UI State Tree

World Cup 2026 Dashboard — real-time tournament telemetry for BST timezone

Frontend Architect & State Engineer

A localized FIFA World Cup 2026 dashboard optimized for real-time tournament telemetry. Features dynamic schedule mutation engines converting raw UTC match fixtures into Bangladesh Standard Time (BST) with zero layout shift. Engineered as Step 1 of an explicit 5-stage architectural pipeline, completely decoupling the rendering layer using a verified mock data engine to validate state changes and structural UI fidelity before backend cutover.

Zustand store modeled around normalized match/fixture entities to avoid prop-drilling across the schedule grid.
Mock data layer mirrors the exact shape of the planned backend response, so swapping in the live API requires zero component changes.
BST conversion handled at the data layer, not in components — every view reads already-localized timestamps.

PostgreSQL

Tournament Telemetry Core — high-concurrency asynchronous match engine

Backend Infrastructure Engineer

An asynchronous FastAPI backend engine built to orchestrate and serve live tournament states across 7 comprehensive REST API modules. Implements rigid relational schemas inside PostgreSQL with Alembic migrations for zero-downtime structural database versioning. Features an aggressive Redis caching tier deployed to offload heavy read traffic from the primary database during transactional match telemetry spikes, coupled with a deterministic data-seeding framework aligned with the frontend mock schema.

Alembic migrations version-controlled independently from application code for safer, revertible schema changes.
Redis applied selectively as a cache-aside layer on read-heavy endpoints only, avoiding stale-write risk on live score updates.
Seed data generated deterministically from fixed fixture IDs, so frontend and backend teams test against identical data.

LLM Evaluator

PyQuiz Pro — sandboxed automated code evaluation and recruitment platform

Full-Stack Engineer & AI Integrator

A premium, enterprise-grade technical assessment platform engineered with a high-fidelity cyber-dark aesthetic for automated candidate evaluation. The application orchestrates a high-performance evaluation runtime: a sandboxed Python FastAPI execution pipeline for instant code parsing, coupled with an LLM-driven AI recruitment analyst framework. Delivers sub-second evaluation loops checking code control structures, recursive loop blocks, and operational logic validation while outputting structured predictive fit scores.

Each code submission runs in an isolated sandboxed process, preventing cross-contamination between candidate runs.
LLM evaluation prompts are rubric-driven rather than open-ended, keeping scoring consistent across repeated runs.
Static analysis runs before the LLM call, so obviously invalid submissions never consume a model invocation.

Queue Plane

Distributed Media Engine — global scale system architecture matrix

Systems Architect (Case Study)

A comprehensive architectural framework addressing the system design patterns required to sustain a highly scalable, distributed photo and video-sharing ecosystem. Focuses on balancing performance, horizontal scalability, and multi-region fault tolerance across two high-impact operations: a secure, low-latency session validation architecture for global authentication, and an isolated media delivery pipeline utilizing multi-tier edge CDN networks, geo-distributed caching grids, and stateless image-processing queues.

Session validation designed stateless-first (signed tokens over server-side sessions) to support horizontal scaling without sticky sessions.
Read/write ratios modeled explicitly to justify a CDN-first caching strategy over deeper application-layer caching.
Image pipeline treated as an independent scaling unit from the core API, so media spikes never starve request handling.

NoSQL Storage

Real-Time Messaging Fabric — persistent distributed WebSocket connection cluster

Distributed Systems Engineer

An architectural system blueprint for an enterprise-grade instant messaging core engineered to route billions of concurrent transactional updates with sub-second delivery loops. Implements persistent WebSocket connection planes behind reverse-proxy load balancers to maintain active user states, backed by a horizontally partitioned NoSQL storage layer for persistent message logging. Mitigates high-concurrency race conditions through message-queue backpressure layers, dead-letter routing, and out-of-order sequence reconciliation engines.

Per-message sequence numbers support client-side out-of-order reconciliation without extra server round-trips.
Dead-letter queue paired with exponential backoff isolates poison messages instead of blocking healthy throughput.
Connection state kept out of application memory, so any gateway instance can restart without dropping client sessions.

MongoDB

Bookstore — full-CRUD MERN inventory & storefront

Full-Stack Developer

A complete MERN-stack bookstore application supporting the full create-read-update-delete lifecycle for inventory. Users browse, add, edit, and remove book listings in real time, with a Stripe-integrated checkout flow handling purchase transactions end-to-end.

Full CRUD flow (create, post, edit, update, delete) implemented across both the storefront and an admin-facing view.
Stripe integrated directly into the checkout path for handling real payment transactions.
Firebase used alongside MongoDB for auth and supplementary storage needs.

Vanilla JS UI

This Portfolio — the site you're looking at right now

Designer & Developer

A dependency-free personal site built in plain HTML, CSS, and JavaScript — no framework, no build step. One CSS custom-property system drives the entire dark/light theme, while vanilla JS handles the interactive timeline, expandable technical drawers, and scroll-triggered reveal animations.

Entire dark/light theme driven by a single set of CSS custom properties — no duplicated styles per theme.
IntersectionObserver powers the scroll-reveal animations without any external animation library.
Zero build tooling: what ships in the browser is the source file itself, deployed as-is.
