Applied AI Development

We build production-grade artificial intelligence systems designed to solve operational problems. Our architectures prioritize data safety, deterministic workflows, and cost management.

AI That Solves Operational Problems

Most enterprise AI initiatives fail because they start with models rather than problems. Chatbot demos are simple to build, but production-grade AI systems require strict execution bounds. We build applied AI architectures to optimize core business operations: improving workflows, reducing repetitive administrative decisions, and providing operational visibility. We avoid unnecessary complexity, selecting model sizes and embedding pipelines only when your data structures and performance budgets require them.

What We Build

We design and integrate system-level AI components designed for business automation and data retrieval:

  • 01 / Retrieval-Augmented Generation (RAG) Pipelines
  • 02 / Semantic Search & Knowledge Retrieval Engines
  • 03 / Internal Business Copilots & Assistants
  • 04 / Automated Document & Invoice Processing Pipelines
  • 05 / Custom AI APIs & Model Orchestration Layers
  • 06 / Business Intelligence & Analytics Assistants

AI Before Models

An AI model is only as effective as the system architecture surrounding it. We begin by defining the operational boundaries, identifying data assets, and setting success metrics before selecting technologies:

Understand Business Constraints

We identify repetitive decisions, document latency budgets, and map user access privileges first.

Prepare Clean Data

We extract, deduplicate, and partition your proprietary data sources, ensuring the AI model receives accurate context.

Model Selection

We select model sizes and embedding pipelines only after the system architecture, costs, and privacy boundaries are fully specified.

AI System Architecture

Production-ready AI requires a multi-layered system design. We construct resilient pipelines that handle latency, cost, and safety boundaries:

Retrieval & Embedding Layer

Converts raw text into semantic vectors using chunking algorithms and indexes them in low-latency search databases.

Prompt & Context Pipeline

Assembles dynamically retrieved database context, system rules, and user inputs into structured templates, applying semantic caching to save API costs.

Execution & Guardrail Layer

Executes LLM queries, validates schema formats, blocks prompt injections, and applies fallback rules (like routing to local models if API limits are hit).

Observability & Evaluation

Logs request latency, token costs, embedding drift, and accuracy rates, ensuring the system improves continuously over time.

Technology Decisions & Trade-offs

Building production systems requires objective evaluation. We present technology selections as choices with distinct characteristics, matching them to your operational requirements:

Hosted Models vs Local Models

**Hosted APIs (OpenAI/Gemini):** Offer high reasoning capabilities, zero server maintenance, and simple setups. The trade-offs are variable API latencies (often over 2 seconds), recurring usage costs, and data privacy concerns if processing sensitive client information.
**Local Models (Llama/Mistral on Private VPS):** Guarantee absolute data privacy, zero usage-based fees, and predictable execution latency. The limitations are server hardware costs (requires GPUs) and complex deployment maintenance.

RAG vs Fine-Tuning

**Retrieval-Augmented Generation (RAG):** Dynamically injects context into the prompt, making it ideal for platforms where data changes rapidly. It is cost-effective, easy to debug, and virtually eliminates hallucinations.
**Fine-Tuning:** Permanently updates model weights. It teaches the model specific tones, custom formatting rules, or domain terminologies. Fine-tuning does not teach new facts reliably and requires significant dataset preparation.

Open Source Models vs Proprietary Models

**Open-Source (Llama/Mixtral):** Provides total model ownership and allows self-hosting on private servers, eliminating vendor lock-in.
**Proprietary (OpenAI GPT-4o):** Provides superior general reasoning and zero setup effort, but leaves your system dependent on third-party pricing changes and deprecation schedules.

Vector Database vs SQL Search

**Dedicated Vector Databases (Pinecone/Qdrant):** Optimized for high-frequency semantic searches on millions of complex text dimensions.
**SQL Semantic Extensions (pgvector in PostgreSQL):** Keeps your data stored in a single, relational database, simplifying transaction logic and backups. pgvector is our default choice for systems with moderate data volume because it eliminates infrastructure sprawl.

Agentic Workflows vs Deterministic Automation

**Agentic Workflows:** Allow models to dynamically select and execute tools. It is flexible, but has variable execution loops and unpredictable failure states.
**Deterministic Automation (Code-Driven):** Enforces strict state machines. The AI model only runs specific classification or extraction steps, ensuring outputs remain predictable and secure.

Bhejna

An event-driven WhatsApp messaging engine proxy. We engineered a low-latency proxy in Go, using event loops and semantic KV caching to log message delivery states with sub-10ms latency.

Internal Product

Engineering Principles

Our AI architectures are governed by strict engineering safety guidelines:

1. Simple Systems: We do not add complex model configurations or orchestration frameworks until database context retrieval requires it.

2. Reliable Outputs: We enforce type-safe JSON schemas, preventing model outputs from breaking API integrations.

3. Human Oversight: We design human-in-the-loop validation screens for high-risk decisions (such as document publishing or pricing changes).

Lessons We've Learned

We are honest about design tradeoffs and failures in production AI:

Prompt Engineering is Not Enough

Relying solely on complex prompts causes output drift. We combine structural code validations, schema enforcement, and parameter constraints to ensure consistent outputs.

Data Quality Over Model Size

Fine-tuning a massive model with noisy, unstructured data underperforms. We focus on clean data extraction, deduplication, and database partitioning to feed smaller models accurate context.

Automation Without Review Fails

Allowing AI models to update production databases directly causes data corruption. We design staging areas and user validation dashboards to review model outputs before committing changes.

Smaller Focused Systems Outperform

Building massive, multi-step agent networks introduces high API latencies and run errors. We deploy small, dedicated pipelines that handle single classification or extraction tasks, keeping systems fast.

Frequently Asked Questions

When does a business actually need AI?

AI is appropriate when you process unstructured text data (such as emails, PDF documents, or customer support transcripts) that standard SQL query logic cannot classify or route. If your workflows can be resolved with deterministic, code-driven logic, traditional software is faster and more cost-effective.

Should we use ChatGPT or a local model?

If your data contains sensitive client credentials, or you require sub-100ms execution times with zero API fees, a local model (e.g., self-hosted Llama 3) is preferred. If you need general reasoning on unstructured documents and can tolerate variable latency, hosted APIs (like OpenAI) are easier to deploy initially.

Do we need fine-tuning?

Usually no. Fine-tuning does not teach new facts or dynamic database data to a model; it is used to teach a specific writing tone or output formatting. For factual retrieval, implementing a Retrieval-Augmented Generation (RAG) pipeline is more reliable, secure, and cost-effective.

What is Retrieval-Augmented Generation?

Retrieval-Augmented Generation (RAG) is a system architecture that queries a database for relevant context matching the user's request, and then passes those matching facts directly into the prompt template. This ensures the AI model base query relies on verifiable company data, minimizing hallucinations.

Can AI integrate with our existing software?

Yes. We build custom API proxies, background webhook receivers (in Go/SvelteKit), and semantic caching layers that integrate into your existing database and infrastructure.

How do you protect sensitive data?

We implement strict data scrubbers, anonymize personal identification data before passing context to public APIs, and set up self-hosted, local models inside your private Cloudflare or VPC network to keep data isolated.

How do you evaluate AI quality?

We set up validation datasets, trace semantic similarity scores between model outputs and golden references, and log token expenditures, error states, and latency in dashboards.
