"I cannot say enough good things about Abubakar! I've yet to meet someone as meticulous and dedicated to delivering high-quality results." "Absolutely amazing. Amazing communication and cooperation, 11/10." These are a few of the several reviews I've received from my past clients. I've worked and freelanced for over 5 years and one thing remained constant: over 99% of the time, clients closed contracts with their expectations exceeded. I specialize in building good quality software. In our current AI powered digital world, developers like myself have found ourselves being able to write code 2-5x faster, but now, the most important aspect in software development has shifted from being able to write code, to who can keep up with the pace of code gen and keep your applications running 24/7. This is precisely where I come in, with my background as a software developer and recently a DevOps engineer. I make sure to keep code quality as the heavy priority throughout the development process. While I build software across a wide array of fields, here are the most common types of work I do: - Fullstack development (SaaS applications, dashboards, web apps) - Backend development (REST APIs with FastAPI, database design with MongoDB and Postgres, authentication, webhooks, background jobs) - Bot Development (Discord & Telegram bots, scrapers and crawlers) - AI Integrated applications (LLM integrations) Got a project idea, or not sure where to start? Message me and I can walk you through the steps I'd take to bring your idea to completion.

Most "AI agents" are demos that fall apart outside a sandbox. I build the ones that run in 𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧, 𝐰𝐫𝐢𝐭𝐞 𝐚𝐧𝐝 𝐞𝐱𝐞𝐜𝐮𝐭𝐞 𝐭𝐡𝐞𝐢𝐫 𝐨𝐰𝐧 𝐜𝐨𝐝𝐞 𝐬𝐚𝐟𝐞𝐥𝐲, and 𝐡𝐨𝐥𝐝 𝐮𝐩 𝐭𝐨 𝐚𝐧 𝐚𝐮𝐝𝐢𝐭.

Because self-written code is the obvious risk, safety came first: a dangerous-code linter built on Go AST parsing screens everything before execution, and a fully versioned Postgres schema (base_id + version + operation) gives a zero-data-loss audit trail of every agent action. Multi-LLM orchestration across OpenAI, Claude, Vertex AI, and Groq. Turned recurring back-office work — invoice OCR, email, document workflows — from hours of manual effort into minutes of supervised automation. 🕸 𝐏𝐨𝐥𝐲𝐦𝐞𝐫: 𝐄𝐧𝐭𝐢𝐭𝐲 𝐫𝐞𝐬𝐨𝐥𝐮𝐭𝐢𝐨𝐧 𝐚𝐧𝐝 𝐤𝐧𝐨𝐰𝐥𝐞𝐝𝐠𝐞 𝐠𝐫𝐚𝐩𝐡𝐬 𝐚𝐭 𝐝𝐨𝐜𝐮𝐦𝐞𝐧𝐭 𝐬𝐜𝐚𝐥𝐞 Architected a document intelligence platform for Predict Data Inc. that runs NER extraction over very large document sets and maps entity co-occurrence into a knowledge graph, surfacing relationships keyword search never returns. Distributed parallel ingestion, an NLP + vector search pipeline (Python, LangChain, OpenAI, PostgreSQL, S3), a custom extensible entity-type framework, and a graph query API shaped for network visualization. Cuts research that took analysts days down to a graph query, at a fraction of the per-document cost of manual review. 🛡 𝐓𝐫𝐮𝐞𝐀𝐮𝐝𝐢𝐞𝐧𝐜𝐞: 𝐑𝐞𝐚𝐥-𝐭𝐢𝐦𝐞 𝐚𝐝 𝐟𝐫𝐚𝐮𝐝 𝐝𝐞𝐭𝐞𝐜𝐭𝐢𝐨𝐧 High-concurrency Go backend that fuses device fingerprinting (canvas, fonts, timezone), IP intelligence, MaxMind GeoIP2, and external fraud databases into behavioral profiles that score ad traffic in real time. Low-latency scoring API for live blocking decisions, file-based buffering for very high request volumes, and batch analytics on top — protecting advertisers' spend from bot traffic. 🏦 𝐙𝐨𝐥𝐯𝐚𝐭: 𝐀𝐈-𝐏𝐨𝐰𝐞𝐫𝐞𝐝 𝐊𝐘𝐂 & 𝐏𝐚𝐲𝐦𝐞𝐧𝐭𝐬 𝐈𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 𝐟𝐨𝐫 𝐚𝐧 𝐄𝐌𝐈 𝐏𝐥𝐚𝐭𝐟𝐨𝐫𝐦 Ledger logic, SEPA payment flows, and service orchestration for an installment payments platform.

Automatic composition cut post-exam video processing from hours to minutes, with bandwidth optimization for students on weak connections and full audit trails for post-exam review. 📅 𝐏𝐒𝐈 𝐒𝐞𝐫𝐯𝐢𝐜𝐞𝐬 (𝐧𝐨𝐰 𝐩𝐚𝐫𝐭 𝐨𝐟 𝐄𝐓𝐒): 𝐒𝐜𝐡𝐞𝐝𝐮𝐥𝐢𝐧𝐠 𝐢𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 𝐟𝐨𝐫 𝐩𝐫𝐨𝐟𝐞𝐬𝐬𝐢𝐨𝐧𝐚𝐥 𝐜𝐞𝐫𝐭𝐢𝐟𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐭𝐞𝐬𝐭𝐢𝐧𝐠 Serverless middleware layer connecting exam providers to PSI's core booking system: multi-portion exams, accommodations, and sub-second real-time test-center availability via a Redis caching layer that sharply cuts upstream API load, across national client integrations.

Production-ready means sandboxed, audited, monitored, and handed over properly, not a proof of concept that breaks under real load. And every claim on this profile is one I can walk you through in the code. Good fit if you're deploying AI agents or LLM systems into a real workflow, not just prototyping, you have budget for production-grade work ($5K+), and you want me hands-on in the code, with a team behind me when the work needs to scale. Not a fit if you're shopping purely on rate, or you want a demo with no plan to ship it. If your AI system needs to survive contact with production, send me a message.
