AI / ML Engineering & LLM Integration
Expertise in building LLM-powered applications and retrieval-augmented generation (RAG) pipelines using LangChain, vector databases (pgvector, Pinecone), embeddings, prompt engineering, and AI workflow automation. Integration and orchestration of LLM APIs into production workflows, automating large portions of previously manual operations.
Backend Engineering & Microservices
14+ years of experience designing and shipping scalable, cloud-native backend systems using Node.js, TypeScript, C#, and .NET. Proficiency in building RESTful and GraphQL APIs, microservices architectures, and data-processing pipelines across energy, fintech, insurtech, and IoT domains.
Cloud Infrastructure & DevOps (AWS / CI/CD)
Deep experience deploying and operating services on AWS (EKS, Lambda, serverless, CloudFormation, DynamoDB) with a strong focus on CI/CD automation using GitHub Actions, Docker, Kubernetes, and Bamboo. Infrastructure-as-code practices reducing deployment times significantly in production environments.
Database Engineering
Hands-on experience with a wide range of databases including PostgreSQL, SQL Server, MySQL, MongoDB, DynamoDB, and Redis, covering both relational and NoSQL paradigms in high-throughput production systems.
Frontend Development
Practical knowledge of frontend technologies including React, Angular, AngularJS, Ionic, HTML, and CSS, enabling full-stack contributions across web and mobile projects.
Messaging & Event-Driven Architecture
Experience with messaging and integration technologies such as RabbitMQ, WSO2, n8n, and event-driven architecture patterns for building resilient, decoupled distributed systems.
Security, Compliance & AML/KYC
Development of business logic for AML, KYC, risk-scoring, and continuous-monitoring workflows, applying security, data-protection, and compliance best practices for systems handling real-time data.
Testing & Tooling
Proficiency with testing frameworks and tooling including Jest, Mocha, and version control platforms such as GitHub, GitLab, and Bitbucket, supporting high code quality and reliable delivery pipelines.
Team Leadership & Agile Practices
Experience leading cross-functional engineering teams in distributed, multi-country environments using Agile/Scrum methodologies, with a focus on observability, mentoring, and full lifecycle ownership from MVP to production.

Project history
Founded and led the engineering of TikTopia, an early-stage AI-driven startup for creator and campaign management. Designed scalable backend architecture and AI automation pipelines from MVP to production. Built LLM-powered features and RAG pipelines with LangChain and vector databases, cutting campaign-analysis time by ~40%. Integrated and orchestrated LLM APIs into product workflows, automating ~60% of previously manual campaign operations.
Built and maintained backend microservices for the Demand & Response platform, enabling dynamic load management of 200+ distributed photovoltaic plants. Deployed and operated services on AWS EKS sustaining 99.9% availability for real-time energy dispatch. Designed API integrations and data-processing workflows for real-time energy monitoring. Implemented automation to optimize load balancing, cutting dispatch response time by ~30%.
Designed and built scalable backend services and RESTful APIs for the CleverChain compliance platform. Implemented data-ingestion pipelines integrating registries, third-party providers, and blockchain data sources, processing millions of records daily. Developed business logic for AML, KYC, risk-scoring, and continuous-monitoring workflows. Partnered with AI/ML teams to integrate predictive risk-analysis models, reducing false positives by ~25%.
