I help startups and businesses build AI applications, from SaaS products and internal tools to AI assistants and Voice AI platforms. My goal is simple: build software that solves real problems and fits naturally into the way people work.
I have over 7 years of experience building web and mobile applications, and in recent years my focus has been on AI-powered products. I've worked with startups across healthcare, education, SaaS, real estate, and enterprise software.
One of my recent projects was helping build the AI infrastructure for a Voice AI platform that handles inbound and outbound phone calls. The challenge wasn't integrating an LLM, it was making conversations feel natural while keeping response times low and giving the AI the right information at the right moment.
Many AI projects stop after connecting a model. That's only the beginning. The real work is deciding what the AI should know, how it retrieves information, when it should take action, and how the application behaves when things don't go as expected. That's the kind of work I enjoy.
I use AI tools where they genuinely save time, but they're just one part of my workflow. The architecture, technical decisions, and implementation still come from experience.

I provide the strategic oversight of a Fractional CTO/Principal Architect combined with the execution power of a 40-person engineering team. We deliver complete, production-grade AI systems—from Multi-Agent workflows to Computer Vision—at scale.
I serve as a Strategic Technical Partner for businesses that need to deploy cutting-edge AI but lack the internal infrastructure to build it. While most freelancers focus solely on a specific task, I provide the architectural vision, while my dedicated team handles the end-to-end execution.
Backed by my Ph.D. and a powerhouse team of 40+ engineers, I bridge the gap between complex algorithmic foundations (ML/CV/Multi-agentic Orchestration) and consumer-ready applications (Web/Mobile).
🔹 The Engagement Model: Strategy + Scale
I am not a developer who you manage; I am the Architect who ensures you succeed.
- My Role (Strategic Oversight): I act as your high-level technical advisor. I design the system architecture and select the right tech stack to ensure ROI.
- The Team (Execution): Once the strategy is set, I deploy a specialized pod of engineers (led by a Senior Lead) to build your solution.
🔹 The "Feasibility First" Guarantee (Avoiding the Hype Trap)
Many clients come to us after failed experiences with developers who overpromised. We operate differently:
- Reality Checks: We assess your requirements against current AI capabilities. If an idea is technically impossible or commercially unviable, I will tell you upfront. I protect your budget by filtering out "magic," focusing only on what is buildable.
- Paid Experiments (PoC): For high-risk or novel ideas, we do not guess. We run a structured, paid Proof of Concept phase to validate the tech before you commit to a full-scale build.
- Technical Candor: If a simpler non-AI solution works better, we will recommend it.
🔹 Core Technical Pillars
We don't just wrap APIs; we build custom, high-performance solutions when needed.
1. Multi-Agent Systems & Hyper-automation
• Orchestration: Building "Teams of Agents" (using LangGraph/CrewAI) that collaborate to handle complex workflows (e.g., Sales Outreach → CRM Update → Email Drafting).
• Reasoning Models: Implementing advanced reasoning (o1/DeepSeek) for tasks requiring logic, planning, and multi-step execution.
• Voice Agents: Real-time, human-parity voice AI for customer support and inbound sales (Retell AI/Vapi/ElevenLabs).
2. Machine Learning & Predictive Intelligence
• Custom Models: Regression, Classification, and Clustering for business insights.
• MLOps: Data pipelines for large-scale processing and predictive maintenance.
3. Multimodal Perception (Vision + Action)
• Computer Vision: Object detection, segmentation, and tracking (YOLO, OpenCV) integrated with decision-making agents.
• Visual Agents: AI that can "see" screens, documents, or physical feeds to automate quality control or data entry.
🔹 End-to-End Product Delivery
An AI model is useless if users can't access it. We build the full ecosystem:
• Mobile: Native iOS (Swift) and Android (Kotlin), or Cross-platform (React Native/Flutter).
• Web: Scalable React/Next.js frontends with robust Python backends.
• Enterprise RAG 2.0: Secure, hallucination-free knowledge retrieval with governance guardrails (PII masking/Compliance).
🔹 Why Partner With Me
- Co-located Studio Team: We are not a scattered network of remote freelancers. My team works together in a physical office, ensuring real-time collaboration, higher data security, and zero communication gaps.
- PhD-Backed Rigor: We ensure your solution is technically sound, avoiding the common pitfalls of "hallucinating" AI or over-fitted ML models.
- Proven Scale: 100+ solutions delivered globally with a 100% Job Success score.
Let’s discuss your vision.
I am available for an initial consultation to evaluate technical feasibility and determine if my team is the right fit for your project.

🔝 Let's jump into this ultimate success boat.
⏩ My Full-Stack development experience includes C#, ASP.NET MVC, .NET Core, Angular, React, Node, and Flutter for mobile applications, overall I am capable of creating end-to-end systems that are performant, secure, and capable of scaling.
Here is an overview of the languages, frameworks, libraries, and design patterns I have worked with for Back-end Development:
✔️ C# .NET CORE (.NET 3.1 & .NET 6, .NET 8)
✔️ ASP.NET MVC & ASP.NET Web API (Entity Framework, SignalR, CQRS Pattern, Clean/SOLID Architecture, Three-layer architecture, Asynchronous Programming, Dependency Injection with Autofac/Unity, AutoMappers, Generics, API development, Repository pattern, Razor Syntax, Web Pages, State Management through sessions & JWT-based authorisation, SeriLog, Log4net, Error Handling)
✔️ API Development (Using ASP.NET Web API, .NET Core APIs, Node, Nest.js Framework, authentication & authorisation using JWT Web tokens, Passport.js, Firebase)
✔️ Cloud Platforms (Microsoft Azure, App/Cloud services, Redis cache, Service bus, Queues, SignalR, Azure SQL, App Insights, Azure Functions, Storage accounts, vNet integration, Azure DevOps, Google Cloud Platform (GCP), Amazon Web Services (AWS), Lambda, S3 Storage)
✔️ DevOPS (CI/CD using Azure DevOps & Github Workflows)
✔️ API Integration (Google API's integration including Google Authentication using oAuth 2.0, Google Drive APIs, Google My Business APIs, Places, Google Ads, Google Analytics, Calendar, Youtube, Pub/Sub. Payment API Gateways for Stripe, QuickPay, Cardcom, and CreditGuard. Integrated ChatGPT and Claude Sonnet 3.5 models into SaaS Web applications and in AI-Chatbots. API Integrations for Salesforce, Powerlink, HubSpot, Teamwork, Twilio, ZOHO CRM API, WhatsApp Business API, Freedcamp, Facebook Graph API, Twitter/X API, Spotify, Soundcloud, Zoom, and MS Teams API integrations etc.
✔️ Databases (MSSQL, Postgres, MySQL, Mongo, Firebase (Firestore), Azure Cosmos)
✔️ Extensive ErpNext Development (Python/JavaScript) in Frappe framework with integration of eBay APIs, Stripe and managing Shopify inventory inside ErpNext.
✔️ WPF (Windows Presentation Framework) for building desktop-based applications along with .NET MAUI app development.
For Front-end development, my strengths include:
✔️ Angular (Angular Universal or Server-side rendering, Typescript, analysing builds with bundlers for optimisation, crafting modules, working with routing, lazyloaded modules, authentication guards, HTTP services, standalone components, Angular Signals, shared services using RxJS, NgRX, localStorage, SignalR integration, PrimeNG, Angular Material UI and SyncFusion).
✔️ Reactjs (ReactDOM, Redux, React Router)/Next.js
✔️ Javascript (In a world full of front-end frameworks, we often forget the importance of underlying Javascript. I worked my way up from Javascript and jQuery to Angular back in 2016)
✔️ Web Design (CSS 3, Bootstrap, Tailwind, PrimeFlex, and Figma to Web Design)
For Mobile Applications, I primarily use Flutter with either Firebase/Supabase or custom API integration if not for SqlLite. Here's the summary of my experience with Flutter:
✔️ Flutter (Stateful/Stateless widgets, Providers especially Consumer/Select, ListViewBuilder, Push notifications based on the reminders, StreamBuilders, FutureBuilders, Flutter widget life-cycle, working with the data, Firebase & SqlLite, Shared-Preferences).
✔️ AI-Powered Chatbot Development using ChatGPT/OpenAI or Claude APIs.
✔️ MCP Server Integrations and Development
✔️ Agentive AI Applications - using a function or tool calling
✔️App deployments on both Google Play Store and Apple App Store
For Automations, I have used n8n (cloud-based and locally) extensively to create workflows, Zaiper (multi-step zaps, custom API integration, etc), Airtable, GHL Workflows, and make.com. To write automated scenarios, I have used Playwright and Selenium WebDriver.
I have written a lot of custom automations using AWS Lambda, GCP and Azure functions, which generally either use time triggers (called after a set interval) or HTTP-based triggers, used as Webhooks. Some of the automations that I have worked with
include Slack apps & integrations, Notion, Telegram, Pushbullet, performing sync on Shopify products and their variants in the background, sync to or from BigQuery offered by Google Cloud, updating CMS, writing auto posting on social media based on
a text-based prompt that generates an image using Gemini APIs and posts it on selected social media channels. Another example is automatically transferring Teams meeting recordings to a Google Drive folder using APIs or writing Google Sheets scripts to execute APIs and manipulate the returned response."

I design and build production-ready AI products : on 3, 6, 9, and 12-month contracts.
If you're a product developer who needs someone to own the engineering end-to-end, not just write code, but make the right calls; that's what I do.
With 10+ years of experience, I've moved fast on hard problems: custom LLM applications, intelligent automation, fullstack AI products across web and mobile, and the infrastructure to run them reliably in production.
What I build:
Fullstack AI web & mobile apps • Custom LLM integrations • Intelligent automation systems • Data pipelines & model deployment infrastructure
AI & ML:
LangChain / LangGraph / LangSmith • OpenAI, Claude, Gemini • Hugging Face (fine-tuning, deployment) • TensorFlow, PyTorch • Stable Diffusion, LoRA/QLoRA • Recommendation & generative AI systems
Stack:
Python, TypeScript, SQL • Google Vertex AI, AWS SageMaker • Nvidia NIMs, Groq • Advanced data processing & feature engineering
I don't hand off prototypes. I build things that hold up architected to scale, easy to maintain, and optimized for real-world performance, not just benchmarks.
I've also mentored 1,000+ students in engineering, which means I communicate clearly, flag issues early, and never leave you guessing on where things stand.
If you're building something serious and need a contractor who moves with urgency, let's talk.
