ship.
AI & Cybersecurity Engineer at BrainSpark Digital with 2+ years of hands-on experience shipping production AI chatbots, agentic workflows, offensive & defensive security audits, and RAG pipelines.
Building Intelligence, One System at a Time
I'm an AI Engineer at BrainSpark Digital with 2+ years of hands-on experience shipping intelligent applications. My focus centers on Large Language Models, Agentic AI architectures, RAG pipelines, and Computer Vision.
The impact is concrete: 5+ production AI chatbots deployed across business domains, agentic multi-step workflows that cut operational manual toil by 40%, and RAG systems that grounded model reasoning in real-time knowledge bases to eliminate hallucinations.
I hold a B.Sc. in Computer Science & Engineering from Uttara University with certifications from DeepLearning.AI, Hugging Face, and Kaggle. I'm currently open for high-impact AI engineering opportunities and consultations — get in touch ✉.
