Data infrastructure, decision analytics, and technical PM delivery across pipelines, dashboards, cloud workspaces, and applied ML systems.

I work where technical execution meets delivery: raw messy data, validation checks, status visibility, cross-functional handoffs, and decision tools people can use. Past work includes regulated banking delivery, road-safety ETL on Databricks, Kubernetes research workspaces, explainable risk classification, public-health surveillance, and recent decision-analytics case studies.

Hiring evidence, not slogans.

The proof is strongest when each story shows what was broken, what I built, and what changed after it shipped.

Financial data systemsHDFC Bank
RBI Automated Data Flow processed 500K+ daily records across 8 source systems with no automated validation layer. I built Python and SQL reconciliation plus anomaly detection to catch errors same-day.
$2.1M exposure prevented; manual reconciliation cut 60%.
Data infrastructureAI Institute of South Carolina
Road-safety analytics ETL was running 14 hours per cycle. I rebuilt it as a Bronze/Silver/Gold medallion pipeline on Azure Databricks, processing 2.3M+ records across 5 state-agency sources.
Runtime cut 43%; data prep down 70%; Kubernetes cloud workspace at 99.7% uptime.
Applied ML researchLAWT - Linear Algebra with Transformers
Transformer reasoning models performed well on benchmarks but needed clearer behavior analysis through linear algebra. I implemented the LAWT analysis workflow, replicated the research algorithm across 12+ benchmark datasets, and tracked assumptions, failures, and repeatable model/data issues.
15% accuracy improvement; 3 repeatable model/data issues surfaced.
End-to-end ML productSBDR
Banks classify recovery risk with static repayment rules that miss behavioral signals and cannot explain decisions cleanly. I built a three-branch ML system with FinBERT, BiLSTM, XGBoost, SHAP/LIME, and fairness auditing.
93.4% accuracy; 0.990 AUC-ROC; 30,000 customers.

Focus the proof by role.

Different teams care about different signals. The same body of work maps cleanly into technical PM, data infrastructure, decision analytics, applied ML, fintech risk, and public-sector analytics roles.

Current read

Data and infrastructure work that survives real handoffs.

I am strongest where the job needs both technical execution and delivery discipline: messy inputs, reliable pipelines, validation evidence, stakeholder updates, handoff notes, dashboards, and cross-functional coordination.

  • HDFC: Python and SQL validation across 500K+ daily records.
  • South Carolina: Databricks medallion ETL across 2.3M+ records.
  • HDFC CLMS: BRDs, UAT, defects, release notes, vendor follow-up, and support handoff.
  • South Carolina: Databricks ETL plus Kubernetes workspace availability for remote researchers.

Project stories.

Each card starts with the problem, then the system built, the result, and why that work maps to real hiring needs.

CDC Outbreak AI Dashboard

Python · FastAPI · DuckDB · LangChain · LSTM · React · CDC SODA API

Problem

Public-health analysts had millions of CDC surveillance records but no fast way to query trends, forecast demand, or get answers without waiting for a data pull.

Built

FastAPI backend ingesting live CDC SODA data into DuckDB, LSTM hospitalization-surge forecasting, and a LangChain RAG interface for plain-English questions.

Why it matters

Real-time surveillance plus accessible querying is exactly the category health systems, insurers, and public agencies are trying to operationalize.

Repository

PulsePath Member Activation & Retention

Python · SQL · React · notebooks · pytest · product analytics

Problem

A wearable-membership team needs to know whether guided onboarding should become the default experience without overstating early wins as long-term retention proof.

Built

Fictional, synthetic A/B-style case study with KPI contracts, SQL models, executed notebook, dashboard, requirements, validation report, and testable decision rules.

Result

Guided onboarding showed 89 more activated members per 1,000 signups, while day-60 paid retention stayed uncertain. Recommendation: staged rollout with a preserved comparison group.

Why it matters

Shows business analysis, product analytics, metric definitions, guardrails, privacy-aware scope, and executive communication in one reviewable package.

Repository

Pitcher Fatigue Profile

Python · Streamlit · Statcast · pybaseball · pytest · validation

Problem

Postgame pitcher-fatigue analysis can mistake a noisy velocity slope for a real performance decline if pitch type, game context, coverage, and survivor bias are ignored.

Built

Statcast analysis package and Streamlit dashboard using game-by-pitch-type baselines, complete-game holdouts, bootstrap uncertainty, coverage warnings, and reproducible notebooks.

Result

Ran the complete pipeline on Logan Webb's 2024 season: 33 eligible starts, no supported 1 mph threshold, 0.75 mph held-out MAE, 23 passing tests, and 75% branch-aware coverage.

Boundary

Designed as decision support for historical review, not injury diagnosis or an automatic pitching-change model.

Repository

Datacenter Market Analytics Model

Python · scenario modeling · public sources · executive brief · CSV outputs

Problem

Cloud infrastructure planning needs to compare markets across demand, power feasibility, cooling exposure, fiber, permitting, and risk without pretending public data is internal strategy.

Built

Auditable market-screening model for AI and cloud datacenter capacity planning, with base, power-first, and inference-first scenarios plus explicit assumptions and caveats.

Result

Base case ranks Northern Virginia, Atlanta, and Hillsboro/Portland highest, then shows how rankings shift when power delivery or inference-fit weights change.

Why it matters

Recruiter signal for market intelligence, infrastructure strategy, AI capacity planning, assumption discipline, and concise stakeholder readouts.

Repository

Basketball Decision-Support Model

Python · SQL · Random Forest · bootstrap uncertainty · stakeholder brief

Problem

Basketball decisions need more than a leaderboard: lineup, role, tactical context, sample size, defensive risk, and uncertainty all shape whether a recommendation is usable.

Built

Synthetic possession-level work sample with SQL summaries, random forest possession-value modeling, time-based validation, player role matrix, and lineup decision board.

Result

Generated 4,428 synthetic possessions across 12 lineup profiles, with validation MAE of 0.269 points per possession and recommendations framed through uncertainty bands.

Why it matters

Shows how to turn a vague sports-operations question into a model, validation plan, SQL outputs, and a coaching-friendly decision artifact.

Repository

SBDR: Sentimental-Behavioral Debt Recovery

FinBERT · BiLSTM · XGBoost · SHAP · LIME · Streamlit

Problem

Banks use static repayment rules that miss distress signals in customer communication, miss payment anomalies, and cannot explain decisions cleanly to auditors.

Built

Three-branch ML system: FinBERT for communication distress scoring, BiLSTM for payment sequence anomalies, and XGBoost for five-tier recovery classification.

Result

93.4% accuracy, 0.990 AUC-ROC, 26.1% SHAP signal across 30,000 customers, with explainability and demographic fairness review built in.

Note

Group capstone. My positioning emphasizes the ML pipeline, explainability, risk-classification logic, and analyst-facing delivery.

Repository

AI Portfolio Risk Analytics Platform

Python · Flask · SQLite · scikit-learn · scipy · Monte Carlo · VaR/CVaR

Problem

Individual investors and small teams have limited access to institutional-grade risk analytics like VaR, stress testing, scenario analysis, and sentiment overlays.

Built

Full-stack platform with Monte Carlo simulation, Sharpe/Sortino ratios, historical stress-test scenarios, NLP news sentiment, and reporting through a Flask API.

Why it matters

Direct signal for quant risk, wealth management, banking analytics, and financial modeling roles.

Repository

UMBC SmartShuttle

Apache Spark · Spark SQL · MLlib · Databricks · Python

Problem

Campus transit systems schedule around average demand, then over-provision on normal days and under-provision for events.

Built

Predictive demand model on 700MB+ simulated transit data using PySpark and Databricks MLlib, with route clustering, peak-load analysis, and sustainability metrics.

Result

85% decision-tree accuracy on ridership prediction, with architecture that maps to transit, logistics, and operations scheduling teams.

Repository

Breathe Easy AQI Forecasting

NodeMCU · PMS5003 · MQ-7 · LSTM · XGBoost · Python

Problem

Air-quality monitoring in underserved areas depends on expensive fixed stations, leaving residents without real-time hyper-local insight into what they are breathing.

Built

IoT pipeline from NodeMCU sensors through LSTM/XGBoost forecasting to a monitoring dashboard, with weekly refresh cadence and drift checks.

Result

92%+ forecasting accuracy against official pollution-board readings. Same sensor-to-model-to-dashboard pattern used in industrial IoT, smart city, and environmental monitoring work.

Experience.
