Agentic AI Tech Lead & Fullstack Group Lead

Agentic AI Tech Lead, Fullstack and Mobile Architect, and Group Leader at Tikal with over 15 years of experience designing and building complex software systems across Fintech, HealthTech, and mission-critical defense. I lead the adoption of Agentic AI across the software development lifecycle, helping R&D organizations move beyond ad-hoc prompting toward structured, spec-driven Agentic SDLC practices. I design and implement AI-powered development workflows, agentic architectures, LLM-based systems, tool-enabled agents, and MCP integrations that accelerate engineering delivery while maintaining architectural quality, reliability, and maintainability. I combine hands-on engineering experience across mobile, fullstack, distributed, and real-time systems with practical AI engineering expertise, helping teams turn emerging AI capabilities into repeatable engineering practices and measurable productivity gains. As a Group Leader, I mentor engineers, lead hands-on Agentic SDLC workshops, and help organizations build the engineering practices needed for the AI-native era.

Portfolio

AppWork

Agentic SDLC Consultant & Technical Trainer

At Appwork, I delivered an Agentic SDLC Workshop and Enablement Program for software engineers and tech leads, helping the team move from ad-hoc AI prompting toward a structured, governed Twelve-Factor Agentic SDLC. I trained developers to initiate features through version-controlled specifications (spec.md → plan.md → tasks.md), providing AI coding agents with a clear foundation for implementation and alignment with product requirements. I guided the team in building repository rules, AI constitutions, custom agent skills, and MCP tool integrations to ground agents in Appwork’s architecture, coding conventions, and development context. The program included hands-on work with Cursor, Claude Code, and Spec Kit, covering context engineering, agent workflows, tool calling, and AI-assisted testing and verification. I also introduced LevelUp as a continuous learning mechanism for capturing development insights, code-review feedback, and architectural decisions and turning them into reusable directives that improve future agent interactions and team workflows.

Presise

Agentic SDLC Lead & Technical Trainer

At Precise, I designed and delivered an intensive Agentic SDLC Enablement Program for software engineers, architects, and engineering managers, focused on accelerating development velocity while maintaining strong architectural and quality governance. I trained teams to apply structured agentic workflows across the software development lifecycle, including spec-driven development, synchronous and asynchronous agent execution, and “The Great Filter” quality gates that keep engineers accountable for AI-generated code. I introduced Directives as Code, architectural decision records, MCP integrations, and safe tool-calling practices to provide AI agents with the context and guardrails needed to work effectively within complex engineering environments. The program also introduced LevelUp, a continuous knowledge-capture loop that turns lessons from development, code reviews, and architectural decisions into reusable, version-controlled directives, enabling teams to continuously improve their AI-assisted engineering workflows. Hands-on sessions covered Cursor, Spec Kit, Claude Agents, and multi-agent collaboration patterns.

Sentrycs

Agentic Full Stack Engineer

As Fullstack Architect & Agentic SDLC Lead at Sentrycs, a global leader in Counter-UAS technology, I drove the delivery of mission-critical real-time C2 systems for drone detection, tracking, and mitigation. I applied Tikal’s Twelve-Factor Agentic SDLC principles directly to my engineering workflow, evolving AI-assisted development from ad-hoc prompting into a structured, spec-driven process using Spec Kit, AI constitutions, custom agent skills, and MCP integrations with tools such as Jira, GitHub, Figma, and DevTools. I architected complex operator interfaces and distributed backend services using React, TypeScript, MobX, OpenLayers, Python, NestJS, MongoDB, RabbitMQ, and WebSockets, delivering real-time map telemetry and resilient microservices. I combined agentic development with BDD/TDD quality gates, automated traceability, and architectural governance to increase development velocity while maintaining the reliability and engineering rigor required for mission-critical systems.

Legit Security

Fullstack Engineer

As a Fullstack Engineer at Legit Security, I designed and developed scalable, enterprise-grade capabilities for the Application Security Posture Management (ASPM) and software supply chain security platform. I created high-performance, real-time dashboards and asset-graph visualizations using React and TypeScript, enabling security teams to effectively trace vulnerabilities and assess pipeline risks from code to cloud. Additionally, I built resilient, distributed backend services and data-ingestion pipelines with Node.js to efficiently process high-throughput telemetry across multiple repositories.

Verbit

Fullstack Architect

For Verbit.ai, I took on the role of a single Tech Lead Developer, responsible for building their mobile application from scratch. This comprehensive project involved defining a strong architecture using Flutter and implementing key functionalities like WebRTC for real-time communication, WebSockets for efficient data exchange, and robust background work capabilities. The result was a seamless application that efficiently sends voice recordings and displays them as transcripts.

AutoDesk

Mobile Architect

At Autodesk, I joined their dynamic mobile team as a Mobile Architect, where I played a key role in the development of their Android application. My contributions included leveraging modern Android development practices such as reactive programming with Flow and Coroutines, and working extensively with local databases to sync user data across all projects with a robust sync system, ensuring data consistency and a seamless user experience.
