Top rated, very hands on, IT Systems Architect and Lead Developer with a proven track record that spans more than two decades in both the Private and Public sector. Legit out-of-the-box thinker with problem solving abilities that have consistently provided original innovating solutions or saved heavily invested ones from sinking. ** My 4.2 stars rating is only due to a 9-years old 100K project that was successful but the client only rated it 4.0, due to his particular style of being strict with ratings. This rating only took effect recently due to Upwork making the choice to include LIFETIME ratings. Without it, my overall stars rating would be 4.9** My hard earned skills & experience are backed by a solid formal education in computer science at top-tier US and UK Technical Universities; I hold an MSc in Computer Science from Heriot-Watt University and, during my 6 years with European Commission's Cybersecurity department, I led the development & successful delivery of projects as important as the European Root Certification Authority for EU's Digital Tachograph: dtc.jrc.ec.europa.eu After years of tackling the hardest of IT projects, I am now a true all-rounder that, for the past couple of years have been involved in complex, real world projects built around fine tuned multi-LLM pipelines for reasoning, vision and multi-modal tasks. - AI-integrating endpoint protection using WFP kernel drivers, ETW/Sysmon telemetry, machine learning and on-device LLM reasoning (dual local LLaMA tiers, ONNX/NPU acceleration, behavioral-rule detection), autonomous response logic (graduated SOAR, cryptographic update channels) and WinUI 3 GUIs.

I help organizations identify, emulate, and defend against real-world adversaries before attackers can exploit them. My expertise spans offensive security, adversary emulation, exploit development, malware engineering, AI security, Active Directory, Network and Web penetration testing. Rather than relying solely on publicly available tooling, I focus on understanding how attacks work at a low level, enabling me to develop custom tradecraft, validate attack paths, and deliver practical security improvements that go beyond automated scanning. Areas of Expertise: Adversary Emulation & Red Team Operations Web, API & Network Penetration Testing Active Directory Security Assessments Exploit Development Malware Development & Analysis Custom Shellcode Development C2 Infrastructure (Sliver, Metasploit & Custom C2 Tradecraft) Detection Evasion Research (Microsoft Defender, CrowdStrike & EDRs) AI & LLM Security (Prompt Injection, Jailbreaks, AI Red Teaming) OSINT & Attack Surface Discovery Vulnerability Research & Responsible Disclosure My offensive security philosophy is simple: understand the attacker first. I have developed custom shellcode from scratch as part of advanced malware development training, built custom proof-of-concepts, modified payloads, researched exploit chains, and implemented techniques to better understand how modern endpoint detection and response solutions identify malicious activity. This low-level understanding allows me to tailor offensive tooling instead of simply deploying publicly available payloads. My experience includes working extensively with frameworks such as Sliver, Metasploit, and custom tooling while researching process injection, shellcode execution, payload staging, AV/EDR evasion techniques, and command-and-control tradecraft in authorized environments. I have also extensively studied and applied the training material from CRTP and OSEP, and I am comfortable applying the techniques covered in those courses including advanced Active Directory attacks, pivoting, lateral movement, C2 operations, and post-exploitation workflows. My engagements span across: OSINT & attack surface discovery External and internal reconnaissance Web & API security assessments Active Directory enumeration and attack-path analysis Initial access validation Privilege escalation & lateral movement Adversary emulation Custom exploit & proof-of-concept development Malware and payload research Executive & technical reporting with actionable remediation Beyond traditional penetration testing, I conduct AI security assessments focusing on prompt injection, indirect prompt injection, agent security, insecure tool use, model abuse, and data leakage to help organizations deploy AI systems securely. I hold certifications including CPTS (Hack The Box), CEH, CRTA, and ISC2 Certified in Cybersecurity, while continuously advancing my skills through research into exploit development, malware engineering, Windows internals, offensive tooling, and enterprise red team methodologies. I've worked with organizations ranging from startups preparing for launch to global technology companies, including Microsoft. Whether you need a penetration test, adversary emulation, exploit development, AI security assessment, malware analysis, or offensive security consulting, my objective is to emulate realistic threats, demonstrate measurable impact, and provide remediation that meaningfully improves your security posture. The best security assessments don't just find vulnerabilities, they demonstrate how an attacker would chain them together to achieve real business impact.

Your data is a mess and you're still guessing why users don't pay or churn. I fix both. I build the analytics infrastructure, warehouse to dashboard, that you can actually trust, so you see exactly where users drop and what to fix. Mixpanel Certified Partner & PostHog expert, 100+ companies, Top Rated Plus. As a founder or product & growth person, one of the major pain points is to completely understand how your users are using your product & use the insights to drive the business forward. But insights are only as good as the data infrastructure underneath them. That's exactly what I help you build - from the warehouse up to the dashboard. I'm Ansh, a Product Analytics expert (Mixpanel Certified Partner) and data engineering practitioner, who has worked with 100+ companies to set up their analytics and data infrastructure to accelerate insights that drive product growth & revenue. Tech Stack: DBT, Fivetran, Bigquery, Mixpanel, Amplitude, Posthog, Google Tag Manager, Google Analytics, Hotjar, Looker Studio, Databricks, Metabase, Tableau, Power BI, etc. What exactly can I help you with? โœ… CRO: I identify friction in your funnels and optimize flows to improve conversions across signup, activation, and revenue. โœ… Data modeling & warehouse design: I build clean, well-documented data models using dbt so your warehouse is analysis-ready - not a mess of raw tables nobody trusts. โœ… Data pipeline setup: I configure and maintain ingestion pipelines using Fivetran, Airbyte, or custom connectors so your product, marketing, and revenue data lands reliably in BigQuery, Snowflake, or Redshift. โœ… AI-ready data infrastructure: I structure and document your data so it's ready for AI agents, LLM-powered analytics, and automated reporting - not just human dashboards. โœ… Consulting: I guide teams on what to measure, how to analyze it, and how to make data-driven decisions that drive growth. โœ… A/B testing: I design and analyze A/B tests so you can ship changes backed by statistically sound results. โœ… Ad-to-product attribution: I set up pipelines to send Google/Facebook/LinkedIn Ads data into Mixpanel, Amplitude, or Posthog for full-funnel attribution. โœ… Event tracking, schema design & data modeling: I create clean tracking plans, warehouse schemas, and dbt models so you always collect the right data in the right structure โœ… Analytics strategy: I build an AAARRR-based analytics strategy so you know exactly how customers move through your product. โœ… Tool integrations & automation: I connect your tools and automate your data workflows across Mixpanel, Amplitude, Posthog, Segment, and more. โœ… Marketing โ†’ Product stitching: I connect your acquisition data with product usage to show which channels bring high-value users. What do people say about me? - Ansh was extremely helpful in developing our V2 analytics strategy and in setting up our Mixpanel dashboards accordingly. He was not only proactive in bringing his expertise but also highly adaptable to our specific needs. Ansh played a key role in identifying effective solutions where standard approaches were insufficient, delivering all his tasks with great professionalism and impressive speed. Looking forward to future projects with you, Ansh! - Ansh had skillfully set up our PostHog dashboard analytics, delivering a precise and effective solution. Highly recommend his expertise and commitment to quality. - Ansh has been excellent with setting up our mixpanel pipeline and providing insightful analytics. He's always available, humble, and always ready to learn more aboutย theย product! - Ansh was incredibly helpful in three main ways: first his detailed technical knowledge of MixPanel helped me solve specific implementation problems and needs quickly, usually within a few minutes. Second, he pushed me to frame my thinking about why I wanted a certain piece of analysis. This helped me get far clearer on my goals - sometimes leading to me running different analysis, dropping a piece altogether and always helping me think more strategically. Finally, Ansh has a lot more to offer thanย justย MixPanel advice - he's able to think strategically about North Star and second-level metrics, helping me figure out the why behind the work I was doing. If I seem fit for what youโ€™re looking for, feel free to DM!
