Hello, I'm
Kushal Soni

While others debate whether AI will replace developers, I am busy shipping features that matter. Microservices, AI integrations, real-time systems — I have built them all. Grounded, collaborative, and focused on results.
What I Bring
More than just code
I bring solutions, not just implementations
AI-First Mindset for Scale
LLMs, RAG systems, AI agents – I integrate cutting-edge AI into practical, production-ready solutions.
Ship Fast, Ship Right
I believe in rapid iteration without sacrificing quality. From MVP to scale, I get things done.
Performance Obsessed
Every millisecond counts. I optimize ruthlessly – from database queries to frontend rendering.
Built to Scale
Architecture that grows with you. Microservices, event-driven systems, cloud-native solutions.
Expertise
Technical Stack
Full-stack depth across backend, infrastructure, and AI systems

Work History
Building impactful solutions across startups and enterprises
Product Engineer
- Shipped a multilingual AI voice agent with 300ms end-to-end latency using WebRTC streaming, integrating LLM-driven dialogue orchestration and open-source TTS models to automate lead qualification at scale; designed async pipelines to handle high-concurrency voice sessions reliably.
- Engineered an AI-powered image generation workflow by orchestrating multiple LLMs for composite visual outputs, delivering a production-grade FastAPI backend with background task processing and cloud storage integration, improving content turnaround time by 40%.
- Architected a highly available microservice for real-time pricing computation, processing 100k+ evaluations per day with < 120ms latency using asynchronous ingestion, rule-based resolution pipelines, and resilient fallback mechanisms.
- Owned full-stack lead capture tools including a Strapi powered CMS backend and a Next.js frontend, building SEO optimized websites, forms, and interactive demos using SSR, ISR, and SSG to deliver fast, user-friendly experiences.
Software Development Engineer
- Designed and owned backend APIs and domain models for core platform features including user inactivity tracking and globally configurable asset form modules; executed zero-downtime data migration for 30k+ active users.
- Improved platform performance by introducing Redis caching layers, optimizing relational schemas, and tuning MySQL indexes, resulting in a 1.5× reduction in critical API response times and improved system stability under load.
- Built and optimized frontend application architecture using Redux, memoized selectors, debounced inputs, and robust form validation to reduce redundant API calls, improve UI responsiveness by 25%, and enhance overall user experience.
- Implemented secure file-sharing workflows with role-based access controls and extensible REST APIs, supporting multiple delivery and permission models across enterprise customers.
- Established centralized logging and observability pipelines processing 1M+ events per day, integrating Grafana dashboards to support performance monitoring, benchmarking, and proactive incident detection.
Junior Software Development Engineer
- Built backend-driven internal tools including multi-level approval workflows, role-based access control, localization support, and referral tracking systems, contributing directly to platform scalability and governance.
- Developed a scalable notification system with template-driven messaging and timezone-aware scheduling, enabling non-technical teams to manage 300+ notification templates independently.
- Implemented feature flags, A/B testing, and event tracking to support data-driven experimentation, accelerating safe feature rollouts by 50%.
- Designed reusable frontend UI components and user interaction flows for audio and video recording, feedback collection, and in-app security mechanisms, closely integrating frontend experiences with backend services.
Portfolio
Featured Projects
A selection of work I'm proud of
Orchestra Engine
A self-hostable, open-source Distributed Job Scheduler & Workflow Engine built in TypeScript. Orchestra Engine solves the coordination problem every backend team eventually hits — multi-step workflows that chain sequentially, fan out in parallel, retry intelligently on failure, and never lose a job across crashes or scaled replicas. It ships with declarative workflow definitions, a dead-letter queue with one-click replay, cron scheduling with full audit history, and a live dashboard streaming.

Insights on AI, backend engineering, and building things that matter
Distributed Transactions in Microservices: Why Consistency Gets Complicated Fast
Distributed transactions sound straightforward in theory: multiple services should either succeed together or fail together. In practice, things become messy very quickly. Network failures, retries, partial commits, and service crashes make consistency one of the hardest problems in distributed systems. This post takes a deep dive into distributed transactions, why traditional approaches struggle in microservices, and how Two-Phase Commit and Saga patterns behave in real production systems.

When RabbitMQ Notifications Go Wrong: The Production Failures No One Warns You About
Sending notifications with RabbitMQ looks simple — publish a message, consume it, send email or push. But under real traffic, retry storms, duplicate sends, ordering issues, and dead-letter queues start appearing. This post breaks down what actually goes wrong and how production systems handle it.</p>
Services
What I Build
End-to-end development across backend, AI, and full-stack systems
Backend Engineering
Robust backend systems that scale. Node.js, Python, PostgreSQL, Redis based secure APIs, auth, and third-party integrations.
AI Integration
Practical AI solutions – chatbots, content generation, RAG systems, AI agents. Production-ready and cost-optimized.
DevOps & Cloud
I build deployment pipelines and cloud infrastructure that scale with your product. From Dockerized apps and CI/CD to monitoring, alerts, and auto‑scaling—your systems stay fast, stable, and easy to ship.
