About
Dayel Ostraco
CTO · Accelera Solutions
Trusted by the DoD, DHA, SSA, and CMS — and by global financial institutions — to architect platforms that move billions in transactions, scale to millions of daily users, and survive the audit afterward. Currently CTO at Accelera Solutions, delivering ATO-ready AI agents for federal missions.
17 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.
What I do
Three disciplines, one delivery model.
Tier 01
AI Integration
From prototype to production AI — inside classified enclaves.
- ▸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
Systems that hold under audit and scale past 10M daily transactions.
- ▸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
ATO-ready from day one — eMASS-fluent, STIG-clean at deploy.
- ▸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.
