Capabilities

Technical depth across
the full stack.

Five production languages. Carrier-grade telecom protocols. Our own Tier-3 data center on AS 64005. Every capability on this page is backed by a KaritKarma product that ships in production today.

Definition

What does LoneSock cover?

LoneSock's capability stack covers everything required to ship a modern enterprise system end to end: backend services in Go, .NET 10, and Rust, AI/ML pipelines in Python, frontends in Next.js and React 19, mobile in React Native and Dart, and infrastructure on our own Tier-3 data center.

Carrier-grade protocols (SIP/RTP/SRTP/WebRTC, SIGTRAN/SS7, RADIUS), security standards (OAuth 2.1, OIDC, PKCE, WebAuthn, FIDO2), and financial controls (ISO 20022, KYC/AML) are already in production across the KaritKarma platform.

Languages and frameworks

Production code in
five languages.

We pick the right tool for the job. Go and .NET for business logic and microservices, Rust for systems and carrier-grade workloads, Python for AI/ML, and Next.js for everything web.

Go

  • BizRP ERP (15 microservices)
  • ISPChamp OSS/BSS
  • GlobalView geospatial intelligence
  • Wenme OAuth 2.1 identity

Rust

  • BitsPath Voice PBX (~517K LOC)
  • IntraPay sovereign payment switch
  • SIP/RTP/SRTP/WebRTC stack
  • SIGTRAN/SS7 SMS gateway

.NET 10

  • BitsPath CPaaS platform
  • QRID club network platform
  • Kuhok film industry network
  • Sotto AI voice ordering (UK)
  • Rating, Boooks, Exit.bd, Hold.bd

Python

  • NewsForge autonomous newsroom pipeline
  • Boooks CLIP embeddings
  • Aegis fraud detection ML
  • pgvector semantic search

TypeScript / Next.js

  • All frontends (React 19)
  • Tailwind CSS 4 design systems
  • Turborepo monorepos
  • Server Components, SSG, SSR

Protocol expertise

Deep protocol
knowledge.

We have shipped real telecom, real identity, and real financial software. These are not buzzwords on a slide, they are running in production behind banks, ISPs, and newsrooms.

Telecom

  • SIP/RTP/SRTP/WebRTC
  • SIGTRAN/SS7
  • RADIUS AAA

Security

  • OAuth 2.1 / OIDC / PKCE
  • WebAuthn / FIDO2
  • RS256 / EdDSA JWTs

Financial

  • ISO 20022
  • PCI DSS Level 1 patterns
  • KYC / AML compliance

Infrastructure

We own
the stack.

KaritKarma is an APNIC member with own IP blocks, BGP peering, and a Tier-3 data center in Dhaka with a Sirajganj DR site. Client workloads can run on KaritKarma infrastructure, on the client's own cloud, or in hybrid mode.

Own Tier-3 Data Center

APNIC member with ASN 64005, BGP peering, and own IP blocks. Not renting cloud, operating infrastructure.

Dual-Site Capability

Dhaka primary plus Sirajganj DR for sovereign payment infrastructure. Active-active anycast over AS 64005.

Database & Messaging

PostgreSQL 18, RabbitMQ with MassTransit, Kafka, Redis. Production-proven across KaritKarma's 22-product ecosystem.

Container Orchestration

Docker Compose for development, CapRover and Kubernetes for production, Traefik reverse proxy, MinIO and R2 for object storage.

AI and machine learning

Not proofs of concept.
Production systems.

The AI workloads listed here process real customer traffic and real money. The patterns we apply on a client engagement are the same patterns running KaritKarma products in production today.

Production

Sub-500ms Voice AI

Sotto powers AI voice ordering for UK restaurants on .NET 10 and Groq Llama 4 Scout, with UK Big 14 allergen handling and GDPR-compliant transcripts.

Production

Autonomous News Pipeline

NewsForge orchestrates an 11-stage autonomous pipeline across ingestion, fact-check, drafting, and editorial workflows with human-in-the-loop approval.

Production

Real-Time Fraud Scoring

Aegis (AFTP) delivers behavioral analytics and anomaly detection for banks and mobile financial services in Bangladesh.

Production

Semantic Search and Embeddings

CLIP image embeddings on Boooks, pgvector similarity across Kuhok, and facial recognition inside Professional Vault.

Every capability on this page is backed by a production product in the KaritKarma ecosystem. See the full list of 22 products, tech stacks, and live URLs.

Frequently asked

Capabilities,
in plain language.

What does LoneSock build?

LoneSock builds production-grade backends, APIs, web frontends, mobile applications, AI pipelines, telecom systems, and payment infrastructure. The full-stack capability is anchored by Go, Rust, .NET 10, Python, and TypeScript, all of which ship in the KaritKarma platform today.

Which programming languages do you use?

Go for high-performance APIs, .NET 10 for enterprise systems, Rust for systems programming and carrier-grade voice, Python for AI/ML, and TypeScript with Next.js for frontends. Every language listed on this page is in active production use across KaritKarma's 22 products.

Can you build carrier-grade telecom systems?

Yes. BitsPath Voice is a Rust PBX of roughly 517,000 lines of code running SIP, RTP, SRTP, WebRTC, and a SIGTRAN SMS gateway in production. RADIUS AAA and ISP billing ship inside ISPChamp.

What AI and ML work have you shipped?

Sotto runs sub-500ms voice AI for UK restaurants on .NET 10 with Groq Llama 4 Scout. NewsForge runs an 11-stage autonomous pipeline. Aegis delivers real-time fraud scoring for banks and mobile financial services. Boooks, Kuhok, and Professional Vault all ship semantic search, CLIP, and facial recognition.

Do you run your own data center?

Yes. KaritKarma is an APNIC member with ASN 64005, owns IP blocks, and runs a Tier-3 data center in Dhaka with a Sirajganj DR site. We do not depend on a single hyperscaler for client workloads.

Is everything you list backed by shipping software?

Yes. Every language, protocol, infrastructure capability, and AI workload on this page is backed by a KaritKarma product that is in production today. We do not list capabilities we have not shipped.
