Built full-stack platforms using React, Next.js, Node.js, TypeScript with
integrated Al/LLM modules
Designed and developed scalable full-stack platforms using React, Next.js,
Node.js, TypeScript integrated with production-grade AI/LLM systems.
Built intelligent AI assistants using OpenAI GPT models, LangChain, Retrieval-
Augmented Generation (RAG) pipelines, and semantic search for real-world
applications.
Architected high-performance backend systems using Node.js, Python
(FastAPI/Flask), and API frameworks (GraphQL, REST) with an emphasis on
scalability and maintainability.
Designed and maintained cloud-native infrastructure on AWS and GCP using
Docker, Kubernetes, Helm, Terraform, enabling high availability and
automated deployments.
Implemented monitoring and observability frameworks using Prometheus,
Grafana, Loki, and Alert manager to ensure reliability, performance visibility,
and proactive alerting.
Led system design reviews, code reviews, and security best practices to
enforce high-quality engineering standards and secure development
workflows.
Developed and maintained CI/CD pipelines using GitHub Actions and cloud
build tools for automated testing, deployment, and release management.
Actively managed repositories on GitHub, maintaining well-structured
codebases, pull requests, version control workflows, and collaboration across
teams using Git branching and issue tracking.
Enforced clean coding standards, documentation, and repository hygiene
through structured Git workflows, code review processes, and release
versioning strategies.
Enhanced intelligent assistants using OpenAI GPT models, LangChain, RAG,
semantic search
Designed scalable backend microservices using Node.js, Python, GraphQL,
REST
Architected distributed cloud environments on AWS/GCP using Docker,
Kubernetes, Helm, Terraform
Executed monitoring and observability: Prometheus, Grafana, Loki, Alert
manager
Performed code reviews, system design, security analysis, and CI/CD
implementations

Conducted in-depth code reviews across full-stack pull requests:
C#/.NET Core backend, Angular web components, stored procedures,
and async patterns, enforcing Repository/Command separation,
Cancellation Token propagation, and strict layering.
Enforced architectural standards including Repository interfaces,
Command composition (no direct DB access), ViewModel patterns,
HTTP verb semantics, and naming consistency from Controller to
Service to Command to Repository to Stored Procedure.
Reviewed and optimized complex SQL Server queries and stored
procedures, identifying performance issues (inline subqueries in joins,
missing indexes on temp tables, unfiltered aggregations) and promoting
temp table + index patterns.
Mentored team through constructive PR feedback, suggesting
refactorings for commands exceeding size/dependency limits,
decomposition opportunities, and technical debt reduction.
Validated Angular code for modern patterns: standalone components,
signals, inject(), takeUntilDestroyed(), and reactive forms in NX
monorepo environment.
Ensured REST API consistency, proper request/response modeling, and
adherence to established conventions across high-impact changes.
Contributed to architectural decisions and occasionally implemented
complex backend logic using NHibernate Query Over, mappings, and
session management.
Monitored production systems with structured logging (N Log
equivalent) and proactive alerting for reliability.
