About
Dayel Ostraco
CTO · Accelera Solutions
Currently CTO at Accelera Solutions, an AI-first company delivering ATO-ready AI agents for federal missions. Seventeen years engineering secure, full-stack platforms for federal, defense, and public-sector clients — integrating generative AI, LLMs, and real-time data pipelines into systems that hold under Zero Trust, RMF, and FedRAMP / HIPAA.
I lead Agile teams, ship code daily, and prefer playbooks over PowerPoints. Trusted by the DoD, DHA, SSA, CMS, and global financial institutions to architect platforms that move billions in transactions, scale to millions of daily users, and survive the audit afterward.
What I do
Three disciplines, one delivery model.
Tier 01
AI Integration
- ▸Multi-provider LLM orchestration — OpenAI, Claude, Gemini, LLaMA, Mistral, Bedrock
- ▸Deterministic agent pipelines with byte-identical artifacts
- ▸Grounded retrieval, prompt engineering, model lifecycle management
- ▸CUI-aware logging and audit trails
Tier 02
Secure Architecture
- ▸Cloud-native systems on AWS GovCloud, Azure, GCP
- ▸Microservices behind Zero Trust gateways and federated identity (iAS, DS Logon, OAuth)
- ▸Container hardening — FIPS 140-3 distroless, Iron Bank, Chainguard
- ▸Hybrid and multi-region cross-cloud designs
Tier 03
Federal Delivery
- ▸Authority to Operate (ATO), RMF, FedRAMP High, HIPAA, MEDCOI
- ▸STIG-compliant deployments and eMASS submissions
- ▸End-to-end DevSecOps from GitLab pipelines to production cutover
- ▸Agile leadership across cross-functional teams
The lab
A self-contained AI lab. IL4-equivalent control set. Architected for IL5 and IL6.
I built and operate a self-contained lab where authorized AI agents — Glyphon playbooks, Colophon engineering teams, custom workloads — run against an IL4-equivalent control set: closed-network boundary, federated identity, no external telemetry, per-action audit. The same architecture extends to IL5 and IL6 for classified mission deployments.
IL4
Equivalent today
Closed-network boundary, federated identity, multi-provider orchestration, hash-chained audit, no external telemetry.
IL5
Architected
Architecture extends to IL5 controls. Boundary, identity, and audit primitives already in place.
IL6
Designed
Patterns and segmentation designed for classified workloads. Ready for sponsorship and accreditation.
Flagship product
Multi-provider AI agent orchestration with deterministic compliance output.
Multi-agent compliance pipelines producing byte-identical artifacts across OpenAI, Claude, Gemini, and AWS Bedrock. Seven production playbooks covering CVE resolution, AMI and container hardening, eMASS POAM submission, and FedRAMP SSP generation. Validated at IL5 on AWS GovCloud with LLaMA 4 Maverick — April 2026, 9/9 green AMI hardening end-to-end.

Catapult Blockchain
Founder · Sold to Linxens
Founded a secure identity engineering firm delivering cloud-native, API-driven solutions for high-security banking and federal mission environments. Led design and implementation of mSTAX — a modular full-stack platform for the Department of the Navy and DHA evaluating AI/ML and LLM inference workloads in mission-critical environments. Built Linxens dLoc, combining blockchain and NFC-linked physical documents to create tamper-resistant digital twins.
- ▸ mSTAX showcased at 2018 DHA Open House
- ▸ ATO under HIPAA + MEDCOI
- ▸ Multi-region AWS + Azure cross-cloud
- ▸ Acquired by Linxens, June 2019
