AWS-native climate intelligence platform and knapsack budget optimizer mitigating urban heat island risks.
Urban heat island (UHI) effects exacerbate thermal stress across dense communities and legacy infrastructure. Property owners and municipal urban planners lack transparent, cost-quantified engineering tools to model which interventions (cool roofs, high-albedo coatings, window glazing, insulation) deliver the highest thermal resilience under constrained capital expenditure budgets.
Engineered an automated serverless analytics pipeline on AWS. Ingests Open-Meteo climate data, normalizes building physical parameters, calculates multidimensional Heat Vulnerability Scores (HVS), and solves a dynamic 0/1 knapsack optimization matrix to produce actionable retrofitting portfolios with predicted temperature reduction.

Client & Presentation
Responsive scenario builder with real-time budget sliders and live vulnerability dials.
Event-driven commerce orchestration platform bringing ERP-grade order processing directly into Meta WhatsApp.
Small and medium businesses in mobile-first markets process high transaction volumes over WhatsApp but struggle with manual receipt creation, untracked inventory, and race conditions during high-volume promotions due to the absence of automated ERP integrations.
Architected an event-driven AWS serverless backend that decouples incoming Meta webhook web traffic from asynchronous order execution. Utilizes Amazon EventBridge for business event fan-out, DynamoDB transactions for inventory locking, and Amazon Cognito MFA for secure merchant administration.
Architecture
100% Serverless
Zero idle infrastructure cost with automatic scaling on burst traffic
Security Posture
Cognito MFA
Strict multi-factor authentication protecting all merchant admin operations
Event Ingestion

Building under a 48-hour or multi-week hackathon window demands ruthless prioritization. Rather than shipping disposable mocks, every submission adheres to enterprise engineering rigor.
Hackathon prototypes fail most often at edge cases. In HeatCredit, I established 141 passing unit and integration tests covering boundary calculations, schema validations, and mock failure modes.
Monolithic architectures struggle under unpredictable burst traffic. Using AWS SAM, Amazon EventBridge, and DynamoDB single-table designs guarantees sub-second responsiveness without paying for idle compute.
No fake metrics, mock buttons, or simulated endpoints. All submitted architectures are backed by verifiable open source git commits, OpenAPI 3.0 specs, and cloud deployment records.
I actively seek high-impact hackathons, algorithmic sprints, and systems challenges. If you're building a team or organizing an innovation track, let's connect.
