Senior AI/ML Engineer | Full Stack Developer | AI Agent, RAG, OpenClaw
I am a Senior ML Engineer with over 8 years of experience delivering end-to-end AI solutions that drive real business impact. My journey spans from building foundational data systems to architecting sophisticated generative AI applications, and I bring a unique blend of mathematical rigor and practical engineering expertise to every project. Throughout my career, I have developed and deployed production-grade machine learning models, designed intelligent AI agents, and built full stack applications that seamlessly integrate cutting-edge AI capabilities. My work at Fortune 500 companies has given me deep experience in translating complex technical requirements into scalable, maintainable solutions that stakeholders actually use. - 𝐂𝐨𝐫𝐞 𝐄𝐱𝐩𝐞𝐫𝐭𝐢𝐬𝐞 𝐆𝐞𝐧𝐞𝐫𝐚𝐭𝐢𝐯𝐞 𝐀𝐈 𝐚𝐧𝐝 𝐋𝐋𝐌 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 I specialize in building custom LLM applications tailored to specific business needs. This includes fine-tuning large language models, implementing RAG architectures for knowledge-grounded responses, and developing conversational AI systems that handle nuanced, domain-specific queries. I have hands-on experience with OpenAI, Anthropic, LLaMA, Mistral, and other leading foundation models. 𝐀𝐈 𝐀𝐠𝐞𝐧𝐭 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 I design and build autonomous AI agents capable of reasoning, planning, and executing complex multi-step tasks. My agent implementations leverage frameworks like LangChain, LlamaIndex, and CrewAI to create systems that can browse the web, interact with APIs, process documents, and make intelligent decisions with minimal human intervention. 𝐕𝐨𝐢𝐜𝐞 𝐀𝐈 𝐒𝐨𝐥𝐮𝐭𝐢𝐨𝐧𝐬 I develop end-to-end voice AI applications including speech-to-text, text-to-speech, and real-time conversational voice agents. My experience covers integration with platforms like ElevenLabs, Whisper, and custom voice synthesis pipelines for natural, human-like interactions. 𝐅𝐮𝐥𝐥 𝐒𝐭𝐚𝐜𝐤 𝐀𝐈 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧 I build complete AI-powered applications from frontend to backend. This means designing intuitive user interfaces, developing robust APIs, managing vector databases, and orchestrating ML inference pipelines. I ensure that AI capabilities are not just technically sound but also accessible and performant for end users. 𝐂𝐨𝐦𝐩𝐮𝐭𝐞𝐫 𝐕𝐢𝐬𝐢𝐨𝐧 𝐚𝐧𝐝 𝐏𝐫𝐞𝐝𝐢𝐜𝐭𝐢𝐯𝐞 𝐀𝐧𝐚𝐥𝐲𝐭𝐢𝐜𝐬 My background includes extensive work in computer vision for manufacturing defect detection, predictive maintenance modeling, and real-time anomaly detection systems. I apply statistical rigor and domain expertise to build models that deliver measurable improvements in quality and efficiency. 𝐃𝐚𝐭𝐚 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠 𝐚𝐧𝐝 𝐌𝐋𝐎𝐩𝐬 I architect scalable data pipelines and ML infrastructure that support rapid experimentation and reliable production deployment. From ETL workflows to model monitoring and CI/CD for machine learning, I ensure that AI systems remain accurate, efficient, and maintainable over time. - 𝐓𝐞𝐜𝐡𝐧𝐢𝐜𝐚𝐥 𝐒𝐤𝐢𝐥𝐥𝐬 𝐋𝐚𝐧𝐠𝐮𝐚𝐠𝐞𝐬: Python, JavaScript, TypeScript, SQL, R, Bash 𝐌𝐚𝐜𝐡𝐢𝐧𝐞 𝐋𝐞𝐚𝐫𝐧𝐢𝐧𝐠 𝐚𝐧𝐝 𝐀𝐈: PyTorch, TensorFlow, Scikit-learn, Hugging Face Transformers, OpenAI API, Anthropic API, LangChain, LlamaIndex, CrewAI, AutoGen 𝐆𝐞𝐧𝐞𝐫𝐚𝐭𝐢𝐯𝐞 𝐀𝐈 𝐚𝐧𝐝 𝐋𝐋𝐌: GPT-4, Claude, LLaMA, Mistral, Fine-tuning, Prompt Engineering, RAG, Vector Embeddings, Semantic Search 𝐕𝐨𝐢𝐜𝐞 𝐀𝐈: Whisper, ElevenLabs, AssemblyAI, Deepgram, Real-time Voice Agents 𝐃𝐚𝐭𝐚 𝐚𝐧𝐝 𝐃𝐚𝐭𝐚𝐛𝐚𝐬𝐞: PostgreSQL, MongoDB, Pinecone, Weaviate, ChromaDB, Redis, Snowflake, BigQuery 𝐅𝐮𝐥𝐥 𝐒𝐭𝐚𝐜𝐤 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭: React, Next.js, Node.js, FastAPI, Flask, Django, REST APIs, GraphQL 𝐂𝐥𝐨𝐮𝐝 𝐚𝐧𝐝 𝐃𝐞𝐯𝐎𝐩𝐬: AWS, GCP, Azure, Docker, Kubernetes, Terraform, GitHub Actions, MLflow, Weights and Biases 𝐃𝐚𝐭𝐚 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠: Apache Airflow, Spark, Kafka, dbt, ETL Pipeline Design, Data Modeling - 𝐖𝐡𝐚𝐭 𝐈 𝐃𝐞𝐥𝐢𝐯𝐞𝐫 When you work with me, you get more than just code. You get a strategic partner who understands how to align AI capabilities with your business objectives. I communicate clearly, meet deadlines consistently, and build solutions designed for long-term success rather than quick fixes. I am particularly effective at taking ambiguous requirements and turning them into well-defined, actionable plans. Whether you need a proof of concept to validate an idea or a production system ready to scale, I bring the technical depth and practical experience to make it happen. Let us build something intelligent together and turn your AI vision into a working solution that delivers real, measurable value for your business.
