Industry Experience

Software & Internet, Financial Services, Consumer Goods, Telecommunications, Professional Services
    paper Customer Service Dashboard
    Created a comprehensive contact center dashboard featuring:  Multichannel metrics (call/text load balance, ASA, CSAT, FCR)  Hourly/daily trends for inbound calls, missed rates, and agent staffing  Line-specific KPIs (VIP/Support queues) with AHT and response time benchmarks  Data visualization for resource optimization and SLA adherence…
    paper ASD Monitoring Dashboard
    Built a real-time support desk performance dashboard with:  Response time tracking (Agent, Gale, CTI, System) via gauges/tables  SLA compliance monitoring with visual comparisons  Key metrics: Average Handle Time (AHT), abandoned/pending request counts  API-integrated data streams for live updates…
    paper Application Tracking Dashboard
    Designed and developed an interactive dashboard to track grant/application processing . Features include:  Real-time status tracking (In Progress/Not Started/Complete) with overdue alerts  Team/owner performance analytics (completion rates, on-time metrics)  Automated KPI calculations (Average Days to Complete, error detection for date entries)  Visualizations (bar charts, pie charts) for workload distribution and bottlenecks…
    paper Flexible CoT Evaluation Framework
    Created an evaluation system for Chain-of-Thought reasoning across 14 benchmarks. Implemented custom accuracy metrics comparing CoT vs direct answering strategies. Developed threshold optimization and logistic regression models to predict optimal answering strategies while tracking token efficiency.…
    paper Fund Project (Financial Data Processor)
    Built an automated Excel processing system for financial transaction data. Handled both structured and unstructured Excel files with date support, implemented data validation, cleaning, and logging. Features include dynamic column mapping, numeric/text formatting, and dual processing pipelines for checked/unchecked files.…
    paper SPA Prompt Processor

Key features include anchor-based masking, batch processing, and modulated logit fusion with configurable strength parameters.…
    paper Probabilistic Forecast Evaluation Metrics
    This module implements two metrics for evaluating probabilistic forecasts. The probabilistic_alignment() function measures how well predicted probabilities match actual outcome frequencies (lower scores are better). The judgment_separation() function assesses a forecaster's ability to distinguish between different outcome probabilities (higher scores indicate better discrimination). Both metrics use binning techniques to analyze performance across probability ranges. The code is optimized with NumPy for efficiency and supports customizable bin resolutions. These metrics are useful for evaluating confidence calibration in predictive models.…
    paper Sentiment Preprocessing Pipeline
    This Python script provides a comprehensive text preprocessing pipeline for sentiment classification tasks. It includes functions to clean and tokenize text, load and label data from files, pad sequences to equal lengths, create vocabulary mappings, and vectorize text data for machine learning models. The clean_text() function handles contractions and punctuation, while get_data_labels() loads positive/negative examples from specified files. The pipeline supports batching for training and outputs numerical representations of text ready for model input. Key features include proper handling of special characters, efficient vocabulary creation, and one-hot label encoding.…
