    About Me I’m a Senior Data/Backend Engineer with a strong software engineering background, specializing in data pipelines, API Development, AI/ML infrastructure and cloud-native solutions. With expertise in AWS, Databricks, Apache Spark, Langchain, HF, MLOps, HFT, and large-scale data architectures, I focus on building scalable, cost-efficient, and production-ready solutions that drive real business impact. My work sits at the intersection of data engineering, machine learning, and cloud automation, allowing me to design, deploy, and optimize AI-powered applications end-to-end. I also received my Masters in Data Science further adding to my expertise with AI/ML. I’ve worked across highly secure environments, including defense-related work, and I bring a security-first approach to data pipelines and machine learning deployments. Whether it’s streamlining ETL processes, optimizing ML models, or deploying AI-driven applications, I focus on solutions that scale efficiently and integrate seamlessly into enterprise cloud environments. What I Offer 🔹 End-to-End AI Development – From data exploration to production deployment, I build and scale AI-driven applications that integrate seamlessly into cloud environments. AI Model Development & Fine-Tuning • Model Development & Optimization: Build and fine-tune models for structured and unstructured data, including computer vision (YOLO), NLP (transformers), clustering, anomaly detection, and time series forecasting. • Transfer Learning & Fine-Tuning: Utilize pre-trained models (BERT, GPT, CLIP, Whisper, YOLOv8, LLaMA, Falcon, etc.) and fine-tune them for domain-specific applications to improve accuracy while reducing training costs. • Hyperparameter Tuning: Automate hyperparameter optimization using Ray Tune, Optuna, and Bayesian Optimization to enhance model performance. • Few-Shot & Zero-Shot Learning: Implement low-data ML techniques to improve model generalization when limited labeled data is available. Retrieval-Augmented Generation (RAG) & Prompt Engineering • RAG Pipelines: Build custom knowledge-augmented LLMs that efficiently retrieve and generate responses using FAISS, Pinecone, ChromaDB, and vector databases. • LLM Fine-Tuning & Customization: Fine-tune LLMs for domain-specific applications, optimizing for efficiency, cost, and accuracy. • Prompt Engineering & Optimization: Craft optimized prompts for LLM applications, including Chain-of-Thought (CoT), ReAct, and Meta-Prompting strategies to enhance model reasoning. • Custom AI Agents & Workflows: Develop LLM-powered AI agents that integrate with databases, APIs, and enterprise systems for intelligent automation. Data Engineering & Cloud Pipelines • ETL & Data Processing: Build efficient, serverless ETL pipelines using Apache Spark, AWS Glue, and dbt to process and transform large datasets. • Streaming & Real-Time Data Pipelines: Architect real-time data ingestion and processing using AWS Kinesis, Kafka, and Flink. • Data Lake & Warehouse Architecture: Design AWS-based data lakes (S3 + Glue) and enterprise data warehouses (Redshift, Snowflake). • Infrastructure-as-Code (IaC): Automate cloud deployments using Terraform, CloudFormation, and Ansible. • Cost-Optimized Cloud Solutions: Implement cost-efficient storage, compute scaling, and serverless architectures for AI/ML workloads. Cloud & DevOps Automation • CI/CD for Data & ML Pipelines: Build automated pipelines for ML training, model deployment, and data processing using AWS CodePipeline, Jenkins, and GitHub Actions. • Kubernetes & Docker Orchestration: Deploy containerized applications with EKS (Elastic Kubernetes Service) for scalable ML models and data processing pipelines. • Security & Compliance: Implement secure access controls, IAM policies, and data encryption to comply with SOC 2, HIPAA, and DoD security standards. • Monitoring & Observability: Set up CloudWatch, Prometheus, and Grafana dashboards to track performance and optimize cloud resources. Why Work With Me? I bring a unique mix of data engineering, artificial intelligence, machine learning, cloud architecture, and security expertise, making me well-suited for highly complex, large-scale projects. Here’s what you can expect: ✔ End-to-end AI & Data Solutions – From raw data ingestion to production ML models, I handle the entire pipeline. ✔ Scalable & Cost-Efficient Infrastructure – I optimize architectures to reduce costs without sacrificing performance. ✔ Security-First Mindset – With experience in highly regulated industries, I ensure robust security & compliance. ✔ Production-Ready AI – I specialize in deploying AI models that deliver real business impact, not just research experiments. ✔ Cloud-Native Expertise – I build solutions that leverage AWS, Kubernetes, and Spark for enterprise-grade scalability. If you’re looking for a data engineer who understands your business objectives, machine learning, DevOps, and cloud automation, let’s connect. 🚀
