Services

Everything you need to design, build, and run a system.

Engagements are scoped to the problem, not squeezed into a fixed package. Below is the full range of what we do — pick one, or combine a few.

VOICE & NLP

Smart Call Center & Turn Management

A voice AI engine capable of real-time turn-taking perception, contextual data collection, and human-like conversational responsiveness — built to run a call center, not just answer a phone.

  • Real-time voice turn-taking perception
  • 24/7 automated call handling
  • Contextual data collection during calls
  • Human-like conversational responsiveness
MULTIMEDIA

Live & Synthetic Video Generation

Real-time conversational synthetic avatars using real or generated faces, with end-to-end video synthesis that synchronizes speech, facial animation, and audio into one coherent output.

  • Real-time conversational synthetic avatars
  • Real or fully generated faces
  • Speech-synced facial animation
  • End-to-end audio/video synthesis
EDTECH

AI Examination, Analytics & Academic Coaching

Visual question generation, automated assessment analytics, psychology-informed evaluation models, and personalized academic coaching mechanisms for schools and training platforms.

  • Automated visual question generation
  • Assessment analytics & scoring
  • Psychology-informed evaluation models
  • Personalized academic coaching
DATA & RAG

Advanced RAG & Domain Expert Agents

Autonomous domain-expert agents that use dynamic multi-source synchronization, document grounding, and real-time web search to answer questions with evidence, not guesses.

  • Autonomous domain-expert agents
  • Multi-source data synchronization
  • Document grounding for accuracy
  • Real-time web search integration
CONTENT

Video Intelligence, Podcasts & Presentations

Long-form video processing that extracts structured documentation, automated presentation slide generation from text, and end-to-end podcast creation from a single source.

  • Long-form video-to-document extraction
  • Automated presentation generation
  • Text-to-podcast production
  • Structured content from raw media
SOFTWARE ENG

Prompt-to-Production & Web Engineering

Infrastructure for rapidly transforming natural-language prompts into working software applications, alongside modern, scalable web architectures built to carry real traffic.

  • Natural language to working software
  • Rapid prototype-to-production pipelines
  • Modern, scalable web architectures
  • Full-stack engineering support
SECURITY

Autonomous Security & Vulnerability Remediation

An AI agent pipeline that audits source code and architectural security flaws, then automatically generates and applies code patches to remediate what it finds.

  • Automated source code security audits
  • Architectural flaw detection
  • AI-generated patch code
  • Continuous vulnerability remediation
LANGUAGE AI

Translation, Speech & Summarization

Multilingual neural translation pipelines, context-aware document summarization, high-quality text-to-speech audio synthesis, and promotional video clip creation.

  • Multilingual neural translation
  • Context-aware document summarization
  • High-quality TTS audio synthesis
  • Promotional clip generation
Ways to work together

Three engagement models.

However the work starts, the handoff is the same: documentation, monitoring, and a team that can run without us.

PROJECT

Project-based

A defined scope, timeline, and fixed set of deliverables — for a specific build, migration, or launch.

Best for: a new product, a rebuild, or a clear one-off system.

EMBEDDED

Embedded team

Our engineers work inside your team and tools as an extension of it, for as long as the roadmap needs.

Best for: scaling delivery without a slow internal hiring cycle.

ADVISORY

Fractional & retainer

Ongoing technical leadership — architecture reviews, hiring input, and hands-on help by the month.

Best for: teams that need senior judgment, not full-time headcount.
