What I'm looking for

I seek an entry-level ML/AI role focused on speech or NLP research and productization, with mentorship, collaborative teams, and opportunities to publish and scale models.

I am a recent Electronics & Telecommunication engineering graduate with hands-on experience in machine learning and deep learning, particularly in speech enhancement, retrieval-augmented generation (RAG), and knowledge-graph systems.

My undergraduate thesis developed a Phase-Aware Speech Enhancement model using Deep Complex Networks with adversarial training, achieving improved PESQ/STOI over strong baselines; I have authored and co-authored multiple conference papers and submissions in speech and NLP.

I have industry exposure through attachments at Riseup Labs and Cefalo, extensive project work (RAG chatbot, LLM-powered knowledge graph, multi-agent workflows, TTS), and competitive programming experience that demonstrates strong problem-solving and engineering discipline.
