Full Stack Web & Mobile Development
Expertise in building responsive web interfaces with React, Angular, and Vue.js, as well as cross-platform mobile applications using React Native and Flutter, covering both iOS and Android deployment.
AI / ML Integration & Automation
Proficiency in integrating AI/ML models into production systems using Model APIs (FastAPI, Flask), real-time inference, vector databases (Pinecone, Milvus), ML Pipelines, LangChain, RAG Architectures, and Workflow Automation.
Backend Development & Microservices
Strong background in building robust backend microservices with Java (Spring Boot, Spring MVC, Hibernate), Python, and Node.js, including RESTful APIs, GraphQL, and high-performance database optimization with PostgreSQL, MongoDB, MySQL, Redis, and Firebase.
Cloud & DevOps
Hands-on experience with AWS (EC2, S3, RDS, Lambda), Docker, Kubernetes, and CI/CD pipelines using Jenkins and GitHub Actions, enabling zero-downtime deployments and automated rollbacks.
Frontend Technologies
Solid command of TypeScript, HTML5, CSS3, Tailwind CSS, Material UI, and Bootstrap for building polished, user-centric frontend interfaces.
Agile & TDD Methodologies
Application of Agile/Scrum, Test-Driven Development (TDD), Event-Driven Architecture, and Performance Tuning to ensure high code quality and rapid iteration cycles.
Serverless & Infrastructure Automation
Implementation of serverless AWS Lambda functions to automate infrastructure scaling based on real-time usage patterns and streamline deployment processes across multiple environments.
Real-Time Systems & WebSocket Communication
Design of low-latency WebSocket communication for streaming sensor and infrastructure data, as well as real-time anomaly detection and alert automation for enterprise IT systems.

Project history
Designed and built end-to-end AI-powered web and mobile applications with React/TypeScript dashboards and React Native mobile clients. Automated IAM workflows using AI-driven rule engines, developed cross-platform mobile SDKs with real-time AI inference, engineered high-performance backend services with Java (Spring Boot) and Node.js supporting 100K+ concurrent users, and built CI/CD pipelines on AWS with Docker and Kubernetes.
Delivered full-stack solutions for cryptographic key sharing and hardware-to-software validation. Developed cross-platform mobile prototypes using Flutter and React/Redux SPAs, integrated AI-driven automation pipelines for cryptographic transaction monitoring, optimized backend APIs with Java and Python (FastAPI), and implemented serverless AWS Lambda functions for infrastructure scaling.
Built customized digital transformation frameworks and backend optimization solutions for enterprise clients, integrating Angular frontends with Java microservices. Developed hybrid mobile application prototypes using Flutter, automated data pipelines and monitoring workflows with Redis and MongoDB, and implemented TDD and Agile methodologies.
