Experience
RedAmon: AI-powered Agentic Red-team Platform
https://www.redamon.org/Security is built into the foundation, with strict isolation and hard limits that make it impossible to aim at protected targets such as government systems, and the whole platform installs with a single command. RedAmon has grown into a thriving open-source project with over 2,200 GitHub stars, more than 200 daily downloads, and an active community of contributors, and is used by enterprises and security professionals worldwide.
pMag: Multi-tenant Agentic AI Platform
https://devergolabs.com/en/portfolio/pmag?platform=freelanceSMA: Smart Multi-agent Enterprise RAG Platform
https://devergolabs.com/en/portfolio/sma?platform=freelanceThe system automatically keeps itself up to date, picking up new and edited documents as they are added, so answers never go stale. It was built for real corporate use: single sign-on, strict access controls so people see only what they are allowed to, and enough efficiency to serve hundreds of employees at once on modest infrastructure. The result replaces slow, frustrating internal searches with fast, reliable, source-backed answers.
Pathbreak: Agentic Cloud Attack-path Platform
https://pathbreak.io/Every step comes with clear evidence, so findings can be trusted instead of second-guessed. Once the real attack paths are known, Pathbreak ranks the fixes that shut down the most routes at once, and a built-in AI assistant explains each path and its remediation in plain language. New attack techniques can be added as a simple configuration rather than new code, keeping it current as threats evolve. The result turns cloud security from a noisy checklist into a focused, prioritized action plan.
Reranka: Multi-marketplace BI and ML Platform
https://devergolabs.com/en/portfolio/multimarketplace_hub?platform=freelanceEverything is presented through visual, easy-to-read reports with one-click export, so business teams, not just analysts, can act on it. The platform handles enormous volumes of data reliably and refreshes throughout the day, giving decision-makers an always-current picture of their market.
