Description

I am an AI Engineer with a hybrid focus: I combine software architecture (Full Stack) with 14 years of experience in signal processing and audio.

My differentiator is both technical and creative: I apply the discipline of audio engineering: signal management, structured/unstructured data, and flow precision to build reliable data pipelines, optimize inference latency, and fine-tune models.

I understand that data acts as a complex signal (voice, video, text) requiring specific treatment. I design multimodal systems and automations that understand the nature of creative content to solve real business problems.

PROFESSIONAL IMPLEMENTATIONS

Enterprise Workflow Automation: Engineered automation infrastructure for high-volume content operations.

*Workflow Logic: Built modular n8n + Python frameworks to automate linguistic scoring and dataset integration.

*Data Exploration: Deployed dynamic query systems turning JSON schemas into SQL, allowing teams to query data without writing code.

*Governance: Implemented LLM-based logic gating to validate content against legal rubrics before shipping.

Media AI & RAG Systems Engineered AI-dubbing and search tools for large-scale EdTech platforms.

*AI Dubbing: Built a scalable pipeline (Voice Cloning + Lip Sync) to automate content localization into multiple languages.

*Semantic Search: Implemented LangChain + FAISS RAG pipelines over 300+ scripts for instant asset retrieval.

*Orchestration: Deployed Dockerized FastAPI services to chain Text-to-Speech (TTS) microservices.

Agentic Systems

*Designed autonomous Multi-Agent Systems using LangGraph to transform LLM outputs into executed business actions.

*Fine-tuned models using iterative feedback loops to improve accuracy in production environments.

Designed RAG-based knowledge-base systems for company documentation, including source selection, metadata strategy, chunking logic, retrieval scope, and answer traceability.

Helped non-technical appliedAI users adopt AI tools by designing guided workflows, reusable Claude skills, and internal enablement patterns that reduce dependency on engineering support.

Built enterprise-safe AI workflows with scoped retrieval, source attribution, data-leakage prevention, GDPR-conscious design, and controlled tool use.

Built internal AI agent products for appliedAI teams, using real operational workflows as validation environments before adapting proven patterns for enterprise client delivery.

Supported internal AI enablement by translating technical agent capabilities into practical tools that consultants, delivery teams, and business users can apply directly in their daily workflows.

• ● Engineered modular n8n+Python frameworks combining LLM calls, prompt templates, NLP scoring and data-visualization
pipelines to automate linguistic scoring, dataset integration and insight generation at scale.
• ● Developed dynamic query systems that turn JSON schemas into SQL plus LLM-based reasoning, exposing self-serve data
exploration and research-style insights for non-technical teams.
• ● Automated content workflows via n8n-orchestrated pipelines (Drive ,Vision,OCR,Sheets), with APIs, QC flags & reports with error-tolerant flows so processes run without manual work.
• ● Systematized brand-tone governance by using LLMs and structured rubrics to check copy against editorial, legal and UI rules,
acting as a review agent that flags issues before content ships.
• ● Ran structured A/B tests on system and user prompts across languages, improving answer relevance, reducing hallucinations and
keeping tone on-brand.
• ● Standardized prompt libraries around GPT-5/Claude-style models with logging and best-practices docs, making LLM automations traceable and reusable across teams.
