About Me
I am a Senior Fullstack Engineer with a deep specialization in high-concurrency backend API engines, database performance optimization, and containerized cloud infrastructure.
Instead of fragmenting product delivery across separate frontend, backend, and DevOps teams, I design and ship complete end-to-end web applications—from pixel-perfect Next.js/React interfaces to robust Node.js/Python microservices, optimized PostgreSQL databases, and automated Kubernetes/Docker cloud deployments.
Core competencies include Next.js 16, React 19, Node.js/Express/NestJS, Python (FastAPI/Django), Go, PostgreSQL indexing & query optimization, Redis caching, gRPC/REST APIs, Docker, Kubernetes (K3s/EKS), GitHub Actions CI/CD, and Prometheus/Grafana observability.

✦Verified B2B Case Studies & Quantified Results
Case Study 1: Building a High-Throughput Fullstack SaaS Platform with Next.js & Node.js
Architected a multi-tenant B2B SaaS web application end-to-end. Built an interactive React 19 interface coupled with a Node.js REST backend, PostgreSQL storage layer, S3 media management, and automated GitHub Actions deployment pipelines.
- Designed responsive frontend UI components in Next.js 16 with instant client-side transitions and dynamic state management.
- Implemented secure JWT authentication with role-based access control (RBAC) and HTTP-only cookie security.
- Containerized the entire stack into Docker images and deployed to a multi-node Kubernetes cluster with zero downtime.
Case Study 2: Reducing P95 API Latency from 2.5s to 180ms for 15M+ Database Records
Peak hour traffic was causing severe API slowdowns on a 15-million row PostgreSQL database. By replacing inefficient N+1 query loops with composite B-Tree indexes, Redis Cache-Aside layers, and PgBouncer connection pooling, response times dropped dramatically.
- Identified unindexed foreign key lookups causing full sequential table scans on 15M rows.
- Added targeted B-Tree indexes and Redis distributed caching for read-heavy API endpoints.
- P95 latency dropped from 2,500ms to 180ms while database CPU load dropped from 85% to 18%.
Case Study 3: Automating Zero-Downtime Releases with ArgoCD GitOps & Security Gates
Manual deployment scripts caused deployment drift and release risk. We implemented a declarative GitOps continuous delivery pipeline using ArgoCD, Helm, and automated Trivy container vulnerability scanning in GitHub Actions.
- Standardized all application and infrastructure manifests inside version-controlled Git repositories using Helm.
- ArgoCD automatically reconciles drift within 30 seconds and executes automated rollbacks if readiness probes fail.
- Enforced least-privilege security policies and distroless Docker container builds for enterprise compliance.
