Cover image for Procedural motion study: a flexible

Procedural motion study: a flexible chain changing shape in a seamless loop. A self-initiated, AI-assisted Python animation with synthetic geometry and fixed segment lengths. This is a design/implementation demo, not molecular dynamics, measured protein data or a scientific result. Client references and scientist review would define any final biological animation. Rendered locally with existing tools; no paid generative-video subscription was used.

Cover image for Marktlabor: a self-initiated market research

Marktlabor: a self-initiated market research dashboard built with AI assistance. Python prepares daily market data and a JavaScript interface provides instrument filters, watchlists, trend indicators, charts and CSV exports. This screenshot shows the working prototype using a dated historical snapshot. It demonstrates data tooling and interface implementation; it does not establish future investment returns or offer trading advice.

Cover image for Real-Time Kafka Streaming Analytics System
Industry:

Real-Time Kafka Streaming Analytics System Industry: Technology, Software, Data Analytics Duration: 5 Months Project Cost: $9,500 Started On: June 2024 Developed a real-time event streaming and analytics platform for processing high-volume transactional data with minimal latency. The client needed a scalable architecture capable of handling live business events, processing streaming data in real time, and generating operational insights instantly. I designed a distributed Kafka-based event pipeline and developed Python consumers for processing and transforming incoming data streams. The system included fault-tolerant stream processing, automated monitoring, Docker-based deployment pipelines, and scalable microservices architecture orchestrated through Kubernetes. Key achievements: • Built a scalable event-driven architecture • Enabled real-time analytics and monitoring • Improved system reliability and fault tolerance • Reduced latency in data processing operations Technologies: Apache Kafka, Python, Docker, Kubernetes, PostgreSQL, GitLab CI/CD

Cover image for CSV-to-PDF reporting extension. This working

CSV-to-PDF reporting extension. This working Python/ReportLab component turns validated records into a readable PDF with separate currency totals, a row-level table and source traceability. Existing output files are protected from overwriting. Part of the same CSV workflow demo shown in this portfolio, built with AI assistance and tested using synthetic records. The image shows the generated PDF, not a client document.

Cover image for Enterprise ETL & Data Warehouse

Enterprise ETL & Data Warehouse Platform Designed and developed a scalable enterprise ETL and data warehousing platform for consolidating large volumes of structured and semi-structured business data into a centralized analytics ecosystem. The client required a high-performance reporting infrastructure capable of integrating data from multiple operational systems while improving reporting speed, data quality, and business visibility. I designed automated ETL workflows using Python and Apache Airflow, implemented optimized relational database models, and developed Power BI dashboards for executive-level KPI monitoring. Major responsibilities included database schema design, SQL performance optimization, API integrations, incremental data loading strategies, data transformation workflows, and automated reporting pipelines. One of the main challenges involved handling inconsistent legacy data structures and improving performance for high-volume analytics queries. I solved this by redesigning indexing strategies, implementing partitioning techniques, and optimizing query execution plans. Results: • Reduced reporting time by more than 70% • Improved data consistency across departments • Automated manual reporting workflows • Increased scalability and maintainability of the data platform

Cover image for CSV validation and reporting: a

CSV validation and reporting: a working Python demo that separates accepted rows, duplicates and exceptions, preserves source files, and creates an auditable HTML report. This self-initiated, AI-assisted sample uses synthetic data, not client records. Demo result: 18 input rows, 12 accepted, 1 duplicate and 5 rows flagged for review. Currency totals are kept separate.
