Production Architecture & Systems
High-signal engineering deep-dives into data lifecycles, real-time synchronization, and architectural trade-offs.
Riska (Automated Trading)
A strategy-based automated trading engine for Nifty 50 assets.
- Dynamic config for 50+ instruments
- Real-time P&L Action Drawer
- Consolidated P&L insights & heatmaps
Log: System Sequence
Stale UI states and race conditions during high-frequency volatility, completely breaking execution tracking if WebSocket drops.
Implemented a hybrid Polling + WebSocket reconciliation loop. Polled data serves as the baseline truth while WebSockets mutate immediate states, maintaining sub-100ms sync.
iYurek & Trading Views (AI-Powered)
Multi-asset financial analytics with AI-powered sentiment and RRG views.
- Pixel-perfect Figma-to-Code migration
- Interactive card-based metrics
- Decoupled rendering for lag-free charts
Log: System Sequence
The live Sentiment Meter's simulation logic was unstable, with calculation timers resetting on every state update, causing data stalls.
Architected a stable simulation bank using useRef for ticker data isolation, decoupling numerical calculation from the React render lifecycle.
APOCR (AI Invoice System)
Automated invoice ingestion with AI-driven reasoning and validation.
- Pending/Done/Rejected classification
- Vendor data auto-mapping
- Accelera domain redirection flow
Log: System Sequence
Machine learning OCR output returned deeply nested, highly inconsistent JSON bounding-box coordinates impossible to map to UI models.
Engineered a normalization layer in Redux Toolkit. Built a visual synchronization algorithm using relative DOM positioning natively over the PDF.
Daily Tools 100+ Micro-App Architecture Experiment
A production-scale system of 100+ client-side developer tools, formatters, and micro-games built to explore AI-assisted architecture and massive client-side state synchronization.
Log: System Sequence
Astro's SSR build failed against browser-native APIs (Monaco Editor, canvas) used across 100+ tools, and managing state synchronization across devices without traditional authentication proved high-friction.
Enforced flawless SSR resilience via dynamic imports and strict 'client:only' React boundaries. Architected 'Matrix Pulse', a hybrid local-first sync engine that silently mirrors user states to the cloud via background React lifecycles.
Last Man Standing Prediction-Based Elimination System
A logic-driven prediction and elimination system where users progress through rounds based on match outcomes, similar to high-stakes fantasy league mechanics.
Log: System Sequence
Managing complex, round-dependent state transitions and automated user elimination logic without traditional heavy authentication friction.
Engineered a robust state engine that handles token-based user identifying and automated round progression. Built an admin-controlled workflow for match result declaration that triggers synchronous rank updates and elimination across the entire pool.
