Isha Patel

Backend Developer with 3+ years building high-throughput financial and AI-driven systems in Node.js, Go, and TypeScript. Shipped production systems processing real-time crypto portfolio data at scale, reduced external API calls, and delivered end-to-end features across NestJS, Go/Fiber, and AWS-native stacks.

Software Developer at NeoSoft (2025-05 – Present)

Project: India Crypto Research (ICR)

• Engineered a FIFO-based crypto tax engine in Go, using goroutines for concurrent transaction processing across 48k+ datasets — with exportable PDF/CSV reports and non-blocking execution.
• Built a real-time portfolio tracker aggregating holdings from 5+ exchanges, delivering live PL updates with < 200ms latency — designed for consistent reads under concurrent user load using Redis.
• Designed a centralized data aggregation layer that cut external API calls by ∼90%. (3,420 → <200/request), reducing end-to-end system latency and significantly lowering third-party rate-limit exposure.
• Developed scalable, low-latency REST APIs in Go (Fiber) with PostgreSQL, ensuring efficient data access patterns for real-time analytics and high-throughput workloads.
• Engineered resilient data ingestion pipelines integrating 4 external providers (DefiLlama, CoinMarketCap, Token Terminal, Binance) with rate limiting, retries, timeouts, and fallback strategies to maintain high system availability under failures.
• Implemented Redis-based caching with TTL-driven eviction, significantly reducing redundant DB/API calls and improving system throughput and response times.
• Collaborated in agile product teams, owning features end-to-end from design to deployment, contributing to iterative releases and production stability using Azure.

Node.js Developer at DecodeUp Technologies (2025-01 – 2025-04)

Project: GROUPOS

• Architected a scalable large-file upload system using AWS S3 Multipart Upload with stream-based processing in Node.js, eliminating memory bottlenecks and enabling resumable, fault-tolerant uploads.
• Designed and implemented tier-based access control for modular content delivery, ensuring secure, scalable feature gating across user plans.

Software Developer at Par Solution (2023-06 – 2024-11)

AI-driven backend development for content generation and speech synthesis

• Architected and deployed scalable backend APIs integrating OpenAI, AWS Polly, Google TTS, and Speechify for AI-driven speech synthesis with multi-format audio export.
• Built dynamic voice preview functionality across multiple TTS models, enabling configurable voice selection and real-time comparison.
• Contributed to core backend services for an AI content generation platform integrating OpenAI, Hugging Face, and other third-party APIs for text-to-image, video, and audio generation.
• Improved backend performance by refactoring complex queries into optimized stored procedures, reducing CPU usage and lowering response latency under high traffic.

Software Developer Intern at Bildemp (2022-01 – 2022-06)

NestJS backend development and payment integration

• Built NestJS backend services for automated test generation and implemented Razorpay subscription integration with database schema design.

Bachelor's Degree in Computer Engineering – Vishwakarma Government Engineering College (2018 – 2022)
