Full-Stack Development
Expertise in building multi-tenant production platforms using React, TypeScript, Node.js, GraphQL, and PostgreSQL, covering both frontend and backend layers with a focus on scalability and performance.
AI / LLM Engineering
Hands-on experience integrating OpenAI and Anthropic APIs, LangChain, RAG pipelines, embeddings, and vector databases (Pinecone, Weaviate, FAISS) for frontier-model training and evaluation workflows.
Cloud & Distributed Infrastructure
Deep knowledge of AWS (ECS, EKS, Lambda, EC2, S3, RDS, CloudFront, CloudWatch), GCP (GKE, Cloud Run, Pub/Sub), Docker, Kubernetes, and Terraform for designing and operating distributed systems at global scale.
Machine Learning
Proficiency with PyTorch, scikit-learn, Hugging Face Transformers, NumPy, Pandas, and MLflow for model training, feature engineering, model evaluation, model serving, and drift monitoring.
Backend & API Design
Strong background in Node.js, NestJS, Express, FastAPI, tRPC, REST, and WebSockets for building high-performance, scalable backend services and APIs.
Observability & Monitoring
Experience with Datadog, Honeycomb, New Relic, Prometheus, Grafana, Loki, Sentry, and distributed tracing to ensure system reliability and performance visibility.
Data & Databases
Extensive use of PostgreSQL, Redis, MongoDB, MySQL, DynamoDB, Prisma, and Drizzle ORM for data modeling, query optimization, caching, and transactional consistency.
CI/CD & DevOps
Automation of deployment pipelines using Docker, GitLab CI, GitHub Actions, and Jenkins with zero-downtime canary and blue-green release strategies.
Engineering Leadership & Code Quality
Setting engineering standards through code review, technical mentoring, ESLint, Prettier, Husky, and TypeScript enforcement across teams to eliminate recurring rework.

Project history
Architected a multi-tenant digital product platform for enterprise clients using React, TypeScript, Node.js, GraphQL, PostgreSQL, Docker, and Kubernetes. Designed distributed backend for LLM training data-generation and evaluation workflows. Built OpenAI and Anthropic evaluation integrations with LangChain, shipped real-time evaluation dashboards, and set engineering standards across teams.
Designed distributed flag-delivery architecture with PostgreSQL, Redis caching, and Nginx load balancing. Optimized flag-evaluation APIs for sub-millisecond lookups at global scale. Built React, TypeScript, and GraphQL dashboards for progressive feature flag rollouts. Engineered WebSocket-based release monitoring and automated CI/CD pipelines with zero-downtime releases.
Built a distributed agent system in Python, Node.js, React, and PostgreSQL automating multi-step sales workflows. Developed ML model-serving infrastructure with FastAPI, PyTorch, and scikit-learn. Integrated OpenAI, Anthropic, and LangChain into a conversational CRM interface. Engineered multi-tenant GraphQL and PostgreSQL services and ran MLflow experiment tracking with automated retraining.
