What I Do

Where Strategy Meets Execution

I operate at the intersection of business outcomes and technical precision — turning complex requirements into deployable solutions.

PreSales & Client Discovery

Lead discovery sessions to uncover security gaps, translate business requirements into technical solutions, and support full deal cycles from RFP to close.

AI & Secure Architecture Design

Design end-to-end AI and cybersecurity solutions — architecture diagrams, technical proposals, and scalable system blueprints aligned to client risk posture.

Demos, PoCs & Technical Presentations

Build and deliver compelling proof-of-concept environments and executive presentations that convert technical complexity into clear business ROI.

SIEM & Threat Detection

Implement SIEM platforms (Splunk, Microsoft Sentinel, Wazuh), build detection rules and correlation logic, and establish structured SOC operations.

Compliance & Governance

Advise on ISO 27001, NIST, CIS Benchmarks, and OWASP frameworks — mapping controls to real infrastructure and producing executive-ready compliance documentation.

Cloud Security & Integration

Secure Azure and AWS environments with cloud-native logging, API security hardening, and cloud migration strategies that don't compromise on risk management.

Solutions

What I Deliver

Four core practice areas. One integrated approach to technical excellence.

Discover. Demo. Win.

PreSales Engineering

Technical presales that closes deals. I run discovery sessions, build custom demo environments, and craft RFP/RFI responses that turn technical complexity into clear business ROI.

  • Client discovery & requirements analysis
  • Custom demo & PoC environments
  • RFP / RFI technical responses
  • Solution scoping & stakeholder alignment
  • Sales-to-engineering handoff

Protect. Detect. Respond.

Cybersecurity Consulting

End-to-end security advisory from threat modelling to SIEM implementation. I design architectures aligned to NIST, ISO 27001, and CIS Benchmarks that don't slow your business down.

  • Threat modelling & vulnerability assessments
  • SIEM deployment (Splunk, Sentinel, Wazuh)
  • Incident response planning
  • Zero-trust architecture design
  • Compliance readiness (ISO 27001, NIST)

Build. Train. Deploy.

AI Solutions

From ML pipelines to NLP-based emotion detection — I design and deliver AI solutions that are practical, explainable, and production-ready.

  • ML model design & prototyping
  • NLP & sentiment analysis pipelines
  • AI integration with existing systems
  • Streamlit & Python-based AI apps
  • Responsible AI & explainability

Design. Scale. Secure.

Cloud & Architecture

Cloud-native infrastructure design with a security-first mindset. I architect Azure and AWS environments that scale gracefully while managing cost and risk.

  • Azure & AWS solution design
  • Cloud-native logging & monitoring
  • API security hardening
  • Cloud migration strategy
  • Infrastructure as Code

Case Studies

Problems Solved, Impact Delivered

Real engagements. Measurable outcomes. No filler.

Cybersecurity

SIEM & Vulnerability Assessment

Problem

The organization had limited visibility across 50+ endpoints and web-facing systems, with no structured process for tracking vulnerability remediation or detecting threats in real time.

Solution

Performed comprehensive vulnerability assessments, triage of security incidents by analyzing system logs and access anomalies, and monitored endpoint telemetry aligned to known threat actor techniques.

Impact

Coordinated remediation with engineering teams, reducing Mean Time to Remediate (MTTR) by 30% and establishing structured incident response processes to prevent recurrence.

Seed Health Prediction App

Problem

Cold storage facilities had no automated way to monitor potato seed health — staff relied on manual checks, leading to delayed detection of deteriorating conditions.

Solution

Built a Streamlit ML app using a RandomForestClassifier trained on environmental sensor data (Temperature, Humidity, CO₂) to predict seed health as Good, Fair, or Poor in real time.

Impact

Delivered a fully deployed Streamlit app giving facility operators instant health status visibility from sensor inputs, with visual health status feedback.

Enterprise AI PreSales Demo — Simtech

Problem

Sales cycles stalled because prospects couldn't visualize how AI and cybersecurity solutions mapped to their specific operational workflows and risk environments.

Solution

Built modular, configurable demo environments tailored per vertical — enabling live customisation during prospect calls with real SIEM dashboards, AI output visualisations, and architecture walkthroughs.

Impact

Shortened average sales cycles and increased demo-to-pilot conversion rates, directly contributing to pipeline acceleration and deal closures.

Security Research

Active Directory Home Lab — MITRE ATT&CK

Problem

Needed a real-world simulation environment to validate detection coverage across enterprise attack scenarios, particularly for authentication anomalies and lateral movement.

Solution

Designed a simulated enterprise environment using Windows Server, Splunk, and Kali Linux — built logging pipelines, correlation rules, and dashboards modelled on professional SOC workflows.

Impact

Validated detection coverage across 15+ MITRE ATT&CK techniques, with findings documented in structured reports mirroring technical advisory deliverables.

Why Security is a Sales Problem

Most security failures aren't technical — they're communication failures. The gap between what engineers know and what executives fund is where breaches happen.
