Developer - Project: BloomSocial (Social media management platform) - VisionX Technologies (2025-04) - Built the service layer for LinkedIn and Instagram API integrations, including centralized error handling, standardized response objects, and structured logging to handle provider-specific failures, token expiration, and retry scenarios.

• Built a Retrieval-Augmented Generation (RAG) pipeline using pgvector (PostgreSQL) for embeddings and semantic search, grounding AI-generated post copy and captions in brand-specific context and past content.
• Implemented JWT-based authentication for social channel integrations and secure payment gateway access, with webhook-based asynchronous event handling.
• Designed distributed backend workflows for scheduling, analytics, and event-driven processing with optimized SQL queries — handling 200+ scheduled posts/day across 7+ connected social channels - Partner with the founder to break down feature requests into technical specs, coordinate with the frontend engineer on API contracts, and triage priorities across two concurrent products — flagging blockers and providing status updates directly to leadership.

Developer - Project: BullTrek — Multi-Asset Algorithmic Trading Platform (Crypto + Indian Stocks) - VisionX Technologies - Architected a stateful strategy engine (Strategy Runtime + Runtime Registry) supporting 8 concurrent strategy types — Smart Grid, Growth DCA, UTC (UT Bot + Schaff Trend Cycle), Indy Trend (Supertrend + RSI + ADX), LESI (EMA + Williams RSI), and Price Action — processing live market ticks and candle-close events in real time.

• Built a volatility-adjusted Smart Grid system combining ATR, Annualized Volatility, Bollinger Bands, and Support/Resistance detection to auto-calculate optimal grid levels across 3 configurable risk profiles (Safe, Neutral, Risk).
• Integrated 6 trading venues — 3 crypto exchanges (Binance, KuCoin, CoinDCX) and 3 Indian stock brokers (AngelOne, Zerodha, Kotak) — behind a unified Trade Dispatcher supporting LIVE, PAPER, and BACKTEST execution modes.
• Built a real-time market data layer (Socket.io + native exchange WebSockets) routing live ticks to active strategies, with a separate socket layer pushing state updates to the frontend.
• Implemented JWT authentication with optional TOTP 2FA and encrypted per-exchange API credentials across a relational Prisma/PostgreSQL schema tracking users, strategies, orders, trades, and isolated paper-trading balances.
