AI chatbot for scientific text analysis

Data Scientist Chatbot LLM Python ...
Data Scientist
  • Built an AI chatbot for an agricultural-sector client?s R&D department, creating retrieval and text-analysis workflows across 1,000 scientific publications with Streamlit interfaces, LangGraph-based reasoning flows, and source-aware prompting.
  • Built a Streamlit-based chatbot front-end with added monitoring features, including RAG endpoint health checks.
  • Implemented the chatbot logic and state flow using LangGraph.
  • Developed an AWS vector database deduplication process to regularly clean and reprocess the document corpus.
  • Built an in-session text analysis feature, allowing researchers to upload short texts and use them directly in the chatbot context without administrator support.

Enterprise automotive cybersecurity platform

Data Scientist Data Engineer Python Kubernetes ...
Data Scientist
  • Delivered enterprise data and backend components for an automotive cybersecurity platform covering vulnerability, risk, and incident workflows across a fleet of 20M+ vehicles, integrating 30 internal and external APIs.
  • Redesigned data architecture and implemented a custom data-fusion approach for the automotive platform, reducing processing time from 4 hours to 20 minutes, while improving data normalization, reliability, and downstream availability through Superset BI and outbound APIs.
  •  Lead end-to-end developing of Python- and SQL-driven backend services running on Kubernetes

    meetings with business representatives, frontend and L2 support teams.

  • Managed downstream systems such as Superset BI and outbound APIs

  • Facilitated technical decisions within cross-functional

Data Scientist Terraform Technical Documentation SVM ...
Data Scientist
  • Developed a predictive maintenance ML prototype for a heavy-duty vehicle client using ECU time-series data from approximately 500 vehicles, deploying a model endpoint to support repair-alert workflows up to one week before required maintenance intervention.
  • Designed AWS cloud and MLOps infrastructure with Terraform and MLflow, enabling 20 data scientists to deploy, monitor, and iterate on model artifacts for NLP and computer vision proof-of-concepts.
  • Supported consulting delivery beyond implementation by preparing SOWs, technical proposals, and go-to-market material for pharma, chemical, and manufacturing initiatives, while mentoring junior engineers and supporting a three-month vendor transition.

Social-network research and data analysis

Research Specialist and Lab Manager
Research Specialist and Lab Manager
  • Analyzed social-network navigation behaviour from 150+ participants using mixed-effects regression and reinforcement-learning successor representation models in R and Python.
  • Built web-based tools for large-scale behavioural data collection, contributing approximately 4,000 lines of JavaScript and enabling online data acquisition from 1,000 participants.
  • Gamified an experimental behavioural task to support participant learning, reducing the required training routine from two days to 90 minutes.
  • Coordinated research workflows with 2 postdoctoral researchers and a 10-person scientific team, covering protocol documentation, ethics committee preparation, data privacy procedures, and grant administration.

Computational neuroscience research

Research Fellow and Computer Lab Manager
Research Fellow and Computer Lab Manager
  • Modeled patch-leaving foraging behaviour as a reinforcement-learning optimization problem, using the Marginal Value Theorem as a benchmark for evaluating agent performance.
  • Designed research projects on the interaction between model-free reinforcement learning and model-based cognitive processes, including working memory, to study learning efficiency across tasks of varying complexity.
  • Applied multivariate analysis and feature-selection methods to 40+ MEG and fMRI brain recordings, with additional hands-on neural network modeling experience in PyTorch.
  • Presented research at 40+ local and international events and contributed to interdisciplinary scientific communication across pharmacology, psychology, and computational neuroscience, including an opinion piece selected as an Editor?s Pick in 2022.
