At Technometrics, I lead the development of high-stakes data systems and security-focused platforms. My work centers on building scalable architectures that handle massive datasets and complex user requirements. Advanced AI & NLP Systems: I spearheaded the development of an NLP classification pipeline for bKash (Bangladesh's largest MFS). By implementing custom LLM prompts and Named Entity Recognition (NER), I achieved an 85.71% accuracy rate in processing thousands of social media interactions for automated sentiment analysis and topic classification. Scalable Web Extraction: I architected and deployed multi-platform scraping engines for Facebook, YouTube, and Instagram. Using Python, Selenium, and Telethon, I built these systems to handle real-time data processing and social media bot automation at scale. Secure API Architecture: I design and maintain high-performance RESTful APIs using FastAPI and Django REST Framework. My focus is on sub-second response times, implementing enterprise-grade security features like JWT authentication, Role-Based Access Control (RBAC), and encrypted credential management. Enterprise Platforms: I contributed to the e-recruitment system for Border Guard Bangladesh, ensuring it could securely handle thousands of applicants through 2FA, SSL-secured payments, and optimized Django/React integration. Data Optimization: I specialize in MongoDB and Elasticsearch, designing optimized schemas and bulk-processing workflows that improved system performance by up to 95% for large-scale social media datasets. DevOps & Deployment: I manage the full lifecycle of applications using Docker and Kubernetes, ensuring consistent performance across environments through automated CI/CD pipelines.
