I will build high performance real time user and admin dashboards
Anish
About this gig
Need a high-performance backend architecture or a live, real-time dashboard capable of processing high-currency data metrics with sub-millisecond lag?
I am a backend specialist and systems architect with 5+ years of experience engineering core financial frameworks and high-speed data applications (including automated quantitative trading systems). I specialize in high-concurrency Golang runtimes, WebSocket streams, Node.js, and heavily optimized PostgreSQL systems.
If your web stack is stalling due to data inflation, DOM overload, or slow queries, I am here to optimize it.
What I Offer:
High-performance backend engine development in Golang / Node.js
Low-latency real-time data streaming via native WebSockets
Reactive, fast data dashboards built with Next.js and Charting tools
Optimized complex queries & database connection pooling
Automated secure webhooks
Scalable deployment setups on cloud networks (Vercel / AWS / GCP / Railway)
Why Me?
1. True Concurrency: Expert level use of Go routines, channels, and mutexes.
2. Absolute Data Integrity: Secure, type-safe data validation setups.
Message me with your data pipeline specification sheets today!

FAQ
Why do you favor Golang for real-time backend systems?
Golang features native concurrency models (goroutines) and a compiled runtime, making it exponentially faster and more memory efficient than JavaScript for processing massive numbers of concurrent data feeds.
How do you guarantee low-latency real-time updates?
I engineer persistent bi-directional communication pipelines using raw WebSockets, avoiding inefficient HTTP polling architectures completely.
Can you handle live financial data feeds or trading exchange APIs?
Yes. I have extensive experience building multi-exchange REST/WebSocket pipelines for algorithmic trading suites requiring absolute precision.
How do you prevent UI freezing when rendering thousand of data ticks?
On the frontend (Next.js/React), I implement down-sampling layers, throttle state updates, and utilize canvas or optimized charting systems to prevent DOM lag.
What relational databases do you build systems on?
I highly prefer PostgreSQL or Supabase instances configured with strict indexing, connection pooling, and custom functions for processing large datasets.
Can you optimize an existing slow API backend?
Yes. I can profile your code, identify slow bottlenecks, refactor expensive database queries, and add memory caching layers like Redis to speed it up.
Do you build microservice systems or monolithic systems?
Depending on your infrastructure needs, I can design modular monolithic frameworks or distributed microservices communicating securely via gRPC or message queues.
Are your backend architectures secure against injection and threats?
Yes, I implement strict input sanitization, type validation, structured middleware authentication, and secure CORS/security policy parameters.
What cloud infrastructure setups do you support?
I deploy to AWS (EC2, RDS), Google Cloud Platform (GCP), or rapid containerized runner environments like Railway, Render, and Dockerized instances.
Do you provide complete technical documentation?
Every backend delivery includes a clean Readme, deployment setup instructions, structural architecture maps, and fully commented OpenAPI/Swagger specifications.
