A cryptocurrency tracking system monitors, analyzes, and displays real-time data on digital assets, including prices, market capitalization, and portfolio performance across exchanges and wallets. These systems utilize blockchain APIs (like CoinGecko) and manual inputs or API keys to track transaction history, calculate profit/loss, and assist with tax compliance. Key tools include apps like CoinStats, Koinly, and CoinTracker, alongside blockchain explorers like Etherscan.
Emotion recognition from speech (SER) uses machine learning to analyze vocal patterns (pitch, tone, energy) to classify human emotions like happy, sad, or angry, enabling empathetic human-computer interaction, improving customer service, and enhancing smart applications, though it's challenging due to emotional ambiguity and requires robust feature extraction from audio signals.

Detailed profile
Creative and results-driven Full-Stack Developer with 5+ years of hands-on experience designing, building, and shipping production web applications. I bridge product thinking and engineering discipline to deliver polished front-end experiences and reliable, well-tested back-end systems. I enjoy turning ambiguous requirements into clear technical plans, shipping frequently, and improving products through data and user feedback.
I’ve led technical design and implementation for consumer and B2B web apps — from concept through deployment and monitoring. My focus is on maintainable code, fast and accessible user interfaces, and back-end systems that scale. I pair strong fundamentals (data structures, algorithms, system design) with modern frameworks and cloud services to deliver business value quickly.
Marketplace Platform — Architected a two-sided marketplace using Next.js + GraphQL and Node microservices. Implemented real-time notifications and payments; optimized page load time to sub-1s Largest traffic spike: 20k concurrent users during launch week.
Internal Analytics Dashboard — Built a secure, role-based analytics suite for operations using React + Django REST, efficient caching with Redis, and automated ETL pipelines. Reduced manual reporting time from days to minutes.
SaaS Onboarding Flow — Rewrote onboarding flow and billing integration; improved 30-day activation by 22% and reduced churn through targeted experiments.
Why I add value
I combine strong product empathy with pragmatic engineering: I care about end-user experience, developer ergonomics, and operational reliability equally. I prioritize shipping small, testable increments, measuring impact, and iterating. I communicate clearly with PMs and designers, lead code discussions, and mentor teammates to raise overall engineering quality.
Looking for
Opportunities where I can own features end-to-end, contribute to architecture decisions, and help scale a product and team. Open to full-time roles, contract work, and startup collaborations.
